實際發生的問題,因爲我改變項目名稱StudentSys到StudentMgmSystem
變了樣下面的問題解決
<EntityTypeShape EntityType="StudentMgmSystemModel.Login" Width="1.5" PointX="0.75" PointY="0.75" IsExpanded="true" />
<EntityTypeShape EntityType="StudentMgmSystemModel.HostelDetail" Width="1.5" PointX="5.375" PointY="0.75" />
<EntityTypeShape EntityType="StudentMgmSystemModel.PersonalInfo" Width="1.5" PointX="2.75" PointY="0.875" />
<EntityTypeShape EntityType="StudentSysModel.Login" Width="1.5" PointX="0.75" PointY="0.75" IsExpanded="true" />
<EntityTypeShape EntityType="StudentSysModel.HostelDetail" Width="1.5" PointX="5.375" PointY="0.75" />
<EntityTypeShape EntityType="StudentSysModel.PersonalInfo" Width="1.5" PointX="2.75" PointY="0.875" />
好像您將兩個前級後名稱爲'PersonalInfo' – CodeNotFound
不,我檢查沒有重複的類 – Pravin
