Checking type of parameter

Question

I would like to check, which type a parameter of a method has, in order to give the variable I determine inside the method with the wished type:

public static Object getFileContent(String filename, Type returntype)
{
     if (returntype.GetType().Equals(string))
     {
       // do something
     }
}

This doesn't work. What could I do, to check if returntype is string or List<string>?

Answer 1

returntype == typeof(string)

No need to call GetType because you already have a type. (GetType would not return a useful answer anyway, it would return typeof(Type)).
