You can make have the list contain any object you like. Why don't you create a custom object

Custom Object

public class CustomObject
{
    public string StringValue { get; set; }
    public int IntValue { get; set; }

    public CustomObject()
    {
    }

    public CustomObject(string stringValue, int intValue)
    {
        StringValue = stringValue;
        IntValue = intValue;
    }
}

List Creation

List<CustomObject> CustomObject = new List<CustomObject>();

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>

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