如何从exe文件提取相同.ico文件是用于创建此exe的人吗？ [英] How to extract from exe file the same .ico file as the one used to create this exe?

问题描述

我试图做出某种SFX的：使程序产生围绕另一个wrapped.exe一个wrapping.exe

I'm trying to make some kind of SFX: make a program generating a wrapping.exe around another wrapped.exe.

Wrapping.exe嵌入wrapped.exe作为资源和在被执行时，wrapped.exe被保存到临时文件夹中，与特定的命令行参数执行，并且然后被删除。 wrapped.exe并不总是一个.net计划，我没有为它的源代码。

Wrapping.exe embed wrapped.exe as resource and, when executed, wrapped.exe is saved into temporary folder, executed with specific command line arguments and then deleted. wrapped.exe is not always a .Net program and I don't have source code for it.

wrapping.exe应在.net 3.5做是为了上可用Windows 7的SP1和上没有任何事先的.NET安装。

wrapping.exe should be done in .Net 3.5 to be usable on Windows 7 SP1 and upper without any prior .Net installation.

Wrapping.exe是：在.NET 4.6罗斯琳使用C＃程序产生的。

Wrapping.exe is generated with a C# program using Roselyn in .Net 4.6.

我需要wrapping.exe进行可视化像探险家wrapped.exe。我做了与硬编码.ico文件测试成功。代码看起来像这样（简体）：

I need wrapping.exe to be visualized like wrapped.exe by explorer. I've made a successful test with an hardcoded .ico file. Code look like this (simplified):

var compilation = CSharpCompilation.Create(...);
var resourceDescription = new ResourceDescription( resourceName: "SFX.resourceName",
                                                   dataProvider: () => File.OpenRead("wrapped.exe"),
                                                   isPublic:     false);

using (var iconStream = File.OpenRead(@"wrapped.ico"))
using (var peStream = File.Create("wrapping.exe"))
using (var pdbStream = File.Create("wrapping.pdb"))
using (var win32resStream = compilation.CreateDefaultWin32Resources(
                                                              versionResource:  true,
                                                              noManifest:       false,
                                                              manifestContents: null,
                                                              iconInIcoFormat:  iconStream))
{
    var emitResult = compilation.Emit( peStream:          peStream,
                                       pdbStream:         pdbStream,
                                       manifestResources: new[] { resourceDescription },
                                       win32Resources:    win32resStream,
                                       options:           new EmitOptions(subsystemVersion: SubsystemVersion.Windows7));
  return emitResult;
}

现在我尝试从wrapped.exe得iconStream。我试图取代：

Now I try to get iconStream from "wrapped.exe". I've tried to replace:

using (var iconStream = File.OpenRead(@"wrapped.ico"))

与

var iconStream = new MemoryStream();
Icon icon = Icon.ExtractAssociatedIcon("wrapped.exe");
icon.Save(iconStream);
iconStream.Seek(0, SeekOrigin.Begin);

但我只得到了32 * 32的图标。

but I only get a 32*32 icon.

如何准确提取同一.ico文件（包括所有的格式，例如具有16×16 32位的BMP，32 * 32 32位的BMP，48 * 48 32位的BMP，64 * 64 32位的BMP和256 * 256 32位PNG）是用于创建wrapped.exe'的人？

How to extract exactly the same .ico file (including all formats, for example with 16*16 32 bits BMP, 32*32 32 bits BMP, 48*48 32 bits BMP, 64*64 32 bits BMP and 256*256 32 bits PNG) as the one used to create 'wrapped.exe'?

推荐答案

这是使用非常方便<一个HREF =htt​​p://www.codeproject.com/Articles/16178/IconLib-Icons-Unfolded-MultiIcon-and-Windows-Vista相对=nofollow> IconLib 。响应已在的这个问题：THX到 @Plutonix

This is very easy using IconLib. The response was already in this question: Thx to @Plutonix!

使用下面的辅助功能（当然，提取图标文件名不会被硬编码）：

With following helper function (of course, extraction icon file name will not be hardcoded):

static Stream GetIconStream_ExtractIconUsingIconLib(string fileToExecute)
{
    var multiIcon = new MultiIcon();
    multiIcon.Load(fileToExecute);

    var extractedicoFileName = @"c:\temp\icon.ico";
    multiIcon.Save(extractedicoFileName, MultiIconFormat.ICO);

    return File.OpenRead(extractedicoFileName);
}

我们只需要替换：

File.OpenRead(@"wrapped.ico")

与

GetIconStream_ExtractIconUsingIconLib("wrapped.exe")

这为我们提供了完整的解决方案：

This gives us full solution:

var compilation = CSharpCompilation.Create(...);
var resourceDescription = new ResourceDescription( resourceName: "SFX.resourceName",
                                                   dataProvider: () => File.OpenRead("wrapped.exe"),
                                                   isPublic:     false);

using (var iconStream = GetIconStream_ExtractIconUsingIconLib("wrapped.exe"))
using (var peStream = File.Create("wrapping.exe"))
using (var pdbStream = File.Create("wrapping.pdb"))
using (var win32resStream = compilation.CreateDefaultWin32Resources(
                                                              versionResource:  true,
                                                              noManifest:       false,
                                                              manifestContents: null,
                                                              iconInIcoFormat:  iconStream))
{
    var emitResult = compilation.Emit( peStream:          peStream,
                                       pdbStream:         pdbStream,
                                       manifestResources: new[] { resourceDescription },
                                       win32Resources:    win32resStream,
                                       options:           new EmitOptions(subsystemVersion: SubsystemVersion.Windows7));
  return emitResult;
}
