String Manipulation.Find string between 2 indexes

Question

Given a string eg 500 chars and I want to pick a string between index 400 and index 430. How do you write such a function?

Thanks

Answer 1

Use the string.Substring() method.

Like var truncString = longString.Substring(400, 30);.

Note, that you should check the length of longString that it is at least 430 chars. If it is not, Substring will throw an exception.

Answer 2

string x = "aaaa";
string part = x.Substring(400,Math.Min(x.Length,430)-400);
