C# / .NET - remove first 3 characters from string
0 points
In this article, we would like to show you how to remove the first 3 characters from the string in C# / .NET.
Quick solution:
xxxxxxxxxx1
string text = "ABCDE";2
3
string result = text.Substring(3);4
Console.WriteLine(result); // DE
In this example, we use String Substring() method to create a new result substring from the text string without the first 3 characters.
Syntax:
xxxxxxxxxx1
Substring(int startIndex, int length);Note:
If
lengthis not given, substring will be done fromstartIndexto the end of the text.
Practical example:
xxxxxxxxxx1
using System;2
3
public class StringUtils4
{5
public static void Main(string[] args)6
{7
string text = "ABCDE";8
9
string result = text.Substring(3);10
Console.WriteLine(result); // DE11
}12
}Output:
xxxxxxxxxx1
DEIn this example, we create sb StringBuilder object from the text string, then we use Remove() method on the sb to delete the first 3 characters.
Syntax:
xxxxxxxxxx1
Remove(int startIndex, int length)Practical example:
xxxxxxxxxx1
using System;2
using System.Text;3
4
public class StringUtils5
{6
public static void Main(string[] args)7
{8
string text = "ABCDE";9
10
// Create StringBuilder object11
StringBuilder sb = new(text);12
13
// Remove first 3 characters14
sb.Remove(0, 3);15
16
Console.WriteLine(sb);17
}18
}Output:
