How to get INDEX of word inside a string

Question

I am trying to get the INDEX of a word inside a string and if possible also to delete all the characters previous to this word in the string, it would make my life easier.

Answer 1

You'll want to use the IndexOf function on a string. This will tell you the starting character position of the word, character, etc that you're looking for.

Here is an example console app:

    static void Main(string[] args)
    {
        String testing = "text that i am looking for";
        Console.Write(testing.IndexOf("looking") + Environment.NewLine);
        Console.WriteLine(testing.Substring(testing.IndexOf("looking")));

        Console.ReadKey();

    }

This will output:
15
looking for

Yes, you can use Substring to delete all the characters previous

string str = "I'm stuck here please help, something else....yyyy";
string output = str.Substring(str.IndexOf("help"));
WriteLine($"Output string value  :{output}");//help,something else....yyyy
