C# 如何跟踪排序后的方法调用?
我想按照顺序跟踪方法调用。因为日志记录将应用于生产,所以我不想对代码进行太多修改 到目前为止,我想在Unity上应用一个拦截器来跟踪方法调用,我几乎完成了。然而,日志打印出来并不是我所期望的。我需要的是: 来自peusedo代码,如下所示:C# 如何跟踪排序后的方法调用?,c#,.net,unity-interception,C#,.net,Unity Interception,我想按照顺序跟踪方法调用。因为日志记录将应用于生产,所以我不想对代码进行太多修改 到目前为止,我想在Unity上应用一个拦截器来跟踪方法调用,我几乎完成了。然而,日志打印出来并不是我所期望的。我需要的是: 来自peusedo代码,如下所示: void method1() { call method2(); } static void Main(string[] args) { var container = new UnityContain

}

}
public int Order { get; set; }
}
跟踪日志的格式应如下所示:
正在输入方法调用1/
输入方法调用2
离开方法调用2/
离开方法调用1
顺便说一句,我的应用程序运行在.NETFramework版本4上
计划如下:
void method1()
{
call method2();
}
static void Main(string[] args)
{
var container = new UnityContainer();
container.RegisterType<IInterface1, Implementation1>();
container.RegisterType<IInterface2, Implementation2>();

container.Configure<Interception>()
.SetInterceptorFor<IInterface1>(new InterfaceInterceptor());
container.Configure<Interception>()
.SetInterceptorFor<IInterface2>(new InterfaceInterceptor());
var service = container.Resolve<IInterface1>();
var results = service.GetListCustomerIdByName("abc");
Console.ReadLine();
}

if (result.Exception != null)
{
Console.WriteLine("Exception: {0}", result.Exception);
}
Console.WriteLine("Leaving

return result;

对不起,我的密码。它相当长 这里有一个类提供了该功能:
class Scope : IDisposable
{
Action<string> _logger;
string _memberName;
public Scope(Action<string> logger, [CallerMemberName] string memberName = "N/A")
{
if (logger == null) throw new ArgumentNullException();
_logger = logger;
_memberName = memberName;
_logger(string.Format("Entered {0}", _memberName));
}
public void Dispose()
{
_logger(string.Format("Exited {0}", _memberName));
}
}
注意:如果使用不支持[CallerMemberName]
属性的早期版本的C#,则必须显式提供memberName
您还可以使用我在.NET 4.5之前的版本中使用的这个帮助器类:
public static class Here
{
public static string Spot(HereOptions options)
{
return MakeMessageInternals(options, 3);
}
public static string Type
{
get
{
return MakeMessageInternals(HereOptions.Type, 3);
}
}
public static string Member
{
get
{
return MakeMessageInternals(HereOptions.Member, 3);
}
}
public static string FileLine
{
get
{
return MakeMessageInternals(HereOptions.FileLine, 3);
}
}
public static string FileName
{
get
{
return MakeMessageInternals(HereOptions.FileName, 3);
}
}
static StackFrame GetCaller(int index) { return new StackTrace(true).GetFrame(index); }
static string MakeMessageInternals(HereOptions options, int index)
{
StackFrame first = null;
var _FileName = new StringBuilder();
var _FileLine = new StringBuilder();
var _Member = new StringBuilder();
var _Type = new StringBuilder();
if ((options & HereOptions.FileName) == HereOptions.FileName)
{
first = GetCaller(index);
if (first != null)
{
var fn = first.GetFileName();
if (!string.IsNullOrEmpty(fn))
_FileName.Append(" " + Path.GetFileName(fn));
}
}
if ((options & HereOptions.FileLine) == HereOptions.FileLine)
{
if (first == null)
first = GetCaller(index);
if (first != null)
{
var ln = first.GetFileLineNumber();
_FileLine.Append(" #" + ln);
}
}
if ((options & HereOptions.Member) == HereOptions.Member)
{
if (first == null)
first = GetCaller(index);
if (first != null)
{
var mn = first.GetMethod().Name;
_Member.Append(" " + mn);
}
}
if ((options & HereOptions.Type) == HereOptions.Type)
{
if (first == null)
first = GetCaller(index);
if (first != null)
{
var dt = first.GetMethod().DeclaringType;
_Type.Append(string.Format(" ({0})", dt));
}
}
var messageInternal = string.Format("{0}{1}{2}{3}",
_FileName,
_FileLine,
_Member,
_Type).Trim();
return messageInternal;
}
}
[Flags]
public enum HereOptions : byte
{
None = 0,
FileName = 1,
FileLine = 2,
Member = 4,
Type = 8,
All = 15
}
这意味着每次方法调用,我都会使用(范围记录器…我不确定如果里面有许多嵌套方法调用,它是否会打印出正确的方法调用顺序。无论如何,感谢您的努力。只要您不进行并行编程,它将打印出正确的方法调用,无论嵌套调用有多深。我自己使用了这个类的更复杂版本。我确实使用过没有找到更好的方法(有一种方法:使用PostSharp并使用面向方面的编程;但我不喜欢它)。对不起,我很失望!:)我不应用您的答案的另一个原因是您的代码仅适用于.Net framework 4.5版。我的代码运行在.Net framework 4.5版上。顺便说一句,我将+1,因为您的答案可能会有人从您的答案中得到帮助。我根据您的答案找出解决方法。我找到了解决CallerMemberName功能的链接。非常感谢您的帮助你的想法。我会接受这是一个正确的答案。我已经有了一个工具。我已经添加到了答案中。
