情境:需要從T_User表中返回指字條件的某條記錄的某一個欄位在Linq中有二種理論上都行得通的寫法,見下面的代碼:CodeCode highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->using (dbUserDataContext db = new dbUserDataContext(Website.ConnStrdbUser)) {
由於工作的關係,常常需要擷取某段字串的編碼資訊,防止亂碼出現。在網上找了一下,有下面幾個庫1.C#https://code.google.com/p/ude/ 探測庫 Ude is a C# port of Mozilla Universal Charset Detector. The original source code is available at:
藉助老外寫的一個擴充運算式的類,可以把上篇中的代碼寫得更優雅這是PredicateBuilder的源檔案 public static class PredicateBuilder ...{ public static Expression<Func<T, bool>> True<T> () ...{ return f => true; } public static Expression<Func<T, bool
在手寫sql的年代,如果想從sqlserver資料庫隨機取幾條資料,可以利用order by NewId()輕鬆實現,要實現多表查詢也可以用select * from A,B Where A.ID=B.ID做到,但這些功能到了linq to sql中如何?呢?關鍵點:1.隨機排序問題:可以用 Select(d=> new {NewId=new Guid()}).OrderBy(d=>d.NewId)達到order by NewId()的效果2.多表查詢 from a in
