I want to get the list of installed uwp application in the desktop.I want to make it within uwp application.Is there any way to achieve this?

推荐答案

我们可以使用 PackageManager.FindPackagesForUser(String) 方法在 UWP 应用中查找为当前用户安装的所有包，如下所示:

We can use PackageManager.FindPackagesForUser(String) method to find all packages installed for for the current user in UWP apps like following:

PackageManager packageManager = new PackageManager();

IEnumerable<Windows.ApplicationModel.Package> packages = packageManager.FindPackagesForUser("");

此方法返回一个可枚举的集合 包 对象.每个 Package 对象此集合包含有关程序包的信息，包括但不限于其名称、发布者、版本和安装位置.

This method returns an enumerable collection of Package objects. Each Package object in this collection contains information about the package, including but not limited to its name, publisher, version, and install location.

但请注意，要在 UWP 应用中使用此方法，我们需要在应用的包清单中声明受限功能 packageQuery.

But please note that To use this method in a UWP app, we need to declare restricted capability packageQuery in app's package manifest.

<Package
  xmlns="http://schemas.microsoft.com/appx/manifest/foundation/windows10"
  xmlns:mp="http://schemas.microsoft.com/appx/2014/phone/manifest"
  xmlns:uap="http://schemas.microsoft.com/appx/manifest/uap/windows10"
  xmlns:rescap="http://schemas.microsoft.com/appx/manifest/foundation/windows10/restrictedcapabilities"
  IgnorableNamespaces="uap mp rescap">

  ...

  <Capabilities>
    <Capability Name="internetClient" />
    <rescap:Capability Name="packageQuery" />
  </Capabilities>
</Package>
