Go语言调用动态库需要注意动态库的版本，比如调用32位的动态库必须使用32位的go，否则会报下面的错误(xxx.dll是动态库的名称)：
panic: Failed to load xxx.dll: %1 is not a valid Win32 application.
-
使用syscall的NewLazyDLL和NewProc(效果如下)
2.使用syscall的LoadLibrary和GetProcAddress(效果如下)
3详细代码如下(zip.dll是一个提供压缩解压缩功能的第三方动态库，kernel32.dll是Windows的系统库)：
packagemain
import ( "fmt" "syscall" ) func main() { CompressFile() fmt.Println("\n") GetWindowVersion() } func CompressFile() { Compress := syscall.NewLazyDLL("zip.dll") Comp := Compress.NewProc("CompressFile") ret, _, err := Comp.Call() if ret != 1 { fmt.Println("Compress result:压缩失败", err) return } fmt.Println("Compress result:压缩成功") } func GetWindowVersion() { kernel , err := syscall.LoadLibrary("kernel32.dll") if err != nil { abort("LoadLibrary", err) } defer syscall.FreeLibrary(kernel) proc, err := syscall.GetProcAddress(kernel, "GetVersion") if err != nil { abort("GetProcAddress", err) } ret, _, _ := syscall.Syscall(uintptr(proc), 0, 0, 0, 0) print_version(uint32(ret)) } func abort(funcname string, err error) { panic(funcname + " failed: " + err.Error()) } func print_version(v uint32) { major := byte(v) minor := uint8(v >> 8) build := uint16(v >> 16) print("windows version ", major, ".", minor, " (Build ", build, ")\n") }
