How do you extract classes' source code from a dll file?

问题

Is there any software to do this? I didn't find any useful information on the internet so I am asking here.

回答1:

You cannot get the exact code, but you can get a decompiled version of it.

The most popular (and best) tool is Reflector, but there are also other .Net decompilers (such as Dis#). You can also decompile the IL using ILDASM, which comes bundled with the .Net Framework SDK Tools.

回答2:

Only managed Languages like c# and Java can be decompiled completely.You can view complete source code. For Win32 dll you cannot get source code.

For CSharp dll Use DotPeek becoz it free and works same as ReDgate .Net Compiler

Have fun.

回答3:

Use .NET reflector.

回答4:

Use dotPeek

Select the .dll to decompile

That's it

回答5:

You can use Reflector and also use Add-In FileGenerator to extract source code into a project.

回答6:

Use Refractor. Download from here.

1. Open the software after installing.
2. Press Ctrl + O and select your DLL File.
3. Dll will be shown in left pane.
4. Right click on Dll and select Export Source Code.
5. Select the folder in which you want to export your files
6. Wait for a while it may take 2-3 minutes

回答7:

If you want to know only some basics inside the dll assembly e.g. Classes, method etc.,to load them dyanamically

you can make use of IL Disassembler tool provided by Microsoft.

Generally located at: "C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin"

回答8:

I used Refractor to recover my script/code from dll file.

回答9:

You can use dotPeek The only thing I have to say is that when using it, right-click on the class to select Decompiled Source instead of double-clicking, otherwise dotpeek will only display the contents of the local cs file, not the decompiled content. Option instance

 var destinationfilename = "";
        if (System.IO.File.Exists("nameoffile.dll"))
        {
          destinationfilename = (@helperRoot + System.IO.Path.GetFileName(medRuleBook.Schemapath)).ToLower();
          if (System.IO.File.Exists(destinationfilename)) System.IO.File.Delete(destinationfilename);
          System.IO.File.Copy(@'nameoffile.dll", @destinationfilename);
        }
        // use dll-> XSD
        var returnVal =
          await DoProcess(
            @helperRoot + "xsd.exe", "\"" + @destinationfilename + "\"");
        destinationfilename = destinationfilename.Replace(".dll", ".xsd");
        if (System.IO.File.Exists(@destinationfilename))
        {
          // now use XSD
          returnVal =
            await DoProcess(
              @helperRoot + "xsd.exe", "/c /namespace:RuleBook /language:CS " + "\"" + @destinationfilename + "\"");
          if (System.IO.File.Exists(@destinationfilename.Replace(".xsd", ".cs")))
          {
            var getXSD = System.IO.File.ReadAllText(@destinationfilename.Replace(".xsd", ".cs"));

          }
        }
