How to get the first n characters of a string in C#

In this tutorial, we are going to learn about how to get the first n number of characters from a string in C#

Getting the first n characters

To get the first n characters of a string, we can use the built-in Substring() method by passing the 0, n as arguments to it.

Where 0 is the start index, n is the number of characters we need to get from the string.

Here is an example, that gets the first 3 characters from a name string:

 string name = "pearson";
 string firstThree =  name.Substring(0,3);

 Console.WriteLine(firstThree);

Output:

pea

In the example above, we have passed 0, 3 as arguments to the Substring() method. So it starts the extraction at index position 0 and extracts before the index 3.
