Adding Custom Attributes that takes Type as constructor argument

[Murugan]

Hi,

I want to add custom attributes to all the methods of a class that takes "Type" as argument

For example:

Assembly1 (TestApplication) : has all the methods

class SampleItems

  {

  public static void Main()

  {

  SampleItems f= new SampleItems ();

  f.Sample ();

  Console .ReadLine ();

  }

    public void Sample()

    {

      Console.WriteLine("sample");

    }

    public void Sample1()

    {

    Console .WriteLine ("sample1");

    }

  }

Attribute is defined in the assembly2 ((Sample.dll)) and also it has the class to be applied for annotation

 [System.AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, AllowMultiple=true  )]

  public sealed  class SampleClass :Attribute 

  {

  public Annotation InputType

  {

  get;

  set;  

  }

  public SampleClass (Annotation Test)

  {

  if(Test is Annotation )

  {

  InputType =Test ;

  }

  }

  

}

public class Annotation

  {

  public void TestingTers(){

  Console .WriteLine ("This is sample for testing ters");

  }

}

And I am mixing the attribute via the following code in a separate exe

 var sampleDll = AssemblyDefinition.ReadAssembly("SampleDll.dll");

     var targetExe = AssemblyDefinition.ReadAssembly(@"TestApplication.exe");

      

      foreach (var typeDef in sampleDll.Modules)

      {

        foreach (var typeDefname in typeDef.Types)

        {

        if (typeDefname .Name =="SampleClass")

        {

          var sampleClass = sampleDll.MainModule.GetType("SampleDll." + typeDefname.Name);

          var sampleClassCtor = sampleClass.Methods.First(m => m.IsConstructor);

          

          var ctorReference = targetExe.MainModule.Import(sampleClassCtor);

          foreach (var type in targetExe.MainModule.Types)

          {

            foreach (var methodDef in type.Methods)

            {

              var custatt = new CustomAttribute(ctorReference);

           

              custatt.ConstructorArguments.Add(new CustomAttributeArgument( targetExe .MainModule .TypeSystem.String  , sampleDll.MainModule.GetType("SampleDll.Ters").FullName ));

//How to add constructor argument that take a type as input

//Please suggest me

              methodDef.CustomAttributes.Add(custatt);

           

            }

           

            }

        }

      

      }

      }

      

      targetExe.Write(@"TestApplicationupdate.exe");

      Console .ReadLine ();

    }  

So the Final output will be

=====================

[SampleClass(Annotation)]

    public void Sample1()

    {

    Console .WriteLine ("sample1");

    }

looking forward for your reply
