# Get the first digit of a number in C#

In this tutorial, we are going to learn about how to get the first digit of a number in C# with the help of examples.

In C#, strings are the sequence of characters, where the index of the first character is `0`, the second character is `1`, third character is `3` and the last character index `-1`.

Consider, we have a following number:

``int pincode = 67683``

To get the first digit of a number in C#:

1. Convert the number to a string using the `ToString()` method.

2. Use the square brackets syntax `[]` to access the first character of a string.

3. Now, Convert the character to a string

4. At final, convert the result back to a number to get the first digit of the number.

Here is an example:

``````using System;

class GetFirstDigit {
static void Main() {
int pinCode = 67683;
int firstDigit = int.Parse(pinCode.ToString()[0].ToString());
Console.WriteLine(firstDigit);
}
}``````

Output:

``6``

In the example above, first we converted the number to a string, so we can use the square brackets syntax on it.

Now, you can access the characters of a string, by using the square brackets syntax and specifying an index.

At last we have used the `int.Parse()` method to convert the string to a number.
