How to resolve the exclamation mark appearing during ILSpy decompilation?

When using ILSpy to decompile a program, if an exclamation point appears, it usually means that ILSpy is unable to resolve or restore certain code. This could be due to the following reasons:

1. Code is obfuscated: Some developers use code obfuscation tools to conceal and protect their code. These obfuscation tools alter the structure and naming of the program, making it difficult to decompile. In this scenario, it is hard to fully recover the original code.
2. Missing dependencies: If a decompiled program references external libraries or dependencies that are not available during decompilation, ILSpy may not be able to resolve them and display an exclamation mark.
3. Decompiler error: Sometimes, ILSpy itself may have some errors or limitations that prevent it from properly resolving certain code. In this case, you can try using other decompilers or tools to handle the program.

To resolve this issue, you can try the following methods:

1. Update ILSpy to the latest version to ensure that you are using the most up-to-date version. New versions typically fix some errors and improve the program’s parsing capabilities.
2. Try different decompilation tools: In addition to ILSpy, there are many other decompilation tools available. Try using a different tool to process your program and see if it can correctly parse the code.
3. Manual repair: If you have a good understanding of programming languages and code structure, you can manually fix some unresolved code. This may involve looking at the original code of the compiled program and then manually modifying the generated code from ILSpy.

Please be aware that decompiling software may violate the software’s license agreement and legal regulations. Make sure to use decompilation tools in compliance with applicable laws and licensing regulations.
