BinaryWrite an image

Bammer22 · March 2nd, 2004, 01:28 PM

I am trying to BinaryWrite an image from a binary string that I am storing in the web.config file. The image is just a 1x1 pixel gif. I am setting the content type to "image/gif", but the output is just my string. Any suggestions? Code is below:

byte[] bytes = Encoding.UTF8.GetBytes(ConfigurationSettings.AppSe ttings["PixelBinaryData"].ToString());
httpContext.Response.ContentType = "image/gif";
httpContext.Response.BinaryWrite(bytes);

You might want to look into embedded resources for this. I have had good luck with using those for this very purpose. There is a utility you can download that will create a resource file for the image you tell it to convert, then you can just copy the one XML node for that image into an existing resource file. The image resource will get compiled right into the assemble/executable.

its a sample to save image file in a Database,I hope u need this.

Code:

                if( FileOpenDlg.ShowDialog() == DialogResult.OK)
                {
                    string file = FileOpenDlg.FileName;
                    System.IO.FileStream stream = new System.IO.FileStream(file, System.IO.FileMode.Open, System.IO.FileAccess.Read);
                    byte[] buffer = new byte[stream.Length];
                    stream.Read(buffer, 0, (int)stream.Length);
                    stream.Close();
                    string strName = System.IO.Path.GetFileNameWithoutExtension(file);

                    //SavePic
                    DataRow PicRow;
                    PicRow = dsDabir1.Tables["Images"].NewRow();
                    PicRow.SetParentRow(IncomeRow);
                    PicRow["IsScaned"] = 0;
                    PicRow["ImgPic"] = buffer;
                    dsDabir1.Tables["Images"].Rows.Add(PicRow);
                    buffer = null;
                }//if
