VS2005,C#-数据绑定组合框-默认情况下,代码隐藏会给我错误

在代码的designer.cs部分中,我只是简单地将组合框设置为数据库驱动(它可以很好地预览数据,这样就可以了),但是当我尝试编译时,它会抛出两个唯一的错误:

1) 错误1类型“DesktopApplication.DesktopApplication”中不存在类型名称“mtdDesktopApplicationDataSet”

2) 错误2类型“DesktopApplication.DesktopApplication”中不存在类型名称“mtdDesktopApplicationDataSetTableAdapters”

第一个错误在第一行,另一个错误显示在“mtdDesktopApplicationDataSetTableAdapters”所在的位置(4行)

所有适当的文件似乎都在那里,但它们只是没有正确连接?

this.mtdDesktopApplicationDataSet = new DesktopApplication.mtdDesktopApplicationDataSet();
this.tblStudyBindingSource = new System.Windows.Forms.BindingSource(this.components);
this.tblStudyTableAdapter = new DesktopApplication.mtdDesktopApplicationDataSetTableAdapters.tblStudyTableAdapter();
this.tblDeliveryGroupBindingSource = new System.Windows.Forms.BindingSource(this.components);
this.tblDeliveryGroupTableAdapter = new DesktopApplication.mtdDesktopApplicationDataSetTableAdapters.tblDeliveryGroupTableAdapter();
this.tblDeliveryBindingSource = new System.Windows.Forms.BindingSource(this.components);
this.tblDeliveryTableAdapter = new DesktopApplication.mtdDesktopApplicationDataSetTableAdapters.tblDeliveryTableAdapter();
this.tblDeliveryDataSetBindingSource = new System.Windows.Forms.BindingSource(this.components);
this.tblDeliveryDataSetTableAdapter = new DesktopApplication.mtdDesktopApplicationDataSetTableAdapters.tblDeliveryDataSetTableAdapter();
