Note: String indexes start with 0: [0] is the first character. [1] is the second character, etc.

This example prints thesecond character (1) inmyString:

Example

string myString = "Hello";Console.WriteLine(myString[1]);  // Outputs "e"

You can also find the index position of a specific character in a string, by using theIndexOf() method:

Example

string myString = "Hello";Console.WriteLine(myString.IndexOf("e"));  // Outputs "1"

Another useful method isSubstring(), which extracts the characters from a string, starting from the specified character position/index, and returns a new string. This method is often used together withIndexOf() to get the specific character position:

Example

// Full namestring name = "John Doe";// Location of the letter Dint charPos = name.IndexOf("D");// Get last namestring lastName = name.Substring(charPos);// Print the resultConsole.WriteLine(lastName);
