csproj财产状况

Question

我想添加一个带有条件的属性到csproj文件.

条件是:如果网络位置可用,我的属性应具有该值,否则为另一个位置.

任何提示？

谢谢,Horea

您可以使用静态方法System.Net.NetworkInformation.NetworkInterface.GetIsNetworkAvailable.

不幸的是,我认为您不能直接从Chose条件调用此静态方法来设置PropertyGroup.您可能需要编写自定义内联MSBuild任务来为您执行此操作.

<?xml version="1.0" encoding="utf-8"?>
<Project 
    ToolsVersion="4.0"
    xmlns="http://schemas.microsoft.com/developer/msbuild/2003"
    InitialTargets="Test"
    DefaultTargets="Test"
    >
      <Choose>
        <When Condition="$(IsConnected) == 'True'">
            <PropertyGroup>
                <ConnectMessage>You are connected</ConnectMessage>  
            </PropertyGroup>
        </When>

        <Otherwise>
            <PropertyGroup>
                <ConnectMessage>You are NOT connected</ConnectMessage>
            </PropertyGroup>
        </Otherwise>

      </Choose>


      <UsingTask 
        TaskName="GetConnectionStatus" 
        TaskFactory="CodeTaskFactory"
        AssemblyFile="$(MSBuildToolsPath)\Microsoft.Build.Tasks.v4.0.dll">

        <ParameterGroup>
          <IsConnected ParameterType="System.String" Output="true" />
        </ParameterGroup>
        <Task>
          <Code Type="Fragment" Language="cs">
            IsConnected = System.Net.NetworkInformation.NetworkInterface.GetIsNetworkAvailable().ToString();
          </Code>
        </Task>
      </UsingTask>


    <Target Name="Initialize">

        <GetConnectionStatus>
          <Output PropertyName="IsConnected" TaskParameter="IsConnected" />
        </GetConnectionStatus>

        <PropertyGroup>
            <ConnectMessage Condition="$(IsConnected) == 'True'">You Are Connected</ConnectMessage>
        </PropertyGroup>

        <Message Text="ConnectionStatus $(IsConnected)"/> 
        <Message Text="$(ConnectMessage)"/>
    </Target>

    <Target Name="Test" DependsOnTargets="Initialize">

        <Message Text="$(ConnectMessage)"/>

    </Target>
</Project>
