比较2个wchar_t数组 [英] Comparing 2 wchar_t arrays

问题描述

我敢肯定这太简单了，但是我来自C#背景，字符串很简单，现在我要进入一个不受管理的世界，这让我很困惑.

I'm sure this is sooo simple but I've come from a c# background where strings are easy and now I am making a small trip into the unmanaged world I am very confused.

基本上，我正在使用EnumDisplayDevices列出可用的设备，我想针对特定的适配器，因此我需要将DeviceString和DeviceName与一些已知值进行比较，以查看我是否有合适的适配器来工作.

Essentially I am using EnumDisplayDevices to list the available devices, I want to target a particular adapter so I need to compare DeviceString and DeviceName against some know values to see whether or not I have the right adapter to work on.

但是我很困惑，我将已知值定义为……

But I am stumped, I defined the known value as such...

wchar_t devName[] = L"Intel(R) HD Graphics Family";

但是直接比较不起作用- if(devName == theDisplay.DeviceName)

but direct comparison doesn't work - if(devName == theDisplay.DeviceName)

strcmp 似乎不适用于宽字符，所以我不知道该怎么做，有人知道该怎么做吗?

strcmp doesnt seem to work with wide chars so I have no idea what to do, anyone know how to do this please?

谢谢

推荐答案

使用 std :: wstring ，它具有 operator == .
