Create list in C# with string and int datatypes

Question

How can I create a list which holds both string value and int value? Can anyone help me please.Is it possible to create a list with different datatypes?

Answer 1

You could use:

var myList = new List<KeyValuePair<int, string>>();
myList.Add(new KeyValuePair<int, string>(1, "One");

foreach (var item in myList)
{
    int i = item.Key;
    string s = item.Value;
}

or if you are .NET Framework 4 you could use:

var myList = new List<Tuple<int, string>>();
myList.Add(Tuple.Create(1, "One"));

foreach (var item in myList)
{
    int i = item.Item1;
    string s = item.Item2;
}

If either the string or integer is going to be unique to the set, you could use:

Dictionary<int, string> or Dictionary<string, int>

Answer 2

List<T> is homogeneous. The only real way to do that is to use List<object> which will store any value.
