peek_il

Return ilasm-style IL for a single method in a referenced closed-source assembly. Input must be a fully-qualified method name with parameter types.

Parameters​

ParameterTypeRequiredDescription
methodSymbolstring✓Fully-qualified method name with parameter types, e.g. 'Newtonsoft.Json.JsonConvert.SerializeObject(object)'

Examples​

Disassemble a regular method:

Use peek_il for JsonConvert.DeserializeObject

Disassemble a constructor (use .ctor):

Use peek_il for SqlOrderRepository..ctor

When to use​

Use peek_il when you need to understand what a closed-source method actually does — for example, to verify thread-safety, understand exception handling, or check whether a method has side effects not apparent from its signature.

Notes​

  • Output is MSIL, not C#. For C# decompilation, use a tool like ILSpy or dnSpy directly.
  • The assembly must be referenced by at least one project in the active solution.
  • The IL cache is invalidated automatically when the DLL changes on disk.
