Hello,

I have a method called public int sum(int a,int b).

And i had made use of the sum() method in all other pages in my project.

But now i wanted to add one new parameter called int c i.e., sum(int a,int b,int c).

If i add it them i am getting error that

"

VB

Error   2   No overload for method 'sum' takes 4 arguments    C:\Windows Data\gv_info\contactus.aspx.cs   43  28  C:\Windows Data\gfo\

The error message is quite clear. You don't have a sum method or a overload sum method to deal with 4 parameters.

Either change the existing sum method signature or define one overload of sum method accepting 4 parameters.

Solution 2

In C# (provided it's V4 or above) you can provide optional arguments:

C#

public int Sum(int a, int b, int c = 0)
   {
   ...

And it'll work fine.

Or, you could use the params keyword:

C#

public int Sum (params int[] vars)
   {
   int sum = 0;
   foreach (int i in vars)
      {
      sum += i;
   ...

You can then call it with one or more values:

C#

sum = Sum(7);
sum = Sum(1, 2, 3, 4, 5, 6, 7, 8, 9);

HI..

i am sorry i am dealing with specific function or method like

public int getData(int id,int regid,int CRN_id,int cust_id)
{

// get the id
// do some calculation
//update the table with CRN

///finally delete cust_id from table
....
....
return result;
}

In this case
