使用Azure上托管的Web應用程序訪問本地SQL數據庫

Question

我正在嘗試從Azure托管的服務訪問公司場所中存在的SQL數據庫。 這是我嘗試過的：

1. 在本地服務器上創建MS SQL數據庫
2. 創建了示例Web應用程序（Windows Azure Cloud Service）
3. 修改web.config文件以具有正確的SQL連接字符串
4. 使用Azure管理門戶中的激活令牌激活Web角色
5. 在本地服務器上安裝本地端點
6. 將Web應用程序發布到Azure
7. 使用Web角色和ocal端點創建端點組
8. 啟動應用程序
9. 試圖從數據庫中獲取記錄。

嘗試使用Azure從數據庫中獲取記錄時出現以下錯誤：

System.Data.SqlClient.SqlException (0x80131904): A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)

請幫忙。

Trusted_Connection必須為false。 您不能從Azure執行Windows身份驗證。
