CIL-Reader for Methods(e.g. dynamic) and Delegates

Common Intermediate Language reader, analyzer and visualizer tool.
Allows you to access CIL-instructions of .Net method's bodies.

Core Library (ILReader.Core)

Provides a way to read and interprete CIL-bytes of methods and delegates bodies.

Usage:

var method = typeof(...).GetMethod(...);
// or
var method = delegate.Method;
// or
var method = (DynamicMethod)(/* create or get method */);

Get Reader:

IILReader GetReader(MethodBase method) {
    IILReaderConfiguration cfg = Configuration.Resolve(method);
    return reader = cfg.GetReader(method);
}

Iterate instructions one-by-one:

foreach(IInstruction instruction in reader) {
    var opCode = instruction.OpCode
    object operand = instruction.Operand;
    int ILOffset = instruction.Offset;
    // ...
}

Visualizer Library (ILReader.Visualizer)

Debugger Visualizer for Visual Studio. Provides a way to view CIL-bytes of methods and delegates bodies.

Usage:

Func<...> someFunc = ...; // Just use it while debugging

Analyzer Library (ILReader.Analyzer)

Provides a way to detect typical patterns in CIL-bytes.

Usage:

class Bar {
    public void Stub() {
        throw new NotImplementedException("Stub");
    }
}

Check whether or not the method's body match pattern:

var method = typeof(Bar).GetMethod("Stub");
var reader = GetReader(method);
// use default pattern or create you own
var pattern = Analyzer.NotImplemented.Instance;
if (pattern.Match(reader)) {
    // do something
}

Real usage

• MSIL-level boxing detector tool for .Net
• Simple static analysis(SA) tool to analyze .Net assemblies at the IL-code level with visual client
