我希望能够自动附加调试器，例如：System.Diagnostics.Debugger.Launch()，而不是当前进程到另一个命名进程。我有一个进程名称和PID来识别其他进程。
这可能吗？

修改
GSerjo提供了正确的解决方案。我想就如何改进它（和解释）分享一些想法。我希望我的改进答案对遇到同样问题的其他人有用。
Processes。Debug。或者，在Visual Studio中，选择Debug > Attach to Process...。
结果将取决于您是否有权访问源代码。
请注意：以下代码在某些意义上是脆弱的， 例如Visual Studio版本号，是硬编码的。请记住这一点 如果您打算发布您的计划。
首先，在项目中添加对EnvDTE的引用（右键单击解决方案资源管理器中的references文件夹，添加引用）。在下面的代码中，我将只显示不寻常的using指令;省略了using System等普通的。
由于您是interacting with COM，因此您需要确保使用STAThreadAttribute修饰Main方法（应用程序的入口点）。
然后，您需要define the IOleMessageFilter Interface，这将允许您与定义的COM方法进行交互（请注意ComImportAttribute）。我们需要访问消息过滤器，以便我们可以在Visual Studio COM组件阻止其中一个调用时重试。
using System.Runtime.InteropServices;
[ComImport, Guid("00000016-0000-0000-C000-000000000046"), InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]
public interface IOleMessageFilter
{
[PreserveSig]
int HandleInComingCall(int dwCallType, IntPtr hTaskCaller, int dwTickCount, IntPtr lpInterfaceInfo);
[PreserveSig]
int RetryRejectedCall(IntPtr hTaskCallee, int dwTickCount, int dwRejectType);
[PreserveSig]
int MessagePending(IntPtr hTaskCallee, int dwTickCount, int dwPendingType);
}
现在，我们需要实现此接口以处理传入的消息：
public class MessageFilter : IOleMessageFilter
{
private const int Handled = 0, RetryAllowed = 2, Retry = 99, Cancel = -1, WaitAndDispatch = 2;
int IOleMessageFilter.HandleInComingCall(int dwCallType, IntPtr hTaskCaller, int dwTickCount, IntPtr lpInterfaceInfo)
{
return Handled;
}
int IOleMessageFilter.RetryRejectedCall(IntPtr hTaskCallee, int dwTickCount, int dwRejectType)
{
return dwRejectType == RetryAllowed ? Retry : Cancel;
}
int IOleMessageFilter.MessagePending(IntPtr hTaskCallee, int dwTickCount, int dwPendingType)
{
return WaitAndDispatch;
}
public static void Register()
{
CoRegisterMessageFilter(new MessageFilter());
}
public static void Revoke()
{
CoRegisterMessageFilter(null);
}
private static void CoRegisterMessageFilter(IOleMessageFilter newFilter)
{
IOleMessageFilter oldFilter;
CoRegisterMessageFilter(newFilter, out oldFilter);
}
[DllImport("Ole32.dll")]
private static extern int CoRegisterMessageFilter(IOleMessageFilter newFilter, out IOleMessageFilter oldFilter);
}
我将返回值定义为常量以获得更好的可读性，并重构整个事情以消除MSDN示例中的一些重复，所以我希望你会发现它不言自明。 extern int CoRegisterMessageFilter是我们与非托管邮件过滤器代码的连接 - 您可以read up on the extern keyword at MSDN。
现在剩下的就是一些说明用法的代码：
using System.Runtime.InteropServices;
using EnvDTE;
[STAThread]
public static void Main()
{
MessageFilter.Register();
var process = GetProcess(7532);
if (process != null)
{
process.Attach();
Console.WriteLine("Attached to {0}", process.Name);
}
MessageFilter.Revoke();
Console.ReadLine();
}
private static Process GetProcess(int processID)
{
var dte = (DTE)Marshal.GetActiveObject("VisualStudio.DTE.10.0");
var processes = dte.Debugger.LocalProcesses.OfType<Process>();
return processes.SingleOrDefault(x => x.ProcessID == processID);
}

更简单的方法。
public static void Attach(DTE2 dte)
{
var processes = dte.Debugger.LocalProcesses;
foreach (var proc in processes.Cast<EnvDTE.Process>().Where(proc => proc.Name.IndexOf("YourProcess.exe") != -1))
proc.Attach();
}
internal static DTE2 GetCurrent()
{
var dte2 = (DTE2)Marshal.GetActiveObject("VisualStudio.DTE.12.0"); // For VisualStudio 2013
return dte2;
}
用法：
Attach(GetCurrent());

选项是运行; vsjitdebugger.exe -p ProcessId
可以使用Process.Start在c＃app中执行此操作。
