将uint16数组转换为字符串

Question

I have an array of uint16 coming from WinAPI PROCESSENTRY32.szExeFile that I wanna convert to a string.

Here's my var type

var hello [260]uint16

now I need to convert hello to a string. How can I do that?

Edit

Here's what I've tried:

func szExeFileToString(ByteString [260]uint16) string {
    b := make([]byte, len(ByteString))

    for i, v := range ByteString {
        b[i] = byte(v)
    }

    return string(b)
}

However, this returns pretty weird strings... result (the function should convert Windows process names in the PROCESSENTRY32.szExeFile (-> [260]uint16) type to string)

package windows

import "golang.org/x/sys/windows"

func UTF16ToString

func UTF16ToString(s []uint16) string

UTF16ToString returns the UTF-8 encoding of the UTF-16 sequence s, with a terminating NUL removed.

Use windows.UTF16ToString. For example,

package main

import (
    "fmt"
    "golang.org/x/sys/windows"
)

func main() {
    var szExeFile [260]uint16
    szExeFile = [260]uint16{'e', 'x', 'e', 'F', 'i', 'l', 'e'}

    exeFile := windows.UTF16ToString(szExeFile[:])
    fmt.Println(exeFile)
}

Output:

exeFile
