Get Static method and invoke it 
On the other hand, if the method is static, you do not need an instance to call it. 
var method = typeof(Math).GetMethod("Exp"); 
var result = method.Invoke(null, new object[] {2});//Pass null as the first argument (no need for an 
instance) 
Console.WriteLine(result); //You'll  get  e^2 
Output:
