Question

I’m sorry about the naive question. I have the following:

public Array Values
{
  get;
  set;
}

public List<object> CategoriesToList()
{
  List<object> vals = new List<object>();
  vals.AddRange(this.Values);

    return vals;
}

But this won’t work because I can’t type the array. Is there any way to easily fix the code above or, in general, convert System.Collections.Array to System.Collections.Generic.List?

Answer 1

Make sure you’re using System.Linq; and then change your line to:

vals.AddRange(this.Values.Cast<object>());

Edit: You could also iterate over the array and add each item individually.

Edit Again: Yet another option to simply cast your array as object[] and either use the ToList() function or pass it into the List<object> constructor:

((object[])this.Values).ToList();

or

new List<object>((object[])this.Values)
