+
+The **`.PadRight()`** method in C# is used to add padding characters to the right of a string to achieve a specified total length. By default, it uses spaces as the padding character, but a custom character can also be specified.
+
+## Syntax
+
+```pseudo
+string.PadRight(int totalWidth, char paddingChar)
+```
+
+- `totalWidth`: The desired total length of the string, including padding. If the specified width is less than the string's length, no padding is added.
+- `paddingChar`(Optional): The character to use for padding. Defaults to a space character (`' '`).
+
+> **Note**: The `.PadRight()` method does not modify the original string. It generates and returns a new string with padding applied to achieve the specified total width.
+
+## Example
+
+### Default Padding with Spaces
+
+```cs
+using System;
+class Program
+{
+    static void Main()
+    {
+        string name = "John";
+        string paddedName = name.PadRight(10);
+        Console.WriteLine($"'{paddedName}'");
+    }
+}
+```
+
+The above code generates the output as follows:
+
+```shell
+'John      '
+```
+
+### Custom Padding Character
+
+```cs
+using System;
+
+class NameFormatter
+{
+    public static void Main(string[] args)
+    {
+        string name = "John";
+        string paddedName = name.PadRight(10, '-');
+        Console.WriteLine($"'{paddedName}'");
+    }
+}
+```
+
+The output of the above code will be:
+
+```shell
+'John------'
+```
+
+### Handling Shorter Total Width
+
+If the specified `totalWidth` is less than the length of the string, the original string is returned:
+
+```cs
+using System;
+
+class NamePaddingExample
+{
+    public static void Main(string[] args)
+    {
+        string name = "John";
+        string result = name.PadRight(3);
+        Console.WriteLine($"'{result}'");
+    }
+}
+```
+
+Here's what the output of this code will be:
+
+```shell
+'John'
+```
+
+## Codebyte Example
+
+Run the following example to understand how the `.PadRight()` method works:
+
+```codebyte/csharp
+using System;
+
+class Program
+{
+    static void Main()
+    {
+        string word = "Align";
+        // Pad with spaces to a total width of 15
+        Console.WriteLine("'" + word.PadRight(15) + "'");
+
+        // Pad with asterisks to a total width of 15
+        Console.WriteLine("'" + word.PadRight(15, '*') + "'");
+    }
+}
+```
