dataset  数据集为填充

@沅江: 填充的时候加个lock试试

@chenping2008: 

 public static DataSet GreatDs(string sql)
    {
       
        try
        {
            lock (lockobj)
            {

                openConn();
                OleDbDataAdapter Dar = new OleDbDataAdapter(sql, myconn);
                DataSet ds = new DataSet();
                Dar.Fill(ds);
                return ds;
            }
        }
        catch (Exception)
        {
            throw;
         
        }
        finally
        {
            myconn.Dispose();
            if (myconn.State != ConnectionState.Closed)
            {
                myconn.Close();
            }
        }
    }

我是这样写的   你帮我看下   咋还是不行啊  在本地行  在服务器上不行

@沅江: Dar 也在finally中释放一下

@chenping2008: 这样加了  反应好慢哦  

@沅江: 谢谢哦 ！解决了    好久没有来过了哦 ~_~
