【C#|使用Reflector.FileDisassembler反编译DLL】 Reflector.FileDisassembler.dll cs文件的工具下载地址 : http://www.denisbauer.com/Downloads/Reflector.FileDisassembler.zip
1.下载Reflector.FileDisassembler.zip,解压后得到一些文件,其中Reflector.FileDisassembler.dll是已经编译好的,其它是它源码;
2.打开Reflector,在view菜单下的Add-Ins,将Reflector.FileDisassembler.dll添加到里面;
3.open一个dll,exe,或mcl为后缀的文件,当然要支持.net的
4.选择要反编译的dll(会在列表中显示),选择Tools->File Disassembler,在右窗口会出现设置存放源码位置的路径,点击产生就可以了!
但是使用FileDisassembler编译成CS文件会有一个Bug, 就是变量、类和名称空间有时会重命名。
幸好FileDisassembler发布的时候带有源代码,也就省得去Reflect一把了,毕竟机器生成的临时变量名看起来还是很不爽的。修复这个bug很简单,修改了一下CreateFile方法,同时添加了一个GetUniqueFileName方法,源代码如下:
private StreamWriter CreateFile(string directory, string fileName)
{
directory = directory.Replace("<", "_");
directory = directory.Replace(">", "_");
directory = directory.Replace(":", "_");
directory = directory.Replace("|", "_");
directory = directory.Replace("?", "_");
directory = directory.Replace("*", "_");
directory = Path.Combine(this.outputDirectory, directory);
ILanguage language = this.LanguageManager.ActiveLanguage;
string fileExtension = language.FileExtension;
fileName = fileName.Replace("<", "_");
fileName = fileName.Replace(">", "_");
fileName = fileName.Replace(":", "_");
fileName = fileName.Replace("|", "_");
fileName = fileName.Replace("?", "_");
fileName = fileName.Replace("*", "_");
fileName = Path.Combine(directory, fileName);
fileName = Path.ChangeExtension(fileName, fileExtension);
fileName = GetUniqueFileName(fileName);
this.WriteLine(fileName);
directory = fileName.Substring(0, fileName.LastIndexOf('""'));
if (!Directory.Exists(directory))
{
Directory.CreateDirectory(directory);
}StreamWriter writer = new StreamWriter(fileName);
return writer;
}private Hashtable fileNames = new Hashtable();
private string GetUniqueFileName(string fileName)
{
string strExtension = Path.GetExtension(fileName);
fileName = fileName.Replace(strExtension, "");
string _fileName = fileName.ToLower();
bool bFirstRename = true;
while(fileNames.Contains(_fileName))
{
string existFileName = (string)fileNames[_fileName];
string [] efnParts = existFileName.Split(new char[] { '""' });
string [] fnParts = fileName.Split(new char[] { '""' });
for (int i = 0;
i < fnParts.Length;
++i)
{
if (efnParts[i] != fnParts[i])
{
if (bFirstRename)
{
fnParts[i] += '_';
bFirstRename = false;
}
fnParts[i] += 'x';
break;
}
}
fileName = string.Empty;
for (int i = 0;
i < fnParts.Length;
++i)
{
fileName += '""' + fnParts[i];
}
fileName = fileName.Substring(1);
_fileName = fileName.ToLower();
}
fileNames[_fileName] = fileName;
return fileName + strExtension;
}
