我正在使用这样的函数在 C 代码中创建 C 管道：

extern int *create_pipe() {
  int *_pipe = (int *)malloc(2 * sizeof(int));
  pipe(_pipe);

  return _pipe;
}

我在 C# 中绑定了这个函数，如下所示：

[DllImport("mydll")]
private static unsafe extern int *create_pipe();

我这样调用 C# 代码：

unsafe {
  int *pipe = create_pipe();

  hostout = pipe[1];
  hostin = pipe[0];
}

然后我尝试BinaryWriter像这样创建一个管道：

var writer = new BinaryWriter(new AnonymousPipeClientStream(PipeDirection.Out, new SafePipeHandle(new IntPtr(hostout), false)));

我尝试给它写一个简单的整数值：

writer.Write(50);

但我得到这个错误：

Unhandled Exception:

任何想法如何完成我正在尝试做的事情？

先感谢您！
