Question

protected OdbcConnection conectarBD()
{
    String StringDeConexion = "Data Source=PABLOZN\\SQLEXPRESS;Initial Catalog=Proyecto2;Integrated Security=True";

    try
    {
        OdbcConnection conexion = new OdbcConnection(StringDeConexion);
        conexion.Open();
        return conexion;
    }
    catch (Exception ex)
    {
        Label3.Text = ex.StackTrace.ToString();
        return null;
    }
}

问题是，当我浏览我的网站时，Label会在第18行显示此例外：

en System.Data.Odbc.OdbcConnection.HandleError（OdbcHandle hrHandle， RetCode retcode）en System.Data.Odbc.OdbcConnectionHandle..ctor（OdbcConnection连接， OdbcConnectionString constr，OdbcEnvironmentHandle environmentHandle） en System.Data.Odbc.OdbcConnectionOpen..ctor（OdbcConnection outerConnection，OdbcConnectionString connectionOptions）zh System.Data.Odbc.OdbcConnectionFactory.CreateConnection（DbConnectionOptions options，DbConnectionPoolKey poolKey，Object poolGroupProviderInfo， DbConnectionPool池，DbConnection owningObject）en System.Data.ProviderBase.DbConnectionFactory.CreateConnection（DbConnectionOptions options，DbConnectionPoolKey poolKey，Object poolGroupProviderInfo， DbConnectionPool池，DbConnection owningConnection， DbConnectionOptions userOptions）zh System.Data.ProviderBase.DbConnectionFactory.CreateNonPooledConnection（的DbConnection owningConnection，DbConnectionPoolGroup poolGroup，DbConnectionOptions userOptions）en System.Data.ProviderBase.DbConnectionFactory.TryGetConnection（的DbConnection owningConnection，TaskCompletionSource 1 retry, DbConnectionOptions userOptions, DbConnectionInternal oldConnection, DbConnectionInternal& connection) en System.Data.ProviderBase.DbConnectionInternal.TryOpenConnectionInternal(DbConnection outerConnection, DbConnectionFactory connectionFactory, TaskCompletionSource 1次重试，DbConnectionOptions userOptions）zh System.Data.ProviderBase.DbConnectionClosed.TryOpenConnection（的DbConnection outerConnection，DbConnectionFactory connectionFactory， TaskCompletionSource`1重试，DbConnectionOptions userOptions）en System.Data.ProviderBase.DbConnectionInternal.OpenConnection（的DbConnection outerConnection，DbConnectionFactory connectionFactory）en System.Data.Odbc.OdbcConnection.Open（）zh_cn index.conectarBD（）en c：.. \ Documents \ Visual Studio 2012 \ WebSites \ Proyecto \ index.aspx.cs：línea18

Answer 1

验证用户是否有权访问数据库。如何使用可信连接，验证当前用户是否可以访问数据库。如果您的应用程序是Web，请确保NETWORKSERVICE可以连接到数据库。

您还可以尝试在Windows ODBC管理器中通过DSN配置连接字符串。

OdbcConnection open（）不起作用
