Resolved CS8600 error on numerous lines

[C# learner]

I recently installed Community Visual Studio from Enterprise Visual Studio. I found that when I am using Community Visual Studio that I keep getting a CS8600 error on numerous lines of code. I know it has something to do with null but don't know how to resolve the issue. Here is an example:

while ((line = sr.ReadLine()) != null)

The sr.ReadLine is underlined green and giving me a CS8600 error. How do I resolve this issue?

Maybe you could provide the error message, given that you have it right in front of you, rather than requiring each of us to look it up for ourselves.

Ok , I found the answer. I had the line variable as a string. I changed it to var. That worked.
