Question

In my winform application, I have an arraylist containing a dynamic number of string arrays. I need to somehow remove each string array from the array list and then use these string arrays as parameters for a function. The number of string arrays in the arraylist can vary as they are created dynamically.

The method declaration:

public void mychartbuilder(string[] Column1, string[] Column2 = null, string[] Column3 = null, string[] Column4 = null)

The following is causing the biggest headache. Since there is a dynamic number of arrays in the list, I can’t determine how to pull them out and then send them into the function as parameters.

foreach (string[] myarray in myArrayList)
    {
        string[] copy1 = new string[rcounter];
    }
mymethods.mychartbuilder(//string array parameters will go here)

Thanks in advance.

Answer 1

while(arrayList.Count < 4)
{
  arrayList.Add(null);
}

mychartbuilder((string[])arrayList[0], (string[])arrayList[1], (string[])arrayList[2], (string[])arrayList[3]);

Note that you can use List<string[]> rather than an ArrayList to avoid all of the casting.
