關於VS.Net應用的圖示提取方法

.Net的資原始檔

        VS.Net 支援三種檔案型別的resource：.txt、.resx、.resources。

system.resources 名字空間支援三種資原始檔：

    • txt 檔案，只能有字串資源。因為不能被嵌入到 assembly 中，所以非常容易暴露，被客戶修改。最大缺點是僅支援字串資源，所以不推薦使用。
    • .resx 檔案，由 xml 組成，能加入所有資源，包括二進位制。同樣不能被嵌入到 assembly 中。在 system.resources 名字空間中有專用讀寫的類。vs.net 建立這種檔案然後將其轉成 .resources 檔案並根據設定將其嵌入到 assembly 中。
    • .resources 檔案，pe 格式，能加入所有資源。唯一能被嵌入到 assembly 的檔案，在 system.resources 名字空間中有專用讀寫的類。
  1. 把resx檔案通過vs加入到.net工程中後，編譯完成時，它會被轉化為resources檔案並embed到assembly中。
  2. System.resources.resourceManager負責讀取.net assembly中嵌入的resources檔案中的資源資訊。
  3. 三種檔案型別，必須要轉為resources檔案，才能被resourcemanager讀取（顯然的）。ResGen.exe主要完成此項工作。
  4. C++/CLI, vb.net, c#，大家都可以用resx檔案是自然的。只不過在Vs裡新增resx檔案時，c#工程要支援的更完備些：直接替你封裝好了對resourcemanager的使用。
  5. 推薦工具
    • resgen.exe：sdk 中的工具，專門用來做資原始檔型別之間的轉換。支援 .txt <-> .resx <-> .resources 之間的轉換。
    • resourcer：專門用來建立資原始檔，簡單易用，支援 .resx 和 .resources 檔案格式。
    • .net reflector：用來瀏覽 assembly。如果你不確定一個資原始檔的完整名時能用這個工具在 assembly 中檢視。

ResX資原始檔中圖示的提取

    ResX檔案中，是將所有資源（包括二進位制）都寫入到XML檔案中，每個圖示不再以獨立檔案的形式存在。在程式設計工程中，尤其在學習、分析現有.Net應用程式過程中，需要提取現有應用程式中的圖示。基本思路是利用工具軟體，將應用程式的資原始檔提取出來（具體方法可以進行網上搜尋），生成resx或resources檔案。當生成resources檔案時，可以利用resgen.exe進行格式轉換。

    通過對resx檔案格式分析，開發了針對resx格式檔案的圖示提取工具，本工具的具體程式碼如下：
