实施“命名管道”[重复]

Question

我想实现一个“命名管道”，用于在 C# 和 Python 进程之间交换双数组 有人知道吗？

我找到了一些代码，但我无法理解

Answer 1

[DllImport("kernel32.dll")]
static extern unsafe int CreateNamedPipe(
    string lpName, uint dwOpenMode, uint dwPipeMode,
    uint nMaxInstances, int nOutBufferSize,
    int nInBufferSize, int nDefaultTimeOut,
    ref SECURITY_ATTRIBUTES lpSecurityAttributes
    );

[DllImport("kernel32.dll")]
static extern unsafe int ConnectNamedPipe(
    int hNamedPipe,
    ref OVERLAPPED lpOverlapped
    );

[DllImport("kernel32.dll")]
static extern unsafe int DisconnectNamedPipe(
    int hNamedPipe
    );

[DllImport("kernel32.dll")]
static extern unsafe int WriteFile(
    int hFile, void* lpBuffer,
    int nNumberOfBytesToWrite,
    int* lpNumberOfBytesWritten,
    ref OVERLAPPED lpOverlapped
    );

[DllImport("kernel32.dll")]
static extern unsafe int ReadFile(
    int hFile, void* lpBuffer,
    int nNumberOfBytesToRead,
    int* lpNumberOfBytesRead,
    ref OVERLAPPED lpOverlapped
    );

[DllImport("kernel32.dll")]
static extern unsafe int CloseHandle(
    int hObject
    );

A：

此方法用于使用 Windows 命名管道与单独的进程通信。如果你想在同一进程中的两个线程之间（或同一台机器上的两个进程之间）进行通信，你可以使用MemoryMappedFile或P/InvokeCreateFileMapping和MapViewOfFile。
