How to determine if string contains specific substring within the first X characters

Question

I want to check whether Value1 below contains \"abc\" within the first X characters. How would you check this with an if statement?

Answer 1

You can also use regular expressions (less readable though)

string regex = "^.{0,7}abc";

System.Text.RegularExpressions.Regex reg = new System.Text.RegularExpressions.Regex(regex);
string Value1 = "sssddabcgghh";

Console.WriteLine(reg.Match(Value1).Success);
