Visual C#2008速成版 [英] Visual C# 2008 Express

问题描述

我在Visual Studio中遇到一个基本问题.

我正在使用Visual C#2008 Express Edition
我有.net framework 3.5


我无权访问HashSet< t>课.

它位于System.Cores中包含的System.Collections.Generic中.

我在项目中包含对System.Core的引用，并且在我的课程中包含了Systems.Collections.Generic.

我拥有所有System.Collections.Generic类，除了HashSet.

I''m having a fairly basic problem with Visual Studio.

I''m using Visual C# 2008 Express Edition
I have .net framework 3.5


I have no access to HashSet<t> class.

It''s in System.Collections.Generic, which is included in System.Core.

I have included a reference to System.Core in my project, and I have included Systems.Collections.Generic in my class.

I have all of the System.Collections.Generic classes EXCEPT HashSet.

Anyone have any possible problems?

推荐答案

我不使用Express，但是它是在.NET 3.5中引入的，因此您应该拥有它. 试试这个:
1)作为解决方案的一部分，创建一个新项目-为简单起见，使其成为一个控制台应用程序，并确保它是.NET Framework 3.5版(全部位于添加项目对话框屏幕上)
2)在您的Main方法中，开始新行，然后键入Hash.

智能感知会列出HashSet<>吗?

按以下方式完成该行:

I don\''t use Express, but it was introduced at .NET 3.5 so you should have it.
Try this:
1) Create a new project as part of your solution - make it a Console App, for simplicity, and ensure it is .NET framework version 3.5 (this is all on the add project dialog screen)
2) In your Main method, start a new line, and type Hash.

Does intellisense list HashSet<>?

Complete the line as:

HashSet<string> hs = new HashSet<string>();

HashSet的语法颜色会更改吗?
如果不是，请右键单击单词HashSet-您是否有一个选项"Resolve \"?如果是这样，各种选项会怎样?
