Other than setting a debug variable and incrementing it every time you start the foreach, when you break in with the Visual Studio debugger connected, is there a way to tell that this is the Xth time through the loop?
I guess this would be a feature of Visual Studio if anything, not something that would be added to the compiled code.

There is no foreach in C. You can use a for loop to loop through the data but the length needs to be know or the data needs to be terminated by a know value (eg. null).
The forloop is faster than the foreach loop if the array must only be accessed once per iteration.
Set a breakpoint inside the loop, then right click on the breakpoint to set the conditions. You can also right click to see the hit count while debugging and reset it if you want. You can set a boolean expression that is evaluated when the breakpoint hits to conditionally break (or just pass over).

You can also use Visual Studio's Immediate Window, which allows you to write C# expressions against any variables in scope while debugging. Use the List.IndexOf() method, like so:
