缺少using指令或程序集引用？ [英] missing a using directive or an assembly reference?

问题描述

我在项目中包含一个表单（Procedure）（Patient_Management_System<）。

这个表单已经在另一个同名中生成Project（Patient_Management_System）

所以当我运行它时错误是..........

I include a form (Procedure) in project(Patient_Management_System<).
This form already made in another Same name Project(Patient_Management_System)
So When I run It Error is..........

Error   1   The type or namespace name 'hospitalDataSet30' could not be found (are you missing a using directive or an assembly reference?) D:\project_duplicate3\Win_login\PROCEDURE.designer.cs   1200    17  Patient_Management_System

推荐答案

从文档中，找出可以找到缺失符号的程序集，并在项目中引用此程序集。另外，找出您尝试使用的类型的完全限定名称并将其完整写入。 （可选）使用带有完整类型名称的别名添加，或者使用为整个程序集名称添加 。

From documentation, find out in which assembly the missing symbol can be found and reference this assembly in your project. Also, find out a fully-qualified name of the type you are trying to use and write it in full. Optionally, add a using alias with the full type name, or, another option, add using for the whole assembly name.
