How do I debug C# errors in my application?

I'm getting a NullReferenceException in my C# application. How can I debug this?

A NullReferenceException usually means you're trying to access an object that hasn't been initialized. Check your code for any variables that might be null.

I think it's happening in a method where I'm using a list. How can I check if the list is null?

You can use an if statement to check if the list is null before accessing it. For example: if(myList != null) { // access the list }.

What if the list is initialized but still empty?

If the list is initialized but empty, you can check its count using myList.Count. If it's 0, then it's empty, and you should handle that case accordingly.

Thanks! That helps a lot. Any tips for general debugging in C#?

Sure! Use breakpoints in Visual Studio, check the call stack, and make use of logging to track down issues.
