Question

我正在尝试构建客户端应用程序：

ShellStream mainStream = client.CreateShellStream("xterm", 80, 24, 800, 600, 1024); //the library's class which represents the main stream of data between client and server
StreamReader reader = new StreamReader(mainStream);
StreamWriter writer = new StreamWriter(mainStream); //wrappers for the main stream

向服务器发送请求：

await writer.WriteAsync(command);
await writer.FlushAsync();

......并阅读回复：

async Task<string> GetResponse(CancellationToken cts)
StringBuilder sb = new StringBuilder();
char[] buffer = new char[128];
int i = 0;
while (!cts.IsCancellationRequested)//when timeout is tick then cancel operation
     {
     while ((i = await reader.ReadAsync(buffer, 0, buffer.Length)) != 0)
            {
            sb.Append(buffer, 0, i);
            }
return sb.ToString();

问题是我无法从服务器读取响应，但StreamReader有一个内部char数组，charBuffer，它有响应。此外，GetResponse返回由StreamWriter编写的命令。这有什么不对？

编辑：当我更换`writer.WriteAsync（command）;```writer.WriteLineAsync（command）;`它开始工作了。但是当我发送特定命令（`geth --verbosity 0`）时，它不再发送。这种行为对我来说很奇怪。

无法从StreamReader读取数据
