.net - C# testing to see if a string is an integer?

Question

I'm just curious as to whether there is something built into either the C# language or the .NET Framework that tests to see if something is an integer

if (x is an int)
   // Do something

It seems to me that there might be, but I am only a first-year programming student, so I don't know.

Use the int.TryParse method.

string x = "42";
if(int.TryParse(x, out int value))
  // Do something

If it successfully parses it will return true, and the out result will have its value as an integer.
