C# IntPtr.Size始终为4，尽管64位操作系统中有任何CPU

我正在构建一个Outlook加载项，该加载项在64位Outlook操作系统上运行。 但是，我无法获得正确的指针大小，以便触发RedemptionLoader代码来加载64位dll。。。它总是给我指针大小是4

我已经阅读了下面的内容，也采纳了他们的建议，但是没有去

因此，在我的项目Visual Studio 2015中的C#项目中，我将其设置为

任何CPU

，然后在我的64位WiX设置项目中，我确保它具有

x64

作为

$（平台）

。这样,

<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Debug|x64' ">

---

如果是4，则可以确保进程是32位的。编译为“任意CPU”将匹配主机应用程序（Outlook）的位，而不是主机操作系统

---

Outlook是否真的说它是64位的？

您确定主进程是64位的吗？是的。。。上面写着64位，我真的不知道为什么它会打印4。我构建外接程序的计算机安装了32位Outlook，但我认为这在目标计算机上并不重要？调试时是否使用VSTO宿主进程？我确实在属性Debug>Enable Debuggers>“Enable The Visual Studio宿主进程”中看到了该选项，并且选中了该框。那就是你说的那个吗？我已经取消选中该框并重建了解决方案，仍然是一样的…如果明确针对x64，会发生什么？我已经完全创建了一个全新的安装程序项目，重建并重新打包了整个项目，安装了它，一切运行正常，您的赎回甚至加载了正确的64位dll，只有在卸载过程中，它才会尝试加载32位（由于指针大小为4）这完全是mind=Blow。。。
