CloudConfigurationManager.GetSetting 返回 null [英] CloudConfigurationManager.GetSetting returning null

问题描述

按照说明此处我有:

var connectionString = CloudConfigurationManager.GetSetting("StorageConnectionString");

但是connectionString 是null，这是我的app.config:

But connectionString is null, here is my app.config:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <startup>
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
  </startup>
  <connectionStrings>
    <add name="StorageConnectionString"
         connectionString="DefaultEndpointsProtocol=https;AccountName=storage;AccountKey=key" />
  </connectionStrings>
  <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="Microsoft.Data.OData" publicKeyToken="31bf3856ad364e35" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-5.2.0.0" newVersion="5.2.0.0" />
      </dependentAssembly>
    </assemblyBinding>
  </runtime>
</configuration>

推荐答案

这很好用，即使评论不合适，因为我确实有对 CloudConfigManager 的引用:

Well this works, even if the comment doesn't fit, because I do have a ref to CloudConfigManager:

如果您正在创建一个不引用 Microsoft.WindowsAzure.CloudConfigurationManager 的应用程序，并且您的连接字符串位于 web.config 或 app.config 中，如上所示，那么您可以使用 ConfigurationManager 来检索连接字符串.您需要在项目中添加对 System.Configuration.dll 的引用，并为其添加另一个命名空间声明:

If you are creating an application with no reference to Microsoft.WindowsAzure.CloudConfigurationManager, and your connection string is located in the web.config or app.config as show above, then you can use ConfigurationManager to retrieve the connection string. You will need to add a reference to System.Configuration.dll to your project and add another namespace declaration for it:

using System.Configuration;

CloudStorageAccount storageAccount = CloudStorageAccount.Parse(
    ConfigurationManager.ConnectionStrings["StorageConnectionString"].ConnectionString);
