问题描述

如何在窗口应用程序中同时打开multy oledbdatareader.

how can open multy oledbdatareader at same time in window application.

推荐答案

我猜您正在尝试打开两个或多个共享相同实例的DataReader实例. DbConnection.不支持此功能.每个DbConnection仅支持一个打开的DataReader.
1.)完成第一个阅读器的工作，然后关闭它，然后再打开第二个阅读器
2.)为第二个阅读器打开一个单独的连接

i guess you are trying to open two or more DataReader instances that share the same instance of DbConnection. This is not supported. Only one opened DataReader per DbConnection is supported.
1.) Finish the work of reader one and close it prior to open the second reader
2.) open a seperate connection for the second reader
