编译时目标平台/处理器 [英] Target platform/processor at compile time

问题描述

在C＃中是否有一个#define，可以让我在编译时知道是针对x86（Win32）还是x64（Win64）进行编译？

Is there a #define in C# that allows me to know, at compile time, if I'm compiling for x86 (Win32) or x64 (Win64)?

推荐答案

默认情况下，无法执行此操作。原因是C＃代码不是在CLR上运行时才针对特定平台设计的。

By default there is no way to do this. The reason is that C# code is not designed to target a particular platform as it runs on the CLR.

虽然可以手动滚动。您可以在Visual Studio中使用项目配置设置来定义自己的常量。或者，如果您想要更简化一点，则可以自己编辑.csproj并手动滚动一些具有各种定义的配置。

It is possible to hand roll this though. You can use the project configuration settings in Visual Studio to define your own constants. Or if you want it a little more streamline you can edit the .csproj yourself and hand roll some more configurations which have various defines.

例如，您可以制作您的项目文件如下图所示。我删除了一些信息，以使x86 / amd64信息更清晰。

For instance you can make your project file look like the following. I removed some of the information to make the x86/amd64 information clear.

  <PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Debug|x86' ">
    <!-- ... -->
    <DefineConstants>TRACE;DEBUG;X86</DefineConstants>
  </PropertyGroup>
  <PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Debug|amd64' ">
    <!-- ... -->
    <DefineConstants>TRACE;DEBUG;AMD64</DefineConstants>
    <ErrorReport>prompt</ErrorReport>
    <WarningLevel>4</WarningLevel>
  </PropertyGroup>

将此添加到.csproj文件中后，在项目中为我提供了2种新的平台配置。

Adding this to a .csproj file gives me 2 new platform configurations in my project.
