Problems with C#

Debugging is a skill that can't really be taught. It's learnt by doing. Everybody who programs develops their own debugging strategies, sometimes using the debugger and sometimes just by using print statements to print large amounts of program state (variable values) to the console and then glancing through the list to see if you can see where it went wrong, and then working from there. The specific ways that you go about debugging though using these general techniques, you'll have to figure out by yourself. Sometimes it depends on what the program is as to what the best debugging technique is. A combination of methodical and creative thinking is the key.

And to be blunt, if you can't debug, you can't program properly. If you are unwilling to debug, programming is not for you and you should find something else to do.
