c# - Getting a Method's Return Value in the VS Debugger

Question

Is it possible to get a method's return value in the Visual Studio debugger, even if that value isn't assigned to a local variable? For example, I'm debugging the following code:

public string Foo(int valueIn)
{
    if (valueIn > 100)
        return Proxy.Bar(valueIn);
    else
        return "Not enough";
}

Since I'm not setting any local variables in Foo, and assuming I'm not setting a break point in whatever's calling Foo, is there a way to see what the return value is if I have a breakpoint inside of Foo (or another way)? I don't have much experience with the Autos or Intermediate windows, so I'm not sure if those are even a valid option or not.

Answer 1

You can set a breakpoint in Foo, open the immediate window and run the following command:

? Foo(valueIn)

This will print the return value in the Immediate Window.

You can also copy the expression and paste it into the Watch window, though I would do this only if I am certain that the call has no side effects (otherwise you can get confusing results).
