Question

May 19 2007 Hi Guys I have a confusion in understanding “ signature and parameter”. The sentence says that “The delegate and method is having the same signature and parameters type” public delegate double Delegate_Prod( int a int b); static double fn_Prodvalues( int val1 int val2) I have given two codes obtained from the same program. Please anybody explain me what is meant by signature and parameter. Thank you

Hi The signature of a delegate/function is determined by its return type and the type and order of the parameters the function/delegate contains. In your case you have a return value of double for both the delegate and the function. Also you have two parameters in the delegate and the function and they are both of type int. So you can conclude that they have both the same signature and parameters type. Little summary : Return type : double Parameters : (int a int b) and (int val1 int val2) The parameters name does not matter to the signature only their type and orders. Simon
