C#工程中 使用targets和props实例
描述:
需要使用的C++类库区分x64和x86版本,在C#工程编译时根据编译选项自动选择dll库版本并复制到输出路径
解决:
1.准备dll库编译好的两个版本;
2.在C#项目中引用随编一个(一般x64,x86引用文件都一致);
3.卸载该项目后,修改C#工程文件(*.csproj):
3.1 找到自动生成的引用节点
<Reference Include="CefSharp">
<HintPath>DLLs\x64\CefSharp.dll</HintPath>
</Reference>
3.2 添加引用条件 Condition=" '$(Platform)' == 'x64'"
<Reference Include="CefSharp" Condition=" '$(Platform)' == 'x64'">
<HintPath>DLLs\x64\CefSharp.dll</HintPath>
</Reference>
3.3 同理X86版本进行修改
<Reference Include="CefSharp" Condition=" '$(Platform)' == 'x86'">
<HintPath>DLLs\x86\CefSharp.dll</HintPath>
</Reference>
4.保存后重新加载该工程即可;
Note:
1.貌似也可以动态指定路径:
<Reference Include="CefSharp.Core">
<HintPath>DLLs\$(Platform)\CefSharp.Core.dll</HintPath>
</Reference>
2.添加自动复制脚本
2.1 添加targets文件,在该文件中定义所含目标文件(文件内容):
<?xml version="1.0" encoding="utf-8"?> <Project ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003"> <ItemGroup Condition="Exists('$(MSBuildThisFileDirectory)\DLLs\x86')"> <CefDlls32 Include="$(MSBuildThisFileDirectory)\DLLs\x86\*.*" /> </ItemGroup> <ItemGroup Condition="Exists('$(MSBuildThisFileDirectory)\DLLs\x64')"> <CefDlls64 Include="$(MSBuildThisFileDirectory)\DLLs\x64\*.*" /> </ItemGroup> </Project>
2.2 添加props文件,并在文件中写入复制信息以及路径:
<?xml version="1.0" encoding="utf-8"?> <Project ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003"> <Target Name="CefSharpCopyDlls86" BeforeTargets="AfterBuild" Condition="'$(Platform)' == 'x86'"> <Message Importance="high" Text="Copying cef.dlls x86 binaries" /> <Copy SourceFiles="@(CefDlls32)" DestinationFolder="$(TargetDir)" SkipUnchangedFiles="true" /> </Target> <Target Name="CefSharpCopyDlls64" BeforeTargets="AfterBuild" Condition="'$(Platform)' == 'x64'"> <Message Importance="high" Text="Copying cef.dlls x64 binaries" /> <Copy SourceFiles="@(CefDlls64)" DestinationFolder="$(TargetDir)" SkipUnchangedFiles="true" /> </Target> </Project>
2.3 在项目文件中导入两个文件,ok;
<Import Project="DLLs\CefDlls.Native.props" Condition="Exists('DLLs\CefDlls.Native.props')" />
<Import Project="Dlls\cef.dlls.targets" Condition="Exists('Dlls\cef.dlls.targets')" />
2.4 验证成功,编译输出信息;
