ASP.NET无法将数据输入数据库

Question

I recently uploaded my data driven ASP.NET application to a asp hosting service called SmarterAsp.com.

Everything in the website works fine, all but 1 feature, data can't be entered into the database.

However when using a gridview control to see data in the database the data is displayed perfectly and I can even insert, update and delete data through the gridview.

I uploaded my database in a separate space on the hosting service and I was provided with a connection string, I replaced all connection strings in my application with the provided connection string.

It works fine in my IDE, the problem only came once I uploaded the website to the hosting service.

Here is my C# code for inserting data into my database:

protected void Button1_Click(object sender, EventArgs e)
{
        using (SqlConnection connection = new SqlConnection(@DataSource=SQL5004.Smarterasp.net;Initial Catalog=DB_9DE115_hmkdatabase;User Id=DB_9DE115_hmkdatabase_admin;Password=YOUR_DB_PASSWORD;"))
        {
            SqlCommand cmd = new SqlCommand(@"INSERT INTO Clients(ClientName)VALUES(@ClientName)");
            cmd.CommandType = CommandType.Text;
            cmd.Connection = connection;
            cmd.Parameters.AddWithValue("@ClientName", TextBox1.Text.ToString());
            connection.Open();
            cmd.ExecuteNonQuery();
        }
}

And here is the error I get when attempting to insert the data: Server Error in '/' Application.

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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)

Description:

An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details:

System.Data.SqlClient.SqlException: 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: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)

My first thought was that it's a problem with the connection string, but the connection string works fine with the rest of the application. I can enter data into my database through the gridview add function but I cannot enter data using the C# codebehind page. As I said it works fine in my IDE, the problem only came once I uploaded the website to the hosting service.

Thanks in advance for the help guys. You guys are real life heroes!

Answer 1

I sorted out the problem. My problem was where I initialized the connection string and where I opened the connection. I initialized the connection string at the top where the page is initialized. And then replaced where the connection string was with connection.open();

Thanks for all the help guys!
