RemovePackageAsync(String)

编辑

异步删除当前用户的包，并接收有关删除操作的进度和状态消息。如果没有为用户安装的其他包依赖于依赖依赖项包，则也会为用户删除依赖项包。

public:
 virtual IAsyncOperationWithProgress<DeploymentResult ^, DeploymentProgress> ^ RemovePackageAsync(Platform::String ^ packageFullName) = RemovePackageAsync;

/// [Windows.Foundation.Metadata.RemoteAsync]
IAsyncOperationWithProgress<DeploymentResult, DeploymentProgress> RemovePackageAsync(winrt::hstring const& packageFullName);

[Windows.Foundation.Metadata.RemoteAsync]
public IAsyncOperationWithProgress<DeploymentResult,DeploymentProgress> RemovePackageAsync(string packageFullName);

function removePackageAsync(packageFullName)

Public Function RemovePackageAsync (packageFullName As String) As IAsyncOperationWithProgress(Of DeploymentResult, DeploymentProgress)

参数

packageFullName: String
Platform::String

winrt::hstring

用于标识要删除的包的包标识的字符串表示形式。

IAsyncOperationWithProgress<DeploymentResult,DeploymentProgress>

部署请求的状态。 DeploymentResult 包含部署操作的最终返回值（完成后）。 DeploymentProgress 可用于获取整个部署操作过程中的完成百分比。

属性: RemoteAsyncAttribute

示例

调用 RemovePackageAsync (String) 方法来卸载应用包。请注意， packageFullName 中的包 全名来自命令行参数。

RemovePackageAsync (String) 返回可用于管理异步操作的对象。使用 Completed 属性设置委托。检查 Status 属性以确定部署操作的状态。如果状态为 “错误”，则示例调用 GetResults 方法以获取其他错误信息。

using Windows.Foundation;
using Windows.Management.Deployment;

[STAThread]
public static int Main(string[] args)
{
    string inputPackageFullName = args[0];
    int returnValue = 0;

    PackageManager packageManager = new Windows.Management.Deployment.PackageManager();

    IAsyncOperationWithProgress<DeploymentResult, DeploymentProgress> deploymentOperation = 
        packageManager.RemovePackageAsync(inputPackageFullName);
    // This event is signaled when the operation completes
    ManualResetEvent opCompletedEvent = new ManualResetEvent(false); 

    // Define the delegate using a statement lambda
    deploymentOperation.Completed = (depProgress, status) => { opCompletedEvent.Set(); };

    // Wait until the operation completes
    opCompletedEvent.WaitOne();

    // Check the status of the operation
    if (deploymentOperation.Status == AsyncStatus.Error)
    {
        DeploymentResult deploymentResult = deploymentOperation.GetResults();
        Console.WriteLine("Error code: {0}", deploymentOperation.ErrorCode);
        Console.WriteLine("Error text: {0}", deploymentResult.ErrorText);
        returnValue = 1;
    }
    else if (deploymentOperation.Status == AsyncStatus.Canceled)
    {
        Console.WriteLine("Removal canceled");
    }
    else if (deploymentOperation.Status == AsyncStatus.Completed)
    {
        Console.WriteLine("Removal succeeded");
    }
    else
    {
        returnValue = 1;
        Console.WriteLine("Removal status unknown");
    }

    return returnValue;
}

注解

若要成功调用此方法，调用方需要满足以下条件之一：

调用方在 AppContainer (低 IL) 中运行，并且具有 packageManagement 受限功能。
调用方正在运行的 IL 为中或更高。
调用方发布者与要删除的包 (或卷) 的发布者匹配。

有关上述术语的说明以及指向详细信息的链接，请参阅打包、部署和处理。

无法取消此请求。包全名是包标识的一种替代形式，较短，适合命名对象，如文件和目录。包标识由包清单的 Identity 元素表示。删除包时，当前用户将删除该包，这意味着，如果其他用户已安装该包，包有效负载将继续存在，但当前用户无法访问该包。如果没有其他用户安装指定的包，则其有效负载将从 %ProgramFiles%\WindowsApps 目录中删除。与要删除的包关联的任何应用都将作为删除包的一部分自动关闭。
