C# picturebox显示不出来图像

[charles27823349]

byte[] inum = new byte[32];
revSocket.Receive(inum);
int aa = BitConverter.ToInt32(inum, 0);
byte[] ib = new byte[aa];
revSocket.Receive(ib);
MemoryStream ms = new MemoryStream(ib);
Image image = Image.FromStream(ms);
//image.Save(@"c:\aa\j.gif", ImageFormat.Gif);

pictureBox1.Image = image;
没有显示，form底下一片白，程序能正常运行，如果用save保存下来可以打开，换成别的格式也不行

据说C#中要 \\ 路径

刷新的问题?写在重绘里看看?

//Byte[] result;

System.IO.MemoryStream ms =new  MemoryStream(result, 0, result.Length)  
  Response.ClearContent();
  Response.ContentType = "image/Gif";
  Response.BinaryWrite(ms.ToArray());

//或者添加一个处理图片的Handler，内容如下：
<%@ WebHandler Language="C#" Class="Handler" %>

using System.Web;
using System.IO;


public class Handler : IHttpHandler {
   
  public void ProcessRequest (HttpContext context) {
  
  int CategoryID = int.Parse(context.Request.QueryString["CategoryID"]);
  //调用Categories.GetPicture取得图片stream
  Stream stream = CategoriesPicture.GetPicture(CategoryID);
   
  if (stream !=null) {
  //取得图片stream大小
  int buffersize = (int)stream.Length;
  //建立buffer
  System.Byte[] buffer = new System.Byte[buffersize ] ;
  //调用stream.Read，从stream读取到buffer，并返回count
  int count = stream.Read(buffer, 0, buffersize);
  //返回图片字段buffer
  if (count!=0)
  context.Response.OutputStream.Write(buffer, 0, count);
  }

  }
 
  public bool IsReusable {
  get {
  return false;
  }
  }

}

这样可以,接收端代码

int rcv;
                    byte[] msgsize = new byte[4];
                    rcv = socket.Receive(msgsize, 0, 4, SocketFlags.None);
                    int size = BitConverter.ToInt32(msgsize, 0);

                    byte[] file = new byte[10000000];
                    int longer = file.Length;
                    int start = 0;
                    int mid = 0;
                    int count = socket.Receive(file, start, longer, SocketFlags.None);
                    mid += count;
                    longer -= mid;
                    while (count != 0)
                    {
                        count = socket.Receive(file, mid, longer, SocketFlags.None);
                        mid += count;
                        longer -= mid;
                    }
                    MemoryStream ms = new MemoryStream(file, 0, size, true);
                    pictureBox1.Image = Image.FromStream(ms);
                    ms.Close();
                    socket.Close();
