Convert.ToBase64String() Method in C#


The Convert.ToBase64String() method in C# is used to convert the value of an array of 8-bit unsigned integers to its equivalent string representation that is encoded with base-64 digits.

Syntax

Following is the syntax −

public static string ToBase64String (byte[] arr);

Above, arr is an array of 8-bit unsigned integers.

Example

Let us now see an example to implement the Convert.ToBase64String() method −

Using System;
public class Demo {
   public static void Main(){
      byte[] val1 = {5,10,15,20,25,30};
      string str = Convert.ToBase64String(val1);
      Console.WriteLine("Base 64 string: '{0}'", str);
      byte[] val2 = Convert.FromBase64String(str);
      Console.WriteLine("Converted byte value: {0}", BitConverter.ToString(val2));
   }
}

Output

This will produce the following output −

Base 64 string: 'BQoPFBke'
Converted byte value: 05-0A-0F-14-19-1E
