mono.cecil

问题 How can I inject a custom method into a .net assembly using mono.cecil, and then call it in the entrypoint? I like to do this to implement security methods after the binary is built. 回答1: To inject method you need to get the type you want to add it the method and then add a MethoDefinition . var mainModule = ModuleDefinition.ReadModule(assemblyPath); var type = module.Types.Single(t => t.Name == "TypeYouWant"); var newMethodDef= new MethodDefinition("Name", MethodAttributes.Public, mainModule

问题 When I read an assembly and rename a field that's contained inside a generic type, and then write the assembly, all references to this field inside the methods become unresolved tokens. I know that the same also happens to method references if I rename them. // This is a generic class. TypeDefinition type = GetSomeGenericType(); // This field is referenced from a method in this type. type.Fields[0].Name = "_anotherName"; assemblyDefinition.Write(...); The resulting assembly won't work. Is

问题 I want to create a custom msbuild task that applies IL rwriting to my output assembly. At the moment i am already using PostSharp and now try to extend the rewriting capabilities. For some special cases i use Mono.Cecil to rewrite some proxy types into the assembly. This works fine right now. But now i want to intercept the build process between the actual build and the PostSharp transformation in order to generate aspects on my proxy types that get implemented by PostSharp in the next step.

问题 How can I remove all DebuggerHiddenAttribute from an assembly only if the compiler generated this attribute? I'm trying this code, but it doesn't work. ModuleDefinition module = ...; MethodDefinition targetMethod = ...; MethodReference attributeConstructor = module.Import( typeof(DebuggerHiddenAttribute).GetConstructor(Type.EmptyTypes)); targetMethod.CustomAttributes.Remove(new CustomAttribute(attributeConstructor)); module.Write(...); Thanks in advance. 回答1: This is not really possible. The

问题 I am trying to use Mono Cecil to manipulate a DLL. What I want to do is to set the base type of some classes to System.MarshalByRefObject from mscorlib.dll . I am using the following code. var assembly = AssemblyDefinition.ReadAssembly(inputtarget); var types = assembly.MainModule.Types; var myTypesToChange = types.Where(...).Select(t => t); var baseType = AssemblyDefinition.ReadAssembly(@"C:\Windows\Microsoft.NET\Framework64\v4.0.30319\mscorlib.dll").MainModule.Types.Where(t => t.Name

问题 I require the ability to preprocess a number of C# files as a prebuild step for a project, detect the start of methods, and insert generated code at the start of the method, before any existing code. I am, however, having a problem detecting the opening of a method. I initially tried a regular expression to match, but ended up with far too many false positives. I would use reflection, but the MethodInfo class does not reference the point in the original source. EDIT : What I am really trying

问题 How can I get a MethodReference to a base class' method by name? I've tried type.BaseType.Resolve().Methods; and if I add the dll containing the base class to the assemblyresolver it returns the methods. But if I add a call using MSILWorker.Create(OpCodes.Call, baseMethod); (where baseMethod was found by foreaching Methods from the resolved TypeDefinition) the resulting IL is unreadable, even Reflector freezes and quits. Now some IL: if calling private method on type: call instance void

问题 The code below allows me to change methods body and save back the assembly. // Recreate PDB var assemblyResolver = new DefaultAssemblyResolver(); var assemblyLocation = Path.GetDirectoryName(pathBin); assemblyResolver.AddSearchDirectory(assemblyLocation); /*if (!string.IsNullOrEmpty(HintPath)) { assemblyResolver.AddSearchDirectory(HintPath); }*/ var silverlightAssemblyPath = Environment.ExpandEnvironmentVariables(@"C:\Windows\Microsoft.NET\Framework64\v4.0.30319\"); assemblyResolver

问题 I have a version of Mono.Cecil which does not have the AssemblyFactory class. Probably it is the 0.9 version of the Cecil class. Is there a way out? 回答1: Just use AssemblyDefinition.Write(fileName) 来源： https://stackoverflow.com/questions/13682491/how-to-save-a-changed-assembly-using-mono-cecil

问题 I use Mono.Cecil to create a new custom attribute type and then add it to an existing type. To demonstrate it, I have a pre-existing DLL called "Sample" with type that is called "SampleType". I want to use Mono.Cecil to weave in a new type in "Sample" called "NewAttribute" and then add this attribute to "SampleType". The code looks like this: (not exactly but its good enough for example) static void AddCustomeAttribute() { var module = ModuleDefinition.ReadModule(AssemblyName); var attrType =
