The method of converting pictures, binary and string in C # _c# tutorial

The examples in this article describe the methods of converting pictures, binary, and strings in C #. Share to everyone for your reference, specific as follows:

protected void Button1_Click (object sender, EventArgs e) {//Picture into binary byte[] Imagebyte = Getpicturedata (Server.MapPath (
  "./uploadfile/111.png"));
  Binary converts to string picstr = Convert.tobase64string (imagebyte);
  Output String Response.Write (PICSTR);
  String binary byte[] imagebytes = convert.frombase64string (PICSTR);
  Read into the MemoryStream object MemoryStream MemoryStream = new MemoryStream (imagebytes, 0, imagebytes.length);
  Memorystream.write (imagebytes, 0, imagebytes.length);
  Binary turn into picture save System.Drawing.Image image = System.Drawing.Image.FromStream (MemoryStream); Image.
Save (Server.MapPath ("./uploadfile/222.png")); ///<summary>///binary flow picture///</summary>///<param name= "streambyte" > Binary flow </param>///<retu rns> Pictures </returns> public System.Drawing.Image returnphoto (byte[] streambyte) {System.IO.MemoryStream ms = new S Ystem. Io.
  MemoryStream (Streambyte);
  System.Drawing.Image img = System.Drawing.Image.FromStream (ms);
return img; }///<summary&Gt Picture to binary///</summary>///<param name= "ImagePath" > Picture address </param>///<returns> binary </ Returns> public byte[] Getpicturedata (string imagepath) {//open using file stream according to the path of the picture file and save as byte[] FileStream fs = new FILESTR EAM (ImagePath, FileMode.Open);//Can be other overloaded methods byte[] Bydata = new Byte[fs.
  Length]; Fs.
  Read (bydata, 0, bydata.length); Fs.
  Close ();
return bydata; ///<summary>///pictures to binary///</summary>///<param name= "Imgphoto" > Image objects </param>///<returns > Binary </returns> public byte[] Photoimageinsert (System.Drawing.Image imgphoto) {//convert Image to stream data and save as byte[] Mem
  Orystream mstream = new MemoryStream ();
  Imgphoto.save (Mstream, SYSTEM.DRAWING.IMAGING.IMAGEFORMAT.BMP); byte[] Bydata = new Byte[mstream.
  Length]; Mstream.
  Position = 0; Mstream.
  Read (bydata, 0, bydata.length); Mstream.
  Close ();
return bydata;

 }

PS: Here is a small series to recommend this site a picture of the BASE64 format of the online conversion tool, very practical value:
