Analyzing .Net code

Purpose

The .Net analyzer is intended to analyse dependencies between .Net types. It parses the selected assemblies using Mono.Cecil to determine dependencies between .Net types. The element hierarchy is based on types and namespaces.

Pre requisites

• None

Performing an analysis

• Place the assemblies to be analyzed in a single directory.
• Create an analyzer settings file. This can be done by:
  • Using the example below or
  • Running the analyzer with a not existing settings file. A settings file using default settings will be created.
• Edit the analyzer settings file if required:
  • Update the Input.AssemblyDirectory setting to point to the directory where the assemblies to be analyzed are located.
  • Update the Output.Filename to the name of the product.
  • Update LogLevel if required.
• Run the analyzer from the command line with the analyzer settings filename as argument. The analyzer will:
  • Load each assembly found in the AssemblyDirectory.
  • Look for types in the loaded assemblies and register them.
  • Look for type dependencies in the loaded assemblies and register them. It will look at:
    • Type members, properties, methods and events.
    • Method return types, parameters and variables.
    • Generic types and their parameters.
  • The found types and dependencies are written to the OutputFilename.
• At the end of the analysis the percentage of the relations that could be resolved is shown. This is an indication of the reliability of the dependency model. If the percentage lower than 100% look at the log files to find out the reason.
  • If it is a missing product assembly, add it to the AssemblyDirectory
  • If it is a missing third party or system assembly, add it to the AssemblyDirectory or ignore these relations by adding its namespace to the list of ExternalNames.
• Import the DSI file in the DSM viewer.

Command line usage

Use the following command to run a analysis:

"C:\Program Files\DsmSuite\Analyzers\DotNet\DsmSuite.Analyzer.DotNet.exe" AnalyzerSettings.xml

Settings

The following analyzer settings are defined:

Settings example

An example settings file is shown below (DSM Suite analysis example):
