Decoding a base64 image

Question

I would like to decode a base64 string to an image. I'm using the following code to decode,

string base64string = subSocket.ReceiveFrameString();
       
if (base64string.Length > 1000)
{
    var base64Data = Regex.Match(base64string, @"data:image/(?<type>.+?),(?<data>.+)").Groups["data"].Value;
    byte[] imgBytes  = Convert.FromBase64String(base64Data);
    myTexture.LoadRawTextureData(imgBytes);
    myTexture.Apply();

    rawImg.texture = myTexture;
}

Unfortunately, it throws FormatException. How do I properly decode the base64 image. Following is my base64 string.

Answer 1

As there can not be , in base64 string and also it is the separator, so the image part is right after the comma:

byte[] imgBytes  = Convert.FromBase64String(base64string.Split(',')[1]);
