在Transaction中调用CommandBuilder总是提示Transaction属性尚未初始化，why？

Question

当分配给命令的连接处于挂起的本地事务中时，命令必须具有事务对象才能执行。该命令的 Transaction 属性尚未初始化。

Answer 1

//call CommandBuilder
            OleDbCommandBuilder cCmdBuilder = new OleDbCommandBuilder(cAdapter);
            Trace.Write("正确");
            cAdapter.UpdateCommand = cCmdBuilder.GetUpdateCommand();
            Trace.Write("正确");
            cAdapter.InsertCommand = cCmdBuilder.GetInsertCommand();
            cAdapter.DeleteCommand = cCmdBuilder.GetDeleteCommand();
            //end CommandBuilder
            Trace.Write("正确");
            cAdapter.Update(cDataSet, "Employees");
在调用cAdapter.UpdateCommand = cCmdBuilder.GetUpdateCommand();
时候出现上述错误。

.net 最好去.net 专区问.
