C# 正在设置Azure portal以使用connectionString作为应用程序设置，而不使用代码

我对Azure和Web开发相对较新，我正试图找到一种从Web应用服务的Configuraton blade使用connectionString的方法。我的理解是，我应该能够使用门户的连接字符串而不是我在Web.Config中指定的伪值来覆盖connectionString。我希望在不更改源代码的情况下执行此操作

我已经在门户中添加了连接字符串，如下所示：

<configuration>
  <configSections>
    <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=xxxxxxxxxxxx" requirePermission="false" />
    <!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 -->

    <section name="configBuilders" type="System.Configuration.ConfigurationBuildersSection, System.Configuration, Version=4.0.0.0, Culture=neutral, PublicKeyToken=xxxxxxxxxxxx" restartOnExternalChanges="false" requirePermission="false" />

  </configSections>

  <configBuilders>
    <builders>
      <add name="AzureKeyVault" vaultName="xxxxxxxxxxxx" type="Microsoft.Configuration.ConfigurationBuilders.AzureKeyVaultConfigBuilder, Microsoft.Configuration.ConfigurationBuilders.Azure, Version=1.0.0.0, Culture=neutral" vaultUri="https://xxxxxxxxxxxx.vault.azure.net/" />
    </builders>
  </configBuilders>

  <!--<connectionStrings>
    <add name="SchoolContext" connectionString="Data Source=(LocalDb)\v11.0;Initial Catalog=ContosoUniversity2;Integrated Security=SSPI;" providerName="System.Data.SqlClient" />
  </connectionStrings>-->
  <!--Azure connection string-->
  <connectionStrings>
    <add name="SchoolContext" connectionString="thisdoesntmatter" providerName="System.Data.SqlClient" />
    <!-- <add name="ContosoUniversityLogin" connectionString="metadata=res://*/LoginData.csdl|res://*/LoginData.ssdl|res://*/LoginData.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=XXX.database.windows.net;initial catalog=ContosoUniversity;persist security info=True;user id=XXX;password=XXX;MultipleActiveResultSets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient" />
   -->
  </connectionStrings>
  <appSettings>
    <add key="webpages:Version" value="3.0.0.0" />
    <add key="webpages:Enabled" value="false" />
    <add key="ClientValidationEnabled" value="true" />
    <add key="UnobtrusiveJavaScriptEnabled" value="true" />
    <add key="connectionString" value="dummy" />
  </appSettings>

我希望这足以覆盖源代码中提供的connectionString

我的Web.Config文件如下所示：

<configuration>
  <configSections>
    <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=xxxxxxxxxxxx" requirePermission="false" />
    <!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 -->

    <section name="configBuilders" type="System.Configuration.ConfigurationBuildersSection, System.Configuration, Version=4.0.0.0, Culture=neutral, PublicKeyToken=xxxxxxxxxxxx" restartOnExternalChanges="false" requirePermission="false" />

  </configSections>

  <configBuilders>
    <builders>
      <add name="AzureKeyVault" vaultName="xxxxxxxxxxxx" type="Microsoft.Configuration.ConfigurationBuilders.AzureKeyVaultConfigBuilder, Microsoft.Configuration.ConfigurationBuilders.Azure, Version=1.0.0.0, Culture=neutral" vaultUri="https://xxxxxxxxxxxx.vault.azure.net/" />
    </builders>
  </configBuilders>

  <!--<connectionStrings>
    <add name="SchoolContext" connectionString="Data Source=(LocalDb)\v11.0;Initial Catalog=ContosoUniversity2;Integrated Security=SSPI;" providerName="System.Data.SqlClient" />
  </connectionStrings>-->
  <!--Azure connection string-->
  <connectionStrings>
    <add name="SchoolContext" connectionString="thisdoesntmatter" providerName="System.Data.SqlClient" />
    <!-- <add name="ContosoUniversityLogin" connectionString="metadata=res://*/LoginData.csdl|res://*/LoginData.ssdl|res://*/LoginData.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=XXX.database.windows.net;initial catalog=ContosoUniversity;persist security info=True;user id=XXX;password=XXX;MultipleActiveResultSets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient" />
   -->
  </connectionStrings>
  <appSettings>
    <add key="webpages:Version" value="3.0.0.0" />
    <add key="webpages:Enabled" value="false" />
    <add key="ClientValidationEnabled" value="true" />
    <add key="UnobtrusiveJavaScriptEnabled" value="true" />
    <add key="connectionString" value="dummy" />
  </appSettings>

门户中存储的连接字符串如下：（为了安全起见，删除了ID和密码）：

---

Server=tcp:XXX.database.windows.net，1433；初始目录=康托索大学；持久安全信息=False；用户ID=XXX；密码=XXX；MultipleActiveResultSets=False；加密=真；TrustServerCertificate=False；连接超时=30

您在门户中创建的连接字符串名为

connectionString

，这是您想要的吗？我在您的配置中没有看到任何名为that的连接字符串。我看到一个名为

connectionString

的appsetting，但appsettings与连接字符串是分开的。修复了！这篇文章很有帮助：名字是SchoolContext而不是connectionString。我以为连接字符串的名称是appSettings下Web.Config中的connectionString，但实际上是SchoolContextPlease添加此作为答案，因为它将帮助其他具有相同问题的人。
