Variable is assigned but its value is never used (C#)

Question

In Visual Studio I used the following code:

 private bool answer = true;
    Private Buttonclick()
   {
      if()
       {
        answer =false
        }
          


        

Answer 1

In addition to the answers above, for more deep understanding of the this warning:

This warning will not always pop-up (if you not use assigned variable). Assigning a non-constant expression or method result will NOT generate the warning. It is done intentionally, since such an unassigned variables can be used in debugging.

For example:

 var answer = SomeObject.SomePropery; //will not generate CS0219

There are excellent explanation in Microsoft.Docs: https://docs.microsoft.com/en-us/dotnet/csharp/misc/cs0219
