Getting the Letters from One Index to Another in a String Using C#

In C#, you can use the Substring method to get the letters from one index to another in a string. The Substring method takes two parameters: the starting index and the length of the substring.

Example

The following code shows how to use the Substring method to get the letters from index 3 to index 7 in the string "Hello World":

    string str = "Hello World";
    string substring = str.Substring(3, 5);

    Console.WriteLine(substring);
  

This code will print the following output:

    World
  

Additional Notes

• The starting index is zero-based.
• If the starting index is greater than or equal to the length of the string, an ArgumentOutOfRangeException is thrown.
• If the length of the substring is greater than the number of characters remaining in the string, the substring will be truncated.
