I am trying to find all the types that a given type is dependent on, including interfaces, abstract classes, enums, structs, etc. I want to load up an assembly, and print out a list of all the types defined within it, and their dependencies.
So far I have been able to find all the the external types a CLR assembly depends on using Mono.Cecil, e.g.
using System;
using Mono.Cecil;
using System.IO;
FileInfo f = new FileInfo("SomeAssembly.dll");
AssemblyDefinition assemDef = AssemblyFactory.GetAssembly (f.FullName);
List<TypeReference> trList = new List<TypeReference>();
foreach(TypeReference tr in assemblyDef.MainModule.TypeReferences){
trList.Add(tr.FullName);
}
This list can also be obtained using the mono disasembler, eg "monodis SomeAssembly.dll --typeref", but this list doesnt seem to include primitives, eg System.Void, System.Int32, etc
I need to treat each type individually, and get all types that a given type depends on, even if the types are defined in the same assembly. Is there any way to do this using Mono.Cecil, or any other project?
I know it can be done by loading the assembly, then iterating over each defined type, then loading the IL of the type and scanning it for references, but I am sure that there is a better way. Ideally it will also work with anonymous inner classes.
It should also work if multiple modules are defined in the same assembly.
AJ, I had the same issue where I needed to traverse the Types in an assembly and I settled on using Mono.Cecil. The way I was able to walk through each Class and if a Property in a Class was not another Class instead of a CLR type was through a recursive function.
private void BuildTree(ModuleDefinition tempModuleDef , TypeDefinition tempTypeDef, TreeNode rootNode = null)
{
AssemblyTypeList.Add(tempTypeDef);
TreeNode tvTop = new TreeNode(tempTypeDef.Name);
// list all properties
foreach (PropertyDefinition tempPropertyDef in tempTypeDef.Properties)
{
//Check if the Property Type is actually a POCO in the same Assembly
if (tempModuleDef.Types.Any(q => q.FullName == tempPropertyDef.PropertyType.FullName))
{
TypeDefinition theType = tempModuleDef.Types.Where( q => q.FullName == tempPropertyDef.PropertyType.FullName)
.FirstOrDefault();
//Recursive Call
BuildTree(tempModuleDef, theType, tvTop);
}
TreeNode tvProperty = new TreeNode(tempPropertyDef.Name);
tvTop.Nodes.Add(tvProperty);
}
if (rootNode == null)
tvObjects.Nodes.Add(tvTop);
else
rootNode.Nodes.Add(tvTop);
}
This Function is called by my main Function the gist of which is
public void Main()
{
AssemblyDefinition assemblyDef = AssemblyDefinition.ReadAssembly(dllname);
//Populate Tree
foreach (ModuleDefinition tempModuleDef in assemblyDef.Modules)
{
foreach (TypeDefinition tempTypeDef in tempModuleDef.Types)
{
BuildTree(tempModuleDef ,tempTypeDef, null);
}
}
}
