Visual studio 更改TeamCity内app.config中的值

在包含所有单元测试的VisualStudio解决方案中，我们有一些文本文件。这些文本文件是根据单元测试生成的一些结果进行检查的

为了加载文件，我们有一个app.config，其中包含：

 <appSettings>
    <add key="BaseTestDataPath" value="D:\MyPath\MySolution\" />
 </appSettings>

我知道代理工作文件夹中的物理布局，因此我需要知道的是：

• 如何在针对TeamCity的“我的构建步骤”中的解决方案运行Nunit之前更改app.config文件

---

有几种方法可以实现这一点

在运行NUnit步骤之前，只需选择以下脚本之一，将其添加到源代码管理中，并在构建配置中设置PowerShell构建运行程序，以运行传递所需参数的脚本。如果你选择了选项二，那么你也需要考虑变换DLL。 AppSettingReplace.ps1 如果您只想更改一个值，那么可以使用一些简单的PowerShell实现这一点，它将配置文件加载到xml文档中，迭代应用程序设置并更改匹配的设置

    [ValidateNotNullOrEmpty()]
    [string] $ApplicationSetting = $(throw "-ApplicationSetting is mandatory, please provide a value."),

    $CurrentScriptVersion = "1.0"

    Write-Host "================== Config Transform - Version"$CurrentScriptVersion": START =================="

    # Log input variables passed in
    Log-Variables
    Write-Host

    try {
        $xml = [xml](get-content($ConfigurationFile))
        $conf = $xml.configuration
        $conf.appSettings.add | foreach { if ($_.key -eq $ApplicationSetting) { $_.value = $ApplicationSettingValue } }
        $xml.Save($ConfigurationFile)
    } 
    catch [System.Exception] {
        Write-Output $_
        Exit 1
    }

    Write-Host "================== Config Transform - Version"$CurrentScriptVersion": END =================="
}

function Log-Variables
{
    Write-Host "ConfigurationFile: " $ConfigurationFile
    Write-Host "ApplicationSetting: " $ApplicationSetting
    Write-Host "ApplicationSettingValue: " $ApplicationSettingValue
    Write-Host "Computername:" (gc env:computername)
}

Main

用法

AppSettingReplace.ps1“D:\MyPath\app.config”“BaseTestDataPath”“%teamcity.build.workingDir%”

XDTConfigtTransform.ps1 另一种方法是使用XDT提供完整的配置转换支持—这确实需要Microsoft.Web.XmlTransform.dll以某种方式在服务器上结束（我通常将其放入源代码管理中）

下面的脚本将用另一个配置文件转换一个配置文件

    }
    if (!$TransformFile -or !(Test-Path -path $TransformFile -PathType Leaf)) {
        throw "File not found. $TransformFile";
        Exit 1
    }

    try {

        Add-Type -LiteralPath "$LibraryPath\Microsoft.Web.XmlTransform.dll"
        $xml = New-Object Microsoft.Web.XmlTransform.XmlTransformableDocument;
        $xml.PreserveWhitespace = $true
        $xml.Load($ConfigurationFile);

        $xmlTransform = New-Object Microsoft.Web.XmlTransform.XmlTransformation($TransformFile);
        if ($xmlTransform.Apply($xml) -eq $false)
        {
            throw "Transformation failed."
        }
        $xml.Save($ConfigurationFile)
    }

用法

XDTConfigtTransform.ps1“D:\MyPath\app.config”D:\MyPath\app.transform.config”“%teamcity.build.workingDir%\Library”

注意：最后一个参数是包含Microsoft.Web.XmlTransform.dll的目录的路径

希望这有帮助

您可以在生成之前使用生成功能在文本文件中执行正则表达式替换。生成后，它会将文件内容恢复到原始状态。

您也可以选择使用nuget package id=“SlowCheetah”。这为app.config添加了转换。

在构建时进行转换，因此不需要额外的脚本或DLL。

谢谢，这正是我要寻找的，您需要更多+1的答案；）虽然您可以添加这个NuGet包，但它最终只对TC是必需的，所以在解决方案中使用它本身并不是必需的。因此，这仍然意味着要搞乱特定的TC实现。这似乎与运行单独的脚本没有什么不同？它有助于在pc上进行测试。我有app.config.Debug、app.config.UAT、app.config.Release等。通过构建解决方案，它得到了转换，因此可以测试不同的服务器、数据库、，etc开箱即用，不需要任何额外的脚本。你有一个例子说明如何使用FCR来解决这个问题吗？
