Convert List to List in C#

Question

I want to convert a List to a List.

Here is my code:

void Convert(List stringList)
{

If you don't want to use Linq (which I always find hard to understand), your code looks right, but of course you need to return something:

List Convert(List stringList)
{
    List intList = new List();  

    for (int i = 0; i < stringList.Count; i++) 
    {  
        intList.Add(int.Parse(stringList[i]));  
    }
    return intList;
}

Be aware that this will throw an exception if the string list contains something that is not parseable as an int.

Edit: Better yet, use a foreach loop:

List Convert(List stringList)
{
    List intList = new List();  

    foreach(String s in stringList) 
    {  
        intList.Add(int.Parse(s));  
    }
    return intList;
}
