Question

我正在尝试通过IIS连接到我的计算机中的DSN。我的代码就像这样

  internal class ODBCClass:IDisposable
    {
        private readonly OdbcConnection oConnection;

        private OdbcCommand oCommand;

        public ODBCClass(string DataSourceName)
        {
//Instantiate the connection
            oConnection = new OdbcConnection("Dsn=" + DataSourceName);
            try
            {
//Open the connection
                oConnection.Open();
//Notify the user that the connection is opened
                Console.WriteLine("The connection is established with the database");
            }
            catch (OdbcException caught)
            {
                Console.WriteLine(caught.Message);
                Console.Read();
            }
        }

        public void CloseConnection()
        {
            oConnection.Close();
        }

        public OdbcCommand GetCommand(string Query)
        {
            oCommand = new OdbcCommand();
            oCommand.Connection = oConnection;
            oCommand.CommandText = Query;
            return oCommand;
        }

        public void Dispose()
        {
            oConnection.Close();
        }
    }
public DataSet GetOrderData()
    {
        using (var o = new ODBCClass("TL"))
        {
            OdbcCommand oCommand = o.GetCommand("select * from Department");
            var oAdapter = new OdbcDataAdapter(oCommand);
            var ds = new DataSet();
            oAdapter.Fill(ds);
            //TO DO : Make use of the data set
            return ds;
        }
    }

当我通过VisualStudio作为控制台应用程序运行时，这可以正常工作。但是当我将它托管到IIS并尝试运行时，它会抛出这样的错误

System.Data.Odbc.OdbcException: ERROR [28000] [Microsoft][SQL Server Native Client 11.0][SQL Server]Login failed for user &#39;WORKGROUP\vg$&#39;.

确保使用系统DSN，而不是用户DSN。也尝试传递用户名和密码。 http://www.carlprothman.net/Technology/ConnectionStrings/ODBCDSN/tabid/89/Default.aspx

您可能还想尝试使用无DSN连接 http://www.carlprothman.net/Technology/ConnectionStrings/ODBCDSNLess/tabid/90/Default.aspx

对于较旧的SQL Server版本，您可以使用＆＃34; OLE DB Provider for SQL Server＆＃34; http://www.carlprothman.net/Default.aspx?tabid=87#OLEDBProviderForSQLServer

对于较新的SQL Server版本，请使用＆＃34; Microsoft SQL Server .NET数据提供程序＆＃34; http://www.carlprothman.net/Default.aspx?tabid=86#SQLClientManagedProvider
