CSV 轉換利器－ServiceStack.Text

做專案免不了遇到匯出或讀取 CSV 的需求，將物件轉成逗號分隔字串看似小菜一碟，用 C# 串字串也能搞定，但魔鬼在細節裡：字串值如包含逗號就要用雙引號包夾，遇到雙引號要置換成兩個雙引號，如果字串內容有換行符號更是讀取識別時的一大挑戰… 不管是匯出或解析 CSV 都得費不少力氣。最近發現一個處理 CSV 的強大元件－ServiceStack.Text 的 CsvSerializer！ ServiceStack 是一套用於快速打造 SOA 服務的 Framework 工具組（可取代 WCF、WebAPI...

HTML轉PDF - 使用Pechkin套件

剛好跟人討論到HTML轉PDF需求，便對工具進行簡單評估以備不時之需。 網路上比較多人推的是 WkHtmlToPdf ，如果是用.NET開發，已經有人包成NuGet套件，直接搜尋pechkin就可找到，它有兩個版本: Pechkin適用單執行緒，如要非同步執行請選用Pechkin.Synchronized。 安裝NuGet套件後，相關Unmanage DLL也會一併下載並加入專案，不用額外安裝HkHtmlToPdf就可開始寫程式，十分方便。但由於Unmanaged部分為32位元，記得要將專案目標平台切成x86...

小試SmartAssembly .NET混淆器

可輕易反組譯是採用中介語言(.NET, Java)平台的共有特性，也是實務應用的資安隱憂，面對這個問題，最有效的解決方案是 -- 混淆器( Obfuscator )。 混淆器的運作原因，是解析編譯好的DLL或EXE檔，將其轉換成執行結果相同的組件，差別在於私有類別、屬性、方法、欄位、參數名稱都已改到面目全非，難以閱讀理解；更進一步還可以打亂程式碼的排列流程(執行順序不變)、加密程式碼中的字串常數，讓反組譯的程式碼亂如咒語天書，令有意破解者卻步，至少要讓對方追程式追到流涕痛哭。天下沒有破解不了的程式...
