NetworkStream截断我的数据？(NetworkStream truncates my data?)

 在同一台电脑上，我有2个控制台应用程序。 （客户端发送文件到服务器） 
 
 在我开始之前，我只想提一下，我正在使用这2个async函数： 
 
 从NetworkStream读取： 
 
 public static Task<int> ReadAsync1(this NetworkStream networkStream, byte[] buffer, int offset, int size)
   {
     return Task<int>.Factory.FromAsync(networkStream.BeginRead, networkStream.EndRead, buffer, offset, buffer.Length, networkStream);
   }
 
 为了写入NetworkStream ： 
 
   public static Task WriteAsync1(this NetworkStream networkStream, byte[] buffer, int offset, int size)
    {
      return Task.Factory.FromAsync(networkStream.BeginWrite, networkStream.EndWrite, buffer, offset, buffer.Length, networkStream);
    }
 
 我的客户代码 ： 
 
 （让我们拿一个简单的文件，我知道它的大小） 
 
 
 我的代码发送： 
 
 NetworkStream ns = socketForServer.GetStream();
 ns.WriteAsync1(File.ReadAllBytes(@"c:\r\1.jpg"), 0, 1593899);
 ns.Flush();
 
 我的服务器代码 :(阅读...） 
 
byte[] d = new byte[1593899];
networkStream.Read(d, 0, d.Length);
File.WriteAllBytes(@"c:\r\2.jpg",d);
 
 结果： 
 
 2.jpg写的是： 
 
 
 那么问题在哪里？ 
 
 2.jpg已损坏！ 当我尝试打开图像时，我看到： 
 
 
 （而不是像1.jpg一样的图像） 
 
 所以我去看看“十六进制”出了什么问题： 
 
 我发现一段时间后 - 它写成零： 
 
 更大的图像 
 
 
 题 
 
 我究竟做错了什么 ？ 我该如何修复代码才能发送整个文件？ 

On the same computer I have 2 console applications. (client sends a file to server)
 
Before I start I just want to mention that i'm using those 2 async functions : 
 
For reading from NetworkStream:
 
 public static Task<int> ReadAsync1(this NetworkStream networkStream, byte[] buffer, int offset, int size)
   {
     return Task<int>.Factory.FromAsync(networkStream.BeginRead, networkStream.EndRead, buffer, offset, buffer.Length, networkStream);
   }
 
For writing to NetworkStream:
 
   public static Task WriteAsync1(this NetworkStream networkStream, byte[] buffer, int offset, int size)
    {
      return Task.Factory.FromAsync(networkStream.BeginWrite, networkStream.EndWrite, buffer, offset, buffer.Length, networkStream);
    }
 
My client code : 
 
(let's take a simple file which I know it's size)
 
 
My code for sending:
 
 NetworkStream ns = socketForServer.GetStream();
 ns.WriteAsync1(File.ReadAllBytes(@"c:\r\1.jpg"), 0, 1593899);
 ns.Flush();
 
My Server code : (reading...)
 
byte[] d = new byte[1593899];
networkStream.Read(d, 0, d.Length);
File.WriteAllBytes(@"c:\r\2.jpg",d);
 
Result : 
 
2.jpg is written : 
 
 
So where is the problem ? 
 
2.jpg is corrupted ! When I try to open the image I see this : 
 
 
(instead of a the same image as 1.jpg)
 
So I went to see the "HEX" for what is wrong : 
 
I found out that after a while -all it writes are zeros :
 
larger iamge
 
 
Question
 
What am I doing wrong ? And how can I fix the code so it will send the whole file ?
