the problem is in DataSet.xsd file with TableAdapter's connection string which you've added in Dataset by drag and drop. 问题出在带有TableAdapter的连接字符串的DataSet.xsd文件中，您已经通过拖放将其添加到了Dataset中。

open DataSet.xsd file in xml editor 在xml编辑器中打开DataSet.xsd文件
remove connection string which have property AppSettingsObjectName="web.config" 删除具有属性AppSettingsObjectName =“ web.config”的连接字符串
again open the Dataset with normal editor. 再次使用普通编辑器打开数据集。
now delete the TableAdapter which you have added by drag and drop 现在删除通过拖放添加的TableAdapter
Add the TableAdapter again in dataset by right click option See Here 通过右击选择在数据集中再添加TableAdapter的看这里
