在代码的designer.cs部分,我只是简单地对组合框进行数据库驱动(它预览数据很好,这样才有效)但是当我尝试编译时,它会抛出2个独特的错误:
1)错误1“DesktopApplication.DesktopApplication”类型中不存在类型名称“mtdDesktopApplicationDataSet”
2)错误2“DesktopApplication.DesktopApplication”类型中不存在类型名称“mtdDesktopApplicationDataSetTableAdapters”
第一个错误出现在第一行,另一个错误显示在'mtdDesktopApplicationDataSetTableAdapters'所在的位置(4行)
所有相应的文件似乎都在那里,但它们只是没有连接好吗?
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();
((System.ComponentModel.ISupportInitialize)(this.mtdDesktopApplicationDataSet)).BeginInit();
((System.ComponentModel.ISupportInitialize)(this.tblStudyBindingSource)).BeginInit();
((System.ComponentModel.ISupportInitialize)(this.tblDeliveryGroupBindingSource)).BeginInit();
((System.ComponentModel.ISupportInitialize)(this.tblDeliveryBindingSource)).BeginInit();
((System.ComponentModel.ISupportInitialize)(this.tblDeliveryDataSetBindingSource)).BeginInit();

您是否在任何时候移动/重命名了文件/类,和/或更改了项目的默认命名空间?我已经看到所有这些都与上面的效果相似。
重新生成(生成)行:
this.mtdDesktopApplicationDataSet =
new DesktopApplication.mtdDesktopApplicationDataSet();
可能值得避免让字段(this.mtdDesktopApplicationDataSet
)与类型(DesktopApplication.mtdDesktopApplicationDataSet
)命名相同 - 这只会导致潜在的错误。目前尚不清楚(无法重现)这是否是一个因素,但它无济于事......
要表示的字段mtdDesktopApplicationDataSet
是什么?你可以重命名吗?
答案 1 :(得分:2)
我猜你正在遇到名称空间的一些问题。如果此代码隐藏文件驻留在DesktopApplication
命名空间中,并且DesktopApplication
命名空间中也有DesktopApplication
类,您将体验上述内容。
(基本上它正在查看DesktopApplication.DesktopApplication
,而应该查看DesktopApplication
。)
尝试清理命名空间,以便上述情况不正确,或使用global
关键字转义命名空间地狱:
this.mtdDesktopApplicationDataSet = new global::DesktopApplication.mtdDesktopApplicationDataSet();
