從Web服務向SQL Server 2008數據庫發佈數據會產生錯誤

Question

我正在嘗試使用c＃將數據發佈到Web服務（我寫的）。當我從本地機器運行它時，該Web服務運行良好。當我移動到它的服務器（我的建築內），它拋出這個錯誤：

Server was unable to process request.
---> ExecuteNonQuery: Connection property has not been initialized.

任何想法可能會導致什麼呢？

我已經檢查：

Answer 1

好像連接沒有被使用的命令對象相關聯。

檢查並確認創建連接對象是否存在問題。它是否正確初始化？它是否使用正確的連接字符串？

Answer 2

Connection property has not been initialized通常由Connection對象引起，原因是ConnectionString未提供或不正確的信息。

using (SqlConnection connection = new SqlConnection()) 
{ 
    // don't forget this line. 
    connection.ConnectionString = "valid connection string here"; 
    // then pass the connection to your command object 
    using (SqlCommand command = new SqlCommand()) 
    { 
     command.Connection = connection; 
     // other codes 
    } 
}

我能解決我的問題。我實際上是對錯誤的服務器進行身份驗證。所以一旦我指出正確的服務器，它的工作。駕駛艙麻煩在這裏。
