Checking Return Values Without Saving Them
Often times I will be debugging some code and I want to see a return value of a function; but the value of the function is not saved into a variable for one reason or another.
In the simplest form you can see this scenario in the following code:
1: using System;
2: using System.Collections.Generic;
3: using System.Linq;
4: using System.Text;
6: namespace Test
8: class Program
10: static int Foo()
12: return 4;
15: static void Main(string args)
If I want to see the value that is returned from the function call to Foo(), I can start by setting a breakpoint on line 18. Then I go to the menu bar and follow the path 'Debug'->'Windows'->'Registers'. You can see that the EAX register will contain the return value even though I didn't save the return value to a variable.
