convert base64 string into image

Question

I m trying to convert base64 string into image using below code

 byte[] imageBytes = Convert.FromBase64String(base64String);
 MemoryStream ms = new MemoryStream(imageBytes, 0, imageBytes.Length);

 // Convert byte[] to Image
 ms.Write(imageBytes, 0, imageBytes.Length);
 Image image = Image.FromStream(ms, true);

but it is always giving me an error "parameter is not valid."

And also I want to store image in folder after conversion.

Answer 1

You do not Need

ms.Write(imageBytes, 0, imageBytes.Length);

and for your stream you can use:

MemoryStream ms = new MemoryStream(imageBytes)

thats all i think.

Remember to use using blocks for your MemoryStream

Image image;
using (var ms= new MemoryStream(Convert.FromBase64String(base64String)))
{
  image = Image.FromStream(ms, true);
}

To store your Image in FileSytem just use:

image.Save("c:\\myimage.bmp");
