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

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

var Value1 = "ddabcgghh";

if (Value1.Contains("abc"))
{
    found = true;
}

It could be within the first 3, 4 or 5 characters.

Or if you need to set the value of found:

found = Value1.StartsWith("abc")

Edit: Given your edit, I would do something like:

found = Value1.Substring(0, 5).Contains("abc")
