)
A)
好的,我发现WinForm程序是这样的:
我在一个按钮下尝试了它,然后运行…处理异常的结果:
无法在同一AppDomain中创建多个System.Windows.Application实例。
好的
B)
然后,我搜索了一个解决方案,有人说你必须在一个新的[不同的]AppDomain中执行它
例如,这里有一个答案:
我在LUNCHER.exe
中的另一个按钮下尝试了以下代码:
private void Button_Click_1(object sender, RoutedEventArgs e)
{
try
{
var filePath = string.Format("{0}{1}", Utility.ExePath, PART_PATH);
AppDomain newappdomain = getAppDomainForAssembly(filePath, "LOADED.exe.domain");
object loadedexe_object = getInstanceFromAppDomain(ref newappdomain, filePath);
//If you know the method name to call...
executeMethod(loadedexe_object.GetType(), "methodname", ref loadedexe_object, null);
//or get entry point...
executeMethod(loadedexe_object.GetType(),
_asm_resolve(filePath).EntryPoint.Name, ref loadedexe_object, null);
}
catch (Exception ex)
{
var type = "";
if (ex is ArgumentNullException)
{
type = "ArgumentNullException";
}
else if (ex is NotSupportedException)
{
type = "NotSupportedException";
}
else if (ex is AppDomainUnloadedException)
{
type = "AppDomainUnloadedException";
}
else if (ex is TypeLoadException)
{
type = "TypeLoadException";
}
else if (ex is MissingMethodException)
{
type = "MissingMethodException";
}
else if (ex is MethodAccessException)
{
type = "MethodAccessException";
}
else if (ex is BadImageFormatException)
{
type = "BadImageFormatException";
}
else if (ex is FileLoadException)
{
type = "FileLoadException";
}
MessageBox.Show(type + "\n\r\n\r" + ex.Message + "\n\r\n\r" + ex.InnerException + "\n\r\n\r" + ex.Source);
}
}
private AppDomain getAppDomainForAssembly(string assemblypath, string appdomainname)
{
//this._assembly_file = AssemblyFile;
string _assembly_file_name = System.IO.Path.GetFileName(assemblypath);
string _rootpath = System.IO.Path.GetDirectoryName(assemblypath);
//this._assembly_class_name = AssemblyClassNameToInstance;
AppDomainSetup _app_domain_info = new AppDomainSetup();
_app_domain_info.ApplicationBase = _rootpath;
_app_domain_info.PrivateBinPath = _rootpath;
_app_domain_info.PrivateBinPathProbe = _rootpath;
_app_domain_info.ConfigurationFile = _rootpath + @"LOADED.exe.config"; //Here put the path to the correct .assembly .config file
AppDomain _app_domain = AppDomain.CreateDomain(appdomainname, null, _app_domain_info);
return _app_domain;
}
protected System.Reflection.Assembly _asm_resolve(string assemblyFile)
{
return System.Reflection.Assembly.LoadFrom(assemblyFile);
}
private object getInstanceFromAppDomain(ref AppDomain appDomain,
string assemblyPath, string className = null)
{
if (string.IsNullOrEmpty(className))
{
System.Reflection.Assembly assembly = _asm_resolve(assemblyPath);
System.Reflection.MethodInfo method = assembly.EntryPoint;
// Now my ERROR is in this line>>
return appDomain.CreateInstanceFromAndUnwrap(assemblyPath, method.Name);
}
else
{
return appDomain.CreateInstanceFromAndUnwrap(assemblyPath, className);
}
}
private void Button_Click_2(object sender, RoutedEventArgs e)
{
var filePath = string.Format("{0}{1}", Utility.ExePath, PART_PATH);
IsolatedInvoker.Invoke(filePath, "Main", "Main", new object[] {});
}
现在我的错误在这一行:
好的
C)
我又搜索了一遍,找到了这个():
然后,我通过午餐程序.exe中另一个按钮下的以下代码调用它:
private void Button_Click_1(object sender, RoutedEventArgs e)
{
try
{
var filePath = string.Format("{0}{1}", Utility.ExePath, PART_PATH);
AppDomain newappdomain = getAppDomainForAssembly(filePath, "LOADED.exe.domain");
object loadedexe_object = getInstanceFromAppDomain(ref newappdomain, filePath);
//If you know the method name to call...
executeMethod(loadedexe_object.GetType(), "methodname", ref loadedexe_object, null);
//or get entry point...
executeMethod(loadedexe_object.GetType(),
_asm_resolve(filePath).EntryPoint.Name, ref loadedexe_object, null);
}
catch (Exception ex)
{
var type = "";
if (ex is ArgumentNullException)
{
type = "ArgumentNullException";
}
else if (ex is NotSupportedException)
{
type = "NotSupportedException";
}
else if (ex is AppDomainUnloadedException)
{
type = "AppDomainUnloadedException";
}
else if (ex is TypeLoadException)
{
type = "TypeLoadException";
}
else if (ex is MissingMethodException)
{
type = "MissingMethodException";
}
else if (ex is MethodAccessException)
{
type = "MethodAccessException";
}
else if (ex is BadImageFormatException)
{
type = "BadImageFormatException";
}
else if (ex is FileLoadException)
{
type = "FileLoadException";
}
MessageBox.Show(type + "\n\r\n\r" + ex.Message + "\n\r\n\r" + ex.InnerException + "\n\r\n\r" + ex.Source);
}
}
private AppDomain getAppDomainForAssembly(string assemblypath, string appdomainname)
{
//this._assembly_file = AssemblyFile;
string _assembly_file_name = System.IO.Path.GetFileName(assemblypath);
string _rootpath = System.IO.Path.GetDirectoryName(assemblypath);
//this._assembly_class_name = AssemblyClassNameToInstance;
AppDomainSetup _app_domain_info = new AppDomainSetup();
_app_domain_info.ApplicationBase = _rootpath;
_app_domain_info.PrivateBinPath = _rootpath;
_app_domain_info.PrivateBinPathProbe = _rootpath;
_app_domain_info.ConfigurationFile = _rootpath + @"LOADED.exe.config"; //Here put the path to the correct .assembly .config file
AppDomain _app_domain = AppDomain.CreateDomain(appdomainname, null, _app_domain_info);
return _app_domain;
}
protected System.Reflection.Assembly _asm_resolve(string assemblyFile)
{
return System.Reflection.Assembly.LoadFrom(assemblyFile);
}
private object getInstanceFromAppDomain(ref AppDomain appDomain,
string assemblyPath, string className = null)
{
if (string.IsNullOrEmpty(className))
{
System.Reflection.Assembly assembly = _asm_resolve(assemblyPath);
System.Reflection.MethodInfo method = assembly.EntryPoint;
// Now my ERROR is in this line>>
return appDomain.CreateInstanceFromAndUnwrap(assemblyPath, method.Name);
}
else
{
return appDomain.CreateInstanceFromAndUnwrap(assemblyPath, className);
}
}
private void Button_Click_2(object sender, RoutedEventArgs e)
{
var filePath = string.Format("{0}{1}", Utility.ExePath, PART_PATH);
IsolatedInvoker.Invoke(filePath, "Main", "Main", new object[] {});
}
但我得到了与前面方法相同的错误**B**
:
中发生类型为“System.TypeLoadException”的未处理异常
午餐程序
其他信息:无法从程序集加载类型“Main”
已加载,版本=1.0.0.0,区域性=中性,
PublicKeyToken=null'
D)
我还在午餐程序.EXE中的另一个按钮下进行了这种测试:
private void Button_Click_3(object sender, RoutedEventArgs e)
{
var filePath = @"D:\LOADED.exe";
var dll = File.ReadAllBytes(filePath);
var assembly = Assembly.Load(dll);
var app = typeof (Application);
var field = app.GetField("_resourceAssembly", BindingFlags.NonPublic | BindingFlags.Static);
field.SetValue(null, assembly);
//fix urihelper
var helper = typeof (BaseUriHelper);
var property = helper.GetProperty("ResourceAssembly", BindingFlags.NonPublic | BindingFlags.Static);
property.SetValue(null, assembly, null);
//---- Now my ERROR is in this line >>
assembly.EntryPoint.Invoke(null, new object[] {});
}
在运行时的最后一行代码中出现错误:
类型的未处理异常
mscorlib.dll中发生了“System.Reflection.TargetInvocationException”
其他信息:异常已由的目标引发
调用。
最后:
我糊涂了
- 以上所有方法中我的错误是什么
- 为什么所有的方法都以错误告终
请帮助我简单描述和一些代码,因为我是这个场景的初学者(加载程序集、创建AppDomain
和…),但我需要将WPF应用程序加载到内存并显示其窗口,然后在内存中运行时从H.D.D删除其文件
创建共享程序集。这将加载到两个AppDomain(“启动器”域、“加载”域)中,并作为“加载”AppDomain的入口点:
添加新项目>类库>名称:ChildDomainLoader
向新项目添加以下引用:System.Xaml
,WindowsBase
,PresentationFramework
在启动器
项目中为ChildDomainLoader
添加项目引用。不必修改加载的
项目
向共享程序集添加一些代码。我们需要一个可以跨域调用并加载子程序集的MarshallByRefObject。我们将其称为Runner
:
using System;
using System.IO;
using System.Linq;
using System.Reflection;
using System.Windows;
namespace ChildDomainLoader
{
public class Runner : MarshalByRefObject
{
public static AppDomain RunInOtherDomain(string assemblyPath)
{
var ownType = typeof (Runner);
string ownAssemblyName = ownType.Assembly.FullName;
// Create a new AppDomain and load our assembly in there.
var childDomain = AppDomain.CreateDomain(Guid.NewGuid().ToString());
childDomain.Load(ownAssemblyName);
// Call Run() in other AppDomain.
var runner = (Runner) childDomain.CreateInstanceAndUnwrap(ownAssemblyName, ownType.FullName);
runner.Run(assemblyPath);
return childDomain;
}
public void Run(string assemblyPath)
{
// We load the assembly as byte array.
var otherAssemblyBytes = File.ReadAllBytes(assemblyPath);
var assembly = AppDomain.CurrentDomain.Load(otherAssemblyBytes);
AppDomain.CurrentDomain.AssemblyResolve += (sender, args) =>
{
throw new NotImplementedException("Probably need to do some work here if you depend on other assemblies.");
};
// Set the assembly as ResourceAssembly, as WPF will be confused otherwise.
Application.ResourceAssembly = assembly;
// Search for the App class.
var app = assembly
.GetExportedTypes()
.Single(t => typeof(Application).IsAssignableFrom(t));
// Invoke its Main method.
MethodInfo main = app.GetMethod("Main", BindingFlags.Static | BindingFlags.Public);
main.Invoke(null, null);
}
}
}
使用它。从启动程序应用程序调用Runner.RunInOtherDomain
var assemblyPath = "path to your loaded.exe";
ChildDomainLoader.Runner.RunInOtherDomain(assemblyPath);
File.Delete(assemblyPath);
我建议您缩小问题(目前它看起来更像是一个应用程序开发的请求),并指定代码的主要部分导致问题。诚挚的问候,您也可以考虑使用Surrun.St.(启动)启动启动程序的另一个应用程序。这里描述的方法:我知道process.start,但我想在运行后删除exe文件!!!这个问题有一些示例,而且很长,但我的要求很简单,答案不会很大!非常感谢:D…您的说明非常有效!当然,在我关闭LOADED.exe
后会删除文件,因为午餐者加载程序等待加载结束以继续。因此,我向RunInOtherDomain和Run方法添加了一个bool参数,以检测是否也必须删除程序集,然后我添加了以下代码以在加载程序集后运行:if(forceDeleteAssembly&&File.Exists(assemblyPath))File.delete(assemblyPath);
现在一切正常:)
