Image.FromStream报错参数无效

Question

 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);//出错行
有时候行，有时候就不行

Answer 1

为接受完全！ 你就转化 ，当然错！
看看 发送时候大小，和 你转化时候的大小》？需要判断是否接受完！Socket 是 分包发送的！

Answer 3

发
MemoryStream ms = new MemoryStream(...);
byte[] x=ms.ToArray();
Convert.ToBase64String(x);  收
Convert.FromBase64CharArray(...)

Answer 4

ms不能释放，不能为null，不能Flash()

Answer 5

我也遇到了使用Image.Fromstream()时程序报参数无效。悲催
