Load the assembly:
AssemblyDefinition asm = AssemblyDefinition.ReadAssembly(@"C:\...\Assembly.
dll");
ModuleDefinition mainMod = asm.MainModule;
Find the MethodDefinition for the method you're interested in:
TypeDefinition classContainingYourMethod = mainMod.Types.FirstOrDefault (x
=> x.Name == "ClassName"); // this is LINQ
MethodDefinition yourMethod = classContainingYourMethod.Methods.
FirstOrDefault (x => x.Name == "YourMethodsName"); //if your method is void
ShowTooltip(), just type in "ShowTooltip"
Now parse all Classes (types) in your assembly, parse all their Methods,
parse all their Instructions, parse all their Operands and see if it's
referencing yourMethod.
foreach (TypeDefinition td in mainMod.Types)
foreach (MethodDefinition md in td.Methods)
if (md.HasBody)
foreach (Instruction inst in md.Body.Instructions)
if (inst.Operand == yourMethod)
System.Console.WriteLine ("your method is being
called here");
*> how do i verify the parameters that are passed?*
Parameters are pushed onto the evaluation stack in the instructions that
are preceding the call.
*>when finding it, i'd like to verify it was called correctly.*
Don't understand the question.
