C# Action/Function List

Question

I have a program that has to execute a function acording to a Enum and I\'m wondering If there\'s another way to it than this:

enum FunctionType
{
 Addition = 0,         


        

Answer 1

If your functions contain same signature then you can do something like this

enum FunctionType
{
 Addition = 0,
 Substraction = 1,
 Mutiplication = 2,
 Division = 3
}
void ExecuteFunction(FunctionType Function)
{
  //variable will contain function to execute
  public Func functionToExecute= null;

  switch(Function)
  {
    case FunctionType.Addition: functionToExecute=Addition;
    break;
    case FunctionType.Substraction: functionToExecute=Subsctration;
    break;      
    ...
    default: ...  
  }

  //Checking if not reached default case
  if(functionToExecute!=null)
  {
   var result= functionToExecute(para1,para2);
   ...............
  }


}
