实现packageManager.AddPackageAsync时出错 [英] Error while implementing packageManager.AddPackageAsync

问题描述

你好，

我打算使用后台应用程序（UWP）安装Application。我的代码看起来像这样：

  private static async Task InstallPackageAsync（string packagePath）

        {

            Debug.WriteLine（" Install Package"）;

            string fullNamePackage =" cd08eb5f-bd86-4694-96c8-5d8e9fb32eed_jfasm645wnjtr" ;;

            var packageManager = new PackageManager（）;

            var packages = packageManager.FindPackagesForUser（string.Empty）.ToList（）;

            Debug.WriteLine（" packages：" + packages [0]）;

            URI packageUri =新URI（" C：\\Users\\mahes\\CityTireTimeClock_1.0.2.0_ARM_Debug.appx的"）;

         ;     VAR updateInsteadOfInstall = packages.Any（P => p.Id.FullName == fullNamePackage）;

          &NBSP ; if（updateInsteadOfInstall）

            {

               的Debug.WriteLine（[更新安装软件包"）;

解决方案

您好  mahesh_Pochamreddy，

>>> 我打算使用后台应用程序（UWP）安装应用程序

所以我假设您正在运行
后台应用程序。在Windows IoT Core上有这样的路径：  C：\ Users。正确的路径是C：\ Data \Users。

>>> 抛出异常：System.Private.CoreLib.dll中的'System.Exception'

WinRT信息：错误0x80070003：从位置打开包 

由于我上面说的无效文件路径导致此错误。

>>> 串fullNamePackage = QUOT; cd08eb5f-bd86-4694-96c8-5d8e9fb32eed_jfasm645wnjtr英寸;

完整的包名称中包含这样的版本信息：  db0c5c3b-d107-435a-A257-a26fa8f966d2_1.0.0.0_arm__a48w6404kk2ea

下面的代码对我的作品。你可以尝试一下：

 private static async Task InstallPackageAsync（）
 {
 Debug.WriteLine（" Install Package"）; 
 string fullNamePackage =" db0c5c3b-d107-435a-a257-a26fa8f966d2_1.0.0.0_arm__a48w6404kk2ea" ;; 
 var packageManager = new PackageManager（）; 
 var packages = packageManager.FindPackagesForUser（string.Empty）.ToList（）; 
 Debug.WriteLine（" packages：" + packages [0]）; 
 var updateInsteadOfInstall = packages.Any（p => p.Id.FullName == fullNamePackage）; 
如果（updateInsteadOfInstall）
 {
乌里packageUri =新URI（" C：\\Data\\Users\\DefaultAccount\\updateTest\\\ \\CityTireTimeClock_1.0.1.0_x86_x64_arm_Debug.appxbundle"）; 
 Debug.WriteLine（" update Install Package"）; 
 var result = await packageManager.UpdatePackageAsync 
（packageUri，null，DeploymentOptions.ForceApplicationShutdown）; 
} 
 else 
 {
 Uri packageUri = new Uri（" C：\\Data\\Users\\DefaultAccount\\CityTireTimeClock_1。 0.0.0_x86_x64_arm_Debug.appxbundle"）; 
 Debug.WriteLine（" else Install Package"）; 
 await packageManager.AddPackageAsync 
（packageUri，null，DeploymentOptions.ForceApplicationShutdown）; 
} 
} 

我放在路径下的第一个版本：C：\ Data\Users \DefaultAccount。

我放在路径下的更新包：  C：\ Data \ Users\DefaultAccount\updateTest。

确保添加包管理功能：

 xmlns：rescap = " HTTP：//schemas.microsoft.com/appx/manifest/foundation/windows10/restrictedcapabilities" 
 IgnorableNamespaces =" uap mp iot rescap"> 
 
 // ... ... 
 
< rescap：Capability Name =" packageManagement" /> 

如果有帮助请告诉我。

祝你好运，

Hello,

I am planning to install Application using background application (UWP). my code looks like this:

  private static async Task InstallPackageAsync(string packagePath)
        {
            Debug.WriteLine("Install Package");
            string fullNamePackage = "cd08eb5f-bd86-4694-96c8-5d8e9fb32eed_jfasm645wnjtr";
            var packageManager = new PackageManager();
            var packages = packageManager.FindPackagesForUser(string.Empty).ToList();
            Debug.WriteLine("packages :"+ packages[0]);
            Uri packageUri = new Uri("C:\\Users\\mahes\\CityTireTimeClock_1.0.2.0_ARM_Debug.appx");
            var updateInsteadOfInstall = packages.Any(p => p.Id.FullName == fullNamePackage);
            if (updateInsteadOfInstall)
            {
                Debug.WriteLine(" update Install Package");

Hello mahesh_Pochamreddy,

>>>I am planning to install Application using background application (UWP)

So I assume you running the background application on Windows IoT Core device. While on Windows IoT Core there is on such path: C:\Users. The right path will be C:\Data\Users.

>>>Exception thrown: 'System.Exception' in System.Private.CoreLib.dll
WinRT information: error 0x80070003: Opening the package from location 

This error caused by the invalid file path like I said above.

>>>string fullNamePackage = "cd08eb5f-bd86-4694-96c8-5d8e9fb32eed_jfasm645wnjtr";

The full package name contains version information like this: db0c5c3b-d107-435a-a257-a26fa8f966d2_1.0.0.0_arm__a48w6404kk2ea.

The following code works for me. You can have a try:

        private static async Task InstallPackageAsync()
        {
            Debug.WriteLine("Install Package");
            string fullNamePackage = "db0c5c3b-d107-435a-a257-a26fa8f966d2_1.0.0.0_arm__a48w6404kk2ea";
            var packageManager = new PackageManager();
            var packages = packageManager.FindPackagesForUser(string.Empty).ToList();
            Debug.WriteLine("packages :" + packages[0]);
            var updateInsteadOfInstall = packages.Any(p => p.Id.FullName == fullNamePackage);
            if (updateInsteadOfInstall)
            {
                Uri packageUri = new Uri("C:\\Data\\Users\\DefaultAccount\\updateTest\\CityTireTimeClock_1.0.1.0_x86_x64_arm_Debug.appxbundle");
                Debug.WriteLine(" update Install Package");
                var result = await packageManager.UpdatePackageAsync
                    (packageUri, null, DeploymentOptions.ForceApplicationShutdown);
            }
            else
            {
                Uri packageUri = new Uri("C:\\Data\\Users\\DefaultAccount\\CityTireTimeClock_1.0.0.0_x86_x64_arm_Debug.appxbundle");
                Debug.WriteLine(" else Install Package");
                await packageManager.AddPackageAsync
                   (packageUri, null, DeploymentOptions.ForceApplicationShutdown);
            }
        }

The first version I put under path: C:\Data\Users\DefaultAccount.

The update package I put under path: C:\Data\Users\DefaultAccount\updateTest.

Make sure add package management capability:

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

//...

<rescap:Capability Name="packageManagement" />

Please let me know if it helps.

Rita
