How to Convert Base64 String to Image in C#?

To convert a Base64 string into an image in C#, we'll 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.

Let's see this in action with a simple C# program:

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

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

        // 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
            Image image = Image.FromStream(ms);

            // Output the image
            image.Save("output_image.jpg");
        }

        Console.WriteLine("Image saved successfully.");
    }
}

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 "output_image.jpg" in the same directory as your program.
