Breakpoint in C #

I have a problem with breakpoints, when I insert a breakpoint and run the program, it hits the breakpoint. But a system showing the parse code instead of my code can help me how to fix it? I have been struggling for almost 2 hours, please help me, I am using MS.Visual Studio 2005. here is a snapshot of the disassembly.

I tried to open debug and didn't give me the option to disable this, thanks in advance
