准备材料:
- Visual Studio 2008 (Beta2 或更高版本)
- 一些需要搜索的字符串
类别: LINQ-To-Objects, LINQ and string, LINQ and WinForms
制作方法:
- 打开Visual Studio 2008,点击菜单“文件/新建项目”,找到并双击 ”Windows 窗体应用程序” 图标
- 拖放一个Listbox 到窗体上,调整它的高度,然后拖放一个按钮到窗体上
- 双击这个按钮,并将下面的代码添加到按钮的事件处理函数中:
Dim text = "Good morning everyone. I'd like to welcome " & _
"you to today's presentation on LINQ. My " & _
"name is Kit George and I'm a Program Manager " & _
"for Microsoft, on the Visual Basic team. You " & _
"might be wondering where my accent is from? " & _
"Well, I hail from a small country called New " & _
"Zealand but it sure is great to be here in " & _
"Atlanta today!"
Dim capitalWords = _
From word In text.Split( _
New Char() {",", ".", "!", " "}, _
StringSplitOptions.RemoveEmptyEntries) _
Where word(0) = Char.ToUpper(word(0)) _
Order By word.Length, word
ListBox1.Items.AddRange(capitalWords.ToArray())
- 修改你要搜索的字符串。如果字符串保存在一个文件中, 可以使用 My.Computer.FileSystem.ReadAllText 获取并保存到字符串变量中。
