Is there an easy way to set conditional breakpoints in Visual Studio?

If I want to hit a breakpoint only when the value of a variable becomes something, how can I do it?

When you are using Express edition you can try this:

#if DEBUG
    if( fooVariable == true )
        System.Diagnostics.Debugger.Break();
#endif

if statement makes sure that in release build breakepoint will not be present.

You can control when and where a breakpoint executes by setting conditions. The condition can be any valid expression that the debugger recognizes. For more information about valid expressions, see Expressions in the debugger.

To set a breakpoint condition:

  1. Right-click the breakpoint symbol and select Conditions (or press Alt + F9, C). Or hover over the breakpoint symbol, select the Settings icon, and then select Conditions in the Breakpoint Settings window.

    You can also set conditions in the Breakpoints window by right-clicking a breakpoint and selecting Settings, and then selecting Conditions.

  1. In the dropdown, select Conditional Expression, Hit Count, or Filter, and set the value accordingly.

  2. Select Close or press Ctrl+Enter to close the Breakpoint Settings window. Or, from the Breakpoints window, select OK to close the dialog.

Breakpoints with conditions set appear with a + symbol in the source code and Breakpoints windows.
