代码说明:

C# 创建泛型字典,为泛型字典添加3个元素,按键值对泛型字典进行排序操作。   Dictionary users = new Dictionary();//创建泛型字典   users.Add(3, new UserInfo(1, "滕*敏", "01"));//为泛型字典添加3个元素   users.Add(2, new UserInfo(2, "滕*娜", "02"));   users.Add(1, new UserInfo(3, "X家兴", "03"));   //按键值对泛型字典进行排序操作   var query = from item in users    where item.Value.UserName.CompareTo("滕*") > 0//用户名大于"滕立"    orderby item.Key    select item;   label1.Text = "显示查询结果: ";   foreach (var item in query)//显示查询结果

  • 包括枚举功能的VB窗口管理器源代码
    一款涉及到枚举功能的VB窗口管理器源码,程序作者:倒霉蛋儿。所包括的功能操作:枚举窗口、结束进程、清空列表等。   枚举进程采用For循环枚举的方法,可以枚举到所有窗口和控件,但是速度很慢!您可以按Ctrl键+S键停止枚举。源代码中涉及到许多的窗口操作小技巧,是VB学习者挺不错的范例源码。

  • Emdros is a text database middleware
    Emdros is a text database middleware-layer aimed at storage and retrieval of "text plus information about that text." This information could be linguistic analyses or other annotations. Emdros provides an abstraction of text that makes it well suited to storing /syntactic analyses/ of text, but other linguistic information is supported as well. Emdros comes with a query-language, MQL, that enables powerful queries. Emdros acts as a middleware-layer between a client (not provided) and a database back-end. Currently, PostgreSQL, MySQL, and SQLite (2 and 3) are supported, but other back-ends can easily be added.-Emdros is a text database middleware-layer aimed at storage and retrieval of "text plus information about that text."
