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

I am guessing you want to parse that string into different parts.

public static void Main() {
    var input = @"error: file.ext: line 10: invalid command [test (: ]";
    var splitted = input .Split(separator: new[] {": "}, count: 4, options: StringSplitOptions.None);

    var severity = splitted[0]; // "error"
    var filename = splitted[1]; // "file.ext"
    var line = splitted[2];     // "line 10"
    var message = splitted[3];  // "invalid command [test (: ]"
}
