How to test data type in C# application ?

Hi all

How we could test data type in C# application ? which is like, if variable a = string, variable b = int, then variable c = class (instantiate = new class)

How can I determine/test early process for a and b that a = string and b = int?

It's the sample like this : int count = 0
How can i check that count is = integer (data type) ?

Thank you, your response will be appreciate

Use the "is" operator. For instance:

if(count is int) {  }
