--------代码下.有关闭数据库连接了还是会出现这种错误-----------
public void Close()
{
if (conn != null)
{
conn.Close();
conn.Dispose();
}
}
public DataRow ExectueDataRow(string strsql)
{
DataSet ds = null;
try
{
Open();
da = new OleDbDataAdapter(strsql, conn);
ds = new DataSet();
da.Fill(ds);
}
catch (Exception exception1)
{
throw exception1;
}
finally
{
Close();
}
if (ds.Tables[0].Rows.Count < 1)
{
return null;
}
return ds.Tables[0].Rows[0];
}

本地测试一切正常..怎么样都没有出错..就上传服务器..出现这种错误..
#region 上一条产品内容
public DataRow Get_Panl_PubList(int PubListID)
{
string sql = string.Format("select top 1 * from PubList where PubListID<{0} order by PubListID desc", PubListID);
return db.ExectueDataRow(sql);
}
#endregion

#region 下一条产品内容
public DataRow Get_Next_PubList(int PubListID)
{
string sql = string.Format("select top 1 * from PubList where PubListID>{0}", PubListID);
return db.ExectueDataRow(sql);
}
#endregion
