Pass parameter dynamically

Question

See more:

I have to pass the list to below function.

C#

public static List<List<T>> AllCombinationsOf<T>(params List<T>[] sets)
{ 
      //some set of code here
}

Now I call the function by using:

C#

var x = AllCombinationsOf(A,B,C);

I don't know the number of list that I need to pass before runtime. It will be change dynamically. How to I create the list dynamically and pass this function.

If I want to pass parameter to "AllCombinationsOf" as

C#

AllCombinationsOf(A,B,C,D); 
AllCombinationsOf(A,B);
AllCombinationsOf(A,B,C,D,E);

means what I have to do?

I have to pass parameter as dynamically( parameter that will be change)

I tried to add list into this

C#

List<List<string>> lst = new List<List<string>>();

but it not working

You need to clarify what you mean by "dynamically." Is the purpose of your method to transform the values passed it into it as a parameter ?

You just list the values:

C#

    List<string> l1 = new List<string> { "heelo", "goodbye" };
    List<string> l2 = new List<string> { "heelo", "goodbye" };
    List<int> l3 = new List<int> { 1, 2, 3, 4 };
    var x = AllCombinationsOf(l1, l2);
    ...

public static List<List<T>> AllCombinationsOf<T>(params List<T>[] sets)
    {
    Console.WriteLine(sets.Length);
    return sets.ToList();
    }

Obviously, you can't add the third list into the parameters, but if you just list your params, they will be passed as an array of List-of-strings
