Question

I have this code. I am trying to retrieve just the text “first program”. Considering that i know the index say 25 and total length of string is 35.

string text="Hello world ! This is my first program";

Response.Write(text.SubString(25,35));

But i get the error during runtime “System.ArgumentOutOfRangeException: startIndex cannot be larger than length of string”

Answer 1

The parameters for String.Substring are:

public string Substring(int startIndex, int length)

You’re trying to take 35 characters after the 26th character (startIndex is zero-based), which is out of range.

If you just want to get from the 25th character to the end of the string use text.SubString(24)
