How to Create a Bitmap from a Byte Array in C#?

Creating a Bitmap from Byte Array in C#

Creating a Bitmap image from a byte array is a common task in image processing applications. In C#, you can achieve this using the Bitmap class and the MemoryStream class.

Converting Byte Array to Bitmap

To convert a byte array to a Bitmap, follow these steps:

1. Create a new MemoryStream object using the byte array as input:

using (var ms = new MemoryStream(imageData))
{
    // Create a Bitmap object using the MemoryStream
    Bitmap bmp = new Bitmap(ms);
}

2. The Bitmap(MemoryStream) constructor overload reads the image data from the MemoryStream and creates a Bitmap object.

Additional Notes

• Ensure that the byte array indeed contains valid image data, otherwise an ArgumentException will be thrown.
• The Bitmap(MemoryStream) constructor has limitations on image dimensions; dimensions greater than 65,535 pixels in any direction will cause an ArgumentException.
