我正在寻找示例代码,该示例代码如何从用C编写的dll中导入函数,该函数等效于 C#.NET 的DllImport 。 这是可能的? 我正在使用Windows。\感谢您的帮助。 提前致谢。

    You want to use cgo. Here's an introduction.

    Use the same method that the Windows port of Go does. See the source code for the Windows implementation of the Go syscall package. Also, take a look at the source code for the experimental Go exp/wingui package

    There are a few ways to do it.

    The cgo way allows you to call the function this way:

    import ("C")

    It will call libraries basically by "linking" against the library. You can put C code into Go and import the regular C way.

    There are more methods such as syscall

    import (
    // ..
    kernel32, _        = syscall.LoadLibrary("kernel32.dll")
    getModuleHandle, _ = syscall.GetProcAddress(kernel32, "GetModuleHandleW")


    func GetModuleHandle() (handle uintptr) {
        var nargs uintptr = 0
        if ret, _, callErr := syscall.Syscall(uintptr(getModuleHandle), nargs, 0, 0, 0); callErr != 0 {
        abort("Call GetModuleHandle", callErr)
        } else {
            handle = ret

    There is this useful github page which describes the process of using a DLL: https://github.com/golang/go/wiki/WindowsDLLs

    There are three basic ways to do it.
