There are occassions where you might have to convert or encode a string to base64 and vice versa in C#.
How to encode and decode base64 string in C# ?
This can be achieved easily in C# using the Convert static class which provides the static methods ToBase64String and FromBase64String.
An example of how to implement this is shown below.
public static string EncodeBase64String(string input)
{
var plainText = System.Text.Encoding.UTF8.GetBytes(input);
return Convert.ToBase64String(plainText);
}
public static string DecodeBase64String(string input)
{
var base64EncodedBytes = Convert.FromBase64String(input);
return System.Text.Encoding.UTF8.GetString(base64EncodedBytes);
}Output
The complete code snippet that is used in this example is show below.
using System;
using System.Linq;
using System.Collections.Generic;
namespace ConsoleApp1
{
class Program
{
static void Main(string[] args)
{
string input = "Senthil";
string encodedString = EncodeBase64String(input);
Console.WriteLine(encodedString);
string decodedString = DecodeBase64String(encodedString);
Console.WriteLine(decodedString);
Console.ReadLine();
}
public static string EncodeBase64String(string input)
{
var plainText = System.Text.Encoding.UTF8.GetBytes(input);
return Convert.ToBase64String(plainText);
}
public static string DecodeBase64String(string input)
{
var base64EncodedBytes = Convert.FromBase64String(input);
return System.Text.Encoding.UTF8.GetString(base64EncodedBytes);
}
}
}
