如何在Visual Studio 2010中有条件地执行一行？

Question

I'd like the line to execute when running within Visual Studio but not when the exe is running stand alone.

Thanks.

Answer 1

Do you mean when a debugger is attached? If so, you could do something like this:

#if DEBUG
if (Debugger.IsAttached)
{
    //Your code here
}
#endif

This will only run when the debugger is attached, such as running with F5. Double clicking it or using Ctrl+F5 won't cause the if statement to be hit. It's also wrapped in a conditional so then when you compile to release the code is not even there.

Answer 2

You could use the build flags

#if DEBUG
      //do something in here
#endif

And then when you build in release those things won't happen.

Answer 3

You can use ConditionalAttribute . Put the code you want to execute conditionally in a method, and mark the method with [Conditional("DEBUG")] . The method and the call to it will only be compiled when the DEBUG constant is set.

Answer 5

I think this code may help:

[Conditional("DEBUG")]
private void DEBUG_Execute() 
{ 
    if (Debugger.IsAttached)
    { 
        //todo:  execute line when running within VS
    } 
} 

Answer 6

You can check the Application.startuppath

If you are in Debugging, that means bin/Debug folders are present otherwise you are running the exe. In this way you can formulate the code.
