如何把一张图片专程System.io.Stream?
------解决方案--------------------------------------------------------
FileStream fileStream = new FileStream("图片路径", FileMode.Open);
Stream stream = fileStream as Stream;
------解决方案--------------------------------------------------------
Stream stream = null;
System.Drawing.Image.FromFile("图片路径").Save(stream, ImageFormat.Jpeg);
------解决方案--------------------------------------------------------
可将图片转成二进制，然后存储到数据库中
------解决方案--------------------------------------------------------
给你方法：
System.IO.FileStream fs = new System.IO.FileStream(Server.MapPath("Images图片.jpg", System.IO.FileMode.Open);
byte[] buffer = new byte[fs.Length];
fs.Read(buffer, 0, buffer.Length);
fs.Close();
------解决方案--------------------------------------------------------
不好意思少了个括号：
System.IO.FileStream fs = new System.IO.FileStream(Server.MapPath("Images图片.jpg"), System.IO.FileMode.Open);
byte[] buffer = new byte[fs.Length];
fs.Read(buffer, 0, buffer.Length);
fs.Close();
