it’s work

public static string Between(this string src, string findfrom, string findto)
{
    int start = src.IndexOf(findfrom);
    int to = src.IndexOf(findto, start + findfrom.Length);
    if (start < 0 || to < 0) return "";
    string s = src.Substring(
                   start + findfrom.Length, 
                   to - start - findfrom.Length);
    return s;
}

and it can be called as

string respons = Between("Hello i want to go."," i "," to ");

it return want
