未清除asp.net数据库会话

我正在使用sqldatasource连接asp.net中的oracle数据库，这是我的连接字符串

<add name="ConnectionString3" connectionString="Data Source=sml; User ID=sml; Password=sml; Unicode=True; Pooling=False;" providerName="System.Data.OracleClient"/>

你试过c#“using”语法吗

此处有更多详细信息：

您是否已检查oracle中连接已锁定的用户。试着探索一下。它可以给你一些想法。你应该使用try、catch、finally或@Geg Smithusing建议的try-catch。一个会话已删除，但存在一个处于锁定状态的sill-one。会话为何变为锁定状态？你是否也使用事务？如果你使用try，catch和in finally如果要在finally块中关闭连接，则不应该有任何锁定会话。Asp.net本身执行连接池。意味着它不会关闭所有连接，它会为下一个请求保留一些打开的连接。但在这种情况下，它也不应该被锁定。

 Dim con = New OleDbConnection("Data Source=sml; User ID=sml; Password=sml; provider=OraOLEDB.Oracle; Pooling=false")
