ReferenceEquals - >Determines whether the specified System.Object instances are the same instance.

public bool IsNull(object obj)
{   
   return object.ReferenceEquals(obj, null);
}

To test above method:-

string st = null;
Response.Write(IsNull(st) + "<br/>"); 
True             
st = "1";
Response.Write(IsNull(st) + "<br/>"); 
False
