Best way to split a string

Question

Hello,
what's the best way to split a string to obtain the second substring(divided using ':')?
I know how to do it using byte num=0; string[] array = tosplitstring.Split(':'); foreach(string substring in array) {num++; if(num==2){string secondelement=substring;} ``}
I am quite sure this method is not the best. Thanks in advance

It's wise to use assertion e.g.

string tosplitstring = "first:second:third";
var split = tosplitstring.Split(':');

if (split.Length >1)
{
    var indexToFind = 2;
    var items = split.Select((value, index) => new {Value = value, Index = index}).ToList();
    var result = items.FirstOrDefault(x => x.Index == indexToFind);
    Debug.WriteLine(result is not null ? result.Value : $"Failed to find {indexToFind}");
}
