c# - 无法加载文件或程序集“msshrtmi”，系统找不到指定的文件

Question

我正在尝试将 Windows Azure 站点从云降级为网站。我收到此错误:

Could not load file or assembly 'msshrtmi, Version=1.7.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.

因为我不在云端，所以我需要这个程序集吗？我如何告诉网站不要寻找它？我已将这些引用添加到我的项目中:

Microsoft.WindowsAzure.CloudDriveMicrosoft.WindowsAzure.诊断Microsoft.WindowsAzure.ServiceRuntimeMicrosoft.WindowsAzure.StorageClient

在我的 WorkerRole.cs 类中，这是我的代码:

/// <summary>
/// Reads settings from service configuration file. 
/// </summary>
/// <param name="key">Setting key.</param>    
string AzureHelper_GetApplicationSettings(string key)
{
    try
    {
        return RoleEnvironment.GetConfigurationSettingValue(key);
    }
    catch
    {
        // Setting key was not found
        return null;
    }
}

Answer 1

删除这些引用(以及它们附带的所有代码):

• Microsoft.WindowsAzure.CloudDrive
• Microsoft.WindowsAzure.Diagnostics
• Microsoft.WindowsAzure.ServiceRuntime

这些程序集的大多数功能仅适用于云服务(Web/ worker 角色)。

现在您看到的错误似乎与读取配置有关:

Microsoft.WindowsAzure.ServiceRuntime.RoleEnvironment.GetConfigurationSettingValue(String configurationSettingName) +0 
AzureInit.AzureHelper_GetApplicationSettings(String key) +28

考虑更改 AzureHelper_GetApplicationSettings 中的代码以使用 Microsoft.WindowsAzure.ConfigurationManager NuGet 包。这允许您在 ServiceConfiguration.cscfg 和 Web.config (AppSettings) 之间自动切换。如果 RoleEnvironment.IsAvailable (= Cloud Service)，它将从 ServiceConfiguration.cscfg 中读取。如果不是(= 网站/虚拟机/本地)，它将从 AppSettings 中读取。但是，如果您部署到网站，则需要将 ServiceConfiguration.cscfg 中的设置添加到 web.config 中的 appSettings
