Memory stream

[sirisha guttikonda]

Hi all .. I'm trying to save an image from memory stream content. but getting error like "Parameter is not valid." at newImage = System.Drawing.Image.FromStream(ms); can you please suggest me. Here is my code..

System.Drawing.Image newImage;

using (MemoryStream ms = new MemoryStream(photoByte, 0, photoByte.Length))
{

                    ms.Write(photoByte, 0, photoByte.Length);
                    
                    newImage = System.Drawing.Image.FromStream(ms);

                   
                    newImage.Save(strFileName);

                    img.Attributes.Add("src", strFileName);
                }

Thanks

After writing to the stream you have to reset the position to the beginning of the stream before reading it.

Despite everything, the person most likely to be fooling you next is yourself.

When you call new MemoryStream(photoByte, 0, photoByte.Length), the contents in the photoByte will be written to the stream. So calling the Write() again is pointless. Here is a code which worked at my end

using(MemoryStream stream = new MemoryStream(photoByte,0,photoByte.Length))
using (Image image = Image.FromStream(stream))
{
image.Save(@"filename.jpg", System.Drawing.Imaging.ImageFormat.Jpeg);
}

All C# applications should call Application.Quit(); in the beginning to avoid any .NET problems.- Unclyclopedia How to use google | Ask smart questions
