C# / .NET - remove first character from string

In this article, we would like to show you how to remove the first character from the string in C# / .NET.

1. Using String substring() method

In the example below, we use the String Substring(int beginIndex) method, where we assign 1 to beginIndex, so we get a string without the first character.

using System;

public class StringUtils
{
    public static void Main(string[] args)
    {
        String text = "ABCD";
        String substring = text.Substring(1);

        Console.WriteLine(substring); // BCD
    }
}

Output:

BCD

2. Using range operator ..

The range operator .. is used to make a slice of the collection.

using System;

public class StringUtils
{
    public static void Main(string[] args)
    {
        String text = "ABCD";
        String substring = text[1..];

        Console.WriteLine(substring); // BCD
    }
}

Output:

BCD
