Question

I have a method that uses a list which I need to pass into it.

Depending on where I call this method the type of the list is different.

Is it possible to pass the list in as a generic list and then cast it to a certain type, or do I need to create parameters for every type of list that can be used (see below)?

public string MyMethod(List<Type1> list1, List<Type2> list2, ...etc )
    {
      switch(someCondition)
        {
          case 1:
           //pass list1 into a method from class1
          break;
          case 2: 
           //pass list2 into a method from class2
         break;

          ...//etc for several more lists
        }

Answer 1

Instead of making a single method with multiple parameters, why don’t you make several methods with a single List type? It seems you are not sharing much code from one List type to another anyway.

public string MyMethod(List<int> list)
{
  //do something with list
}

public string MyMethod(List<bool> list)
{
  //do something with list1
}
...
