Hi mohit818 try this code 

The partial methods cannot have mutliple declarations. 

With a partial class you extend an existing class.  you don't have the declare validate and parameter method in the partial class

Answer 2

After fixing the syntax of Main function, the partial methods seem to work, i.e. the custom implementation of validate and parameter is executed. Give some details about the issue.
