A delegate can point to multiple methods but all these methods must have same signature as the delegate. Have you written a single delegate and ten methods. These ten methods do they have to be called from the same delegate.
If yes then when you instantiate the different instances of the delegate you need to pass the method you want to call while instantiating. Then call the invoke method to call the respective method.

1. Initialize the delegate.
2. Create Method(functions)
3. Point the Function through the delegate.
Following sample code will give your more information.

public delegate double Delegate_Multi(int a,int b);
class Class1
{
static double MultiplayvaluesFN(int val1,int val2)
{
return val1*val2;
}
static void Main(string[] args)
{
//Creating the Delegate Instance
Delegate_Multi delObj = new Delegate_Multi(MultiplayvaluesFN);
Console.Write("Please Enter Values");
int v1 = Int32.Parse(Console.ReadLine());
int v2 = Int32.Parse(Console.ReadLine());
//use a delegate for processing
double res = delObj(v1,v2);
Console.WriteLine ("Result :"+res);
Console.ReadLine();
}
}

Whenever we want to create delegate methods we need to declare with delegate keyword and delegate methods signature should match exactly with the methods which we are going to hold like same return types and same parameters otherwise delegate functionality won't work if signature not match with methods
see below sample
write a delegate in class
you can create a class object and add reference of that class in asp.net and then by creating object of that class you can call it in asp.net
Thanks

write a delegate in class
public delegate int Delegatmethod(int a,int b);
public class Sampleclass
{
public int Add(int x, int y)
{
return x + y;
}
public int Sub(int x, int y)
{
return x + y;
}
}
you can create a class object and add reference of that class in asp.net and then by creating object of that class you can call it in asp.net
