Generic Methods

These are declared with a type parameter

Method_Name<T> (System.Generics.List<T> mylist) 

This is an example of a Generic Method Definition.
The "T" is a type parameter that is used as a placeholder for any type.
This data type can be specified when the method is called.

protected T Method_Name<T>(System.Func<bool, T> Method_ToRun, string Arg1) 
{ 
   return Method_ToRun(false) 
} 

Swap_Values

This method will swap the values of two generic types.

public class GenericMethods 
{ 
   public static void Swap_Values<T>( 
      ref T value1, 
      ref T value2) 
   { 
      T temporary = value1; 
      value1 = value2; 
      value2 = temporary; 
   } 
} 

int mysize = 5; 
System.Collections.Generic.Stack<double> StackOne; 
System.Collections.Generic.Stack<double> StackTwo; 

StackOne = new System.Collections.Generic.Stack<double>(mysize); 
StackTwo = new System.Collections.Generic.Stack<double>(mysize); 

// this swaps the entire collections 
GenericMethods.Swap_Values<System.Collections.Generic.Stack<double>>(ref StackOne, ref StackTwo); 

double ValueOne = 1.2; 
double ValueTwo = 3.4; 

// this swaps the individual values 
GenericMethods.Swap_Values<double>>(ref ValueOne, ValueTwo);
