C# third index of a character in a string

Question

is there a command that can get the third index of a character in a string? For example:

error: file.ext: line 10: invalid command [test:)]

Answer 1

Simply split the string by the char. This gives you an array that you can then use to target what you want.

var stringToSplit = "one_two_three_four";
var splitString = stringToSplit.Split("_");          
if (splitString.length > 3){
    var newString = $"{splitResult[0]}_{splitResult[1]}_{splitResult[2]}";
}
