如何在 Visual Studio 中将进程附加到调试器？

Question

I know I can start a process in code with Process.Start() . Is it also possible to attach the debugger to that process?

Not from code per se , but just a way to do it?

Answer 1

You can attach to a running process using Tools | Attach to Process Tools | Attach to Process . If it's a Web Application, you can attach to it by attaching to aspnet_wp.exe or w3wp.exe .

To answer your question on how to attach to a process programmatically:

• Attaching to a Process Using VS.NET Automation Model

Here are other Stack Overflow questions that deal with that:

• Communicating with the Visual Studio Debugger Programmatically?
• Programmatically apply breakpoints in Visual Studio

Answer 2

In visual studio click Tools | Attach to process. Then select appropriate service.

Answer 3

You can do this in pretty much any debugger worth its salt.

Visual Studio has one that should fit your needs.

If you need a little more advanced control, try OllyDbg , which is a disassembler, so you can actually manipulate your program at the assembly level. This will give you complete control, but it might be information overload as well.

Answer 4

In Visual Studio 2015, click 'Debug > Attach to process' in the menu. Alternatively, there is a shortcut key Ctrl+Alt+P.

Answer 5

You can do this in your code.

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;
        }

Usage:

Attach(GetCurrent());
