Generate PDB from .NET DLL file?

Question

我需要可以从 DLL 文件（C# .NET 代码）生成 PDB 的东西，有没有免费程序可以做到这一点？

Answer 1

Actually you can do it also with dotPeek from 1.2 version onward.

Right click the assembly in Assembly Explorer, and select "Generate Pdb". It also has the option to generate files for referenced assemblies all at once.

Answer 2

Even you have no sources and code obfuscated, you can create pdb by recompile with ildasm and ilasm:

• decompile assembly by ildasm : ildasm /out=assembly_name.il assembly_name.dll
• complile with ilasm : ilasm assembly_name.il /dll /pdb

Answer 3

PDB contains debug symbols related to DLL, and would normally be built together with the DLL. To enable generating pdb files go to project Properties , Build tab, Advanced... button and select in Debug Info field "pdb-only" or "full":

If you need to debug a thirdparty assembly without sources, then dotPeek and ReSharper will be extremely helpful having an option to generate PDB from DLL. In ReSharper, this can be done through ReSharper > Windows > Assembly Explorer by opening necessary assembly and clicking " Generate Pdb... ":

Answer 4

You can use ILSpy . This is the handy free app for disassembling and generating pdb for managed dll's.

Answer 5

您需要源代码才能生成 PDB。
