我想使用Powershell更新XML文件。我想将ServiceManifestVersion更新为某个值

设置该值时，出现以下错误：

在此对象上找不到属性“ServiceManifestVersion”。 验证该属性是否存在并可以设置

如果我只保留一个节点，但在foreach循环上运行时出错，那么我可以更新值。此外，我可以获取值，但不能设置它。任何帮助都将不胜感激。

VSTS人员为此有一些任务。他们是。您可以直接在VST或TFS中使用任务，也可以在您自己的解决方案中使用代码。（这是麻省理工学院许可的）

将您的foreach更改为：

foreach ($ServiceManifestRef in $ApplicationManifestXml.ApplicationManifest.ServiceManifestImport.ServiceManifestRef)
{
    $ServiceManifestRef.SetAttribute('ServiceManifestVersion', $updatedVersionNumber)
}

这也会有所帮助。我需要做一些调整，它与竹子的工作，但它会帮助我了。谢谢你的帮助：）那也会有帮助的。我需要做一些调整，它与竹子的工作，但它会帮助我了。感谢您的帮助：）
