my debugger screen is grey, I tried to do this....but I couldnt

hello guys, i have to write a simple project ... it is a hangman code in C# i have this...but when I run it... i keeps printing twice some sentences... if anybody can help me... and if the user type something different from l ..when it is asked...everything goes wrong...
