How to get first character of a string in C#

In this tutorial, we are going to learn about how to get the first character of a string in C#.

Consider, we have the following string.

string str = "youtube";

Now, we want to get the first character y from the above string.

Getting the first character

To access the first character of a string, we can use the subscript syntax [] by passing the first character index 0.

Note: In C# strings are the sequence of characters that can be accessed by using its character index.

Here is an example, that gets the first character y from the following string:

using System;
class StringCharacter {
  static void Main() {
    string str = "youtube";
    char firstCharacter = str[0];
    Console.WriteLine(firstCharacter);
  }
}

Output:

"y"

Similarly, we can also get the first character of a string by using the Substring() method in C#

using System;
class StringCharacter {
  static void Main() {
    string str = "youtube";
    string firstCharacter = str.Substring(0,1);
    Console.WriteLine(firstCharacter);
  }
}

Note: The extraction starts at index 0 and ends before index 1.
