How to Convert Base64 String to Image in C#?

To convert a Base64 string into an image in C#, we will follow these steps:

• Decode the Base64 string into a byte array.
• Create a memory stream from the byte array.
• Use the Image.FromStream method to create an image from the memory stream.

C# Program:

using System;
using System.Drawing;
using System.IO;

class Program
{
    static void Main()
    {
        string base64String = "<YOUR_BASE64_STRING_HERE>";

        try
        {
            // Convert Base64 string to byte array
            byte[] imageBytes = Convert.FromBase64String(base64String);

            // Create memory stream from byte array
            using (MemoryStream ms = new MemoryStream(imageBytes))
            {
                // Create image from memory stream
                using (Image image = Image.FromStream(ms))
                {
                    // Save the image
                    image.Save("converted_image.jpg");
                }
            }

            Console.WriteLine("Image saved successfully.");
        }
        catch (Exception ex)
        {
            Console.WriteLine("An error occurred: " + ex.Message);
        }
        Console.ReadKey();
    }
}

Replace "YOUR_BASE64_STRING_HERE" with your actual Base64 string. When you run this program, it will decode the Base64 string, create an image from it, and save the image as "converted_image.jpg" in the bin/debug folder in the program.
