  • 关于VS.Net应用的图标提取方法

    .Net的资源文件

            VS.Net 支持三种文件类型的resource：.txt、.resx、.resources。

    system.resources 名字空间支持三种资源文件：

      • txt 文件，只能有字符串资源。因为不能被嵌入到 assembly 中，所以非常容易暴露，被客户修改。最大缺点是仅支持字符串资源，所以不推荐使用。
      • .resx 文件，由 xml 组成，能加入所有资源，包括二进制。同样不能被嵌入到 assembly 中。在 system.resources 名字空间中有专用读写的类。vs.net 创建这种文件然后将其转成 .resources 文件并根据设置将其嵌入到 assembly 中。
      • .resources 文件，pe 格式，能加入所有资源。唯一能被嵌入到 assembly 的文件，在 system.resources 名字空间中有专用读写的类。
    1. 把resx文件通过vs加入到.net工程中后，编译完成时，它会被转化为resources文件并embed到assembly中。
    2. System.resources.resourceManager负责读取.net assembly中嵌入的resources文件中的资源信息。
    3. 三种文件类型，必须要转为resources文件，才能被resourcemanager读取（显然的）。ResGen.exe主要完成此项工作。
    4. C++/CLI, vb.net, c#，大家都可以用resx文件是自然的。只不过在Vs里添加resx文件时，c#工程要支持的更完备些：直接替你封装好了对resourcemanager的使用。
    5. 推荐工具
      • resgen.exe：sdk 中的工具，专门用来做资源文件类型之间的转换。支持 .txt <-> .resx <-> .resources 之间的转换。
      • resourcer：专门用来创建资源文件，简单易用，支持 .resx 和 .resources 文件格式。
      • .net reflector：用来浏览 assembly。如果你不确定一个资源文件的完整名时能用这个工具在 assembly 中查看。

    ResX资源文件中图标的提取

        ResX文件中，是将所有资源（包括二进制）都写入到XML文件中，每个图标不再以独立文件的形式存在。在编程工程中，尤其在学习、分析现有.Net应用程序过程中，需要提取现有应用程序中的图标。基本思路是利用工具软件，将应用程序的资源文件提取出来（具体方法可以进行网上搜索），生成resx或resources文件。当生成resources文件时，可以利用resgen.exe进行格式转换。

        通过对resx文件格式分析，开发了针对resx格式文件的图标提取工具，本工具的具体代码如下：

       程序运行后，通过File-Open加载resx资源文件，图标将列在ListView控件中，界面如下：

        通过File——Export...选择目标目录，将图标导出到指定目录。

    另外，针对System.Drawing.Icon、ImageList的ImageStream也可以进行相应处理，代码如下：

 4                         ImageList1.Images.Add(image)
 5                         ListView1.Items.Add(New ListViewItem(n.ToString(), n))
 6                         n += 1
 7                     End If
 8                 End If
 9                 If Operators.CompareString(d.Key.ToString(), "ImageList1.ImageStream", False) = 0 Then
10                     imgList.ImageStream = CType(resxSet.GetObject(d.Key.ToString(), True), System.Windows.Forms.ImageListStreamer)
11                     For i As Integer = 0 To imgList.Images.Count - 1
12                         ImageList1.Images.Add(imgList.Images(i))
13                         ListView1.Items.Add(New ListViewItem(n.ToString(), n))
14                         n += 1
15                     Next
16                 End If
    View Code

    其中，可以输入ImageList控件名称，来选择具体解析对象。
