C# 在另一个用户下启动流程';国书
我想用另一个用户名的凭据启动一个进程。 这就是我现在拥有的:C# 在另一个用户下启动流程';国书,c#,windows,C#,Windows,我想用另一个用户名的凭据启动一个进程。 这就是我现在拥有的: /// <summary> /// Do actions under another username's credentials /// </summary> /// <param name="username">Username to inpersonate</param> /// <param n

答案是对的,我们得到了“哑巴”
我们可以让它变得更简单:
public static void Run()
{
try
{
const string file = "cmd.exe";
var sspw = new SecureString();
foreach (var c in "pass1234/")
sspw.AppendChar(c);
var proc = new Process();
proc.StartInfo.UseShellExecute = false;
proc.StartInfo.WorkingDirectory = Path.GetDirectoryName(file);
proc.StartInfo.FileName = Path.GetFileName(file);
proc.StartInfo.Domain = "WIN08";
proc.StartInfo.Arguments = "";
proc.StartInfo.UserName = "dummy";
proc.StartInfo.Password = sspw;
proc.StartInfo.LoadUserProfile = false;
proc.Start();
}catch(Exception e)
{
Console.WriteLine(e);
}
但是,我仍然有例外…我认为您不需要登录用户并复制句柄。您只需在ProcessStartInfo对象中设置用户名、域和密码。如果我没记错的话,那是从.NET3.0开始提供的 编辑:
另外,有关更多信息,当您将用户名/域/密码提供给ProcessStartInfo:时,会发生以下情况:。拒绝访问的原因可能是您无权访问用户的桌面或WindowsStation。仅仅给LoginUser打电话是不够的。对某些人来说这可能会很奇怪,我很抱歉,我是Linux开发者。。。 测试:
//
///类,该类处理另一个用户名凭据
///
类凭据
{
///
///运行方式使用的SecureString密码的构造函数
///
///普通密码
///SecureString密码
私有静态SecureString MakeSecureString(字符串文本)
{
SecureString secure=新的SecureString();
foreach(文本中的字符c)
{
安全的。附加字符(c);
}
安全返回;
}
///
///使用其他用户凭据运行应用程序。
///工作目录设置为C:\Windows\System32
///
///可执行文件的完整路径
///所需凭据的用户名
///所需凭据的密码
公共静态无效运行方式(字符串路径、字符串用户名、字符串密码)
{
尝试
{
ProcessStartInfo myProcess=新的ProcessStartInfo(路径);
myProcess.UserName=用户名;
myProcess.Password=MakeSecureString(密码);
myProcess.WorkingDirectory=@“C:\Windows\System32”;
myProcess.UseShellExecute=false;
Process.Start(myProcess);
}
捕获(Win32Exception w32E)
{
//这个过程没有开始。
控制台写入线(w32E);
}
}
}
您可能忘记设置只读安全字符串?我的方法很适合我:
Process proc = new Process
{
StartInfo =
{
CreateNoWindow = true,
UseShellExecute = false,
RedirectStandardOutput = true,
RedirectStandardInput = true,
FileName = "cmd.exe",
UserName = "user",
Domain = "myDomain",
Password = GetSecureString("Password"),
Arguments = "/c ipconfig"
}
};
proc.Start();
GetSecureString()函数:
public static SecureString GetSecureString(string str)
{
SecureString secureString = new SecureString();
foreach (char ch in str)
{
secureString.AppendChar(ch);
}
secureString.MakeReadOnly();
return secureString;
}
您执行此应用程序的凭据是什么?管理员试图在标准用户下运行应用程序。您是否可以右键单击exe并选择“运行方式…”?是否有完整源代码示例的最终解决方案?
Process proc = new Process
{
StartInfo =
{
CreateNoWindow = true,
UseShellExecute = false,
RedirectStandardOutput = true,
RedirectStandardInput = true,
FileName = "cmd.exe",
UserName = "user",
Domain = "myDomain",
Password = GetSecureString("Password"),
Arguments = "/c ipconfig"
}
};
proc.Start();
public static SecureString GetSecureString(string str)
{
SecureString secureString = new SecureString();
foreach (char ch in str)
{
secureString.AppendChar(ch);
}
secureString.MakeReadOnly();
return secureString;
}
