Assuming we have a method defined as below.

public class SomeClass
{
    [My("beautifulName")]
    public void DoSomeThing()
    {
         // whatever.
    }
}

public MyAttribute : Attribute
{
    public string Name { get; init; }
    public MyAttribute(string name) => Name = name;
}

Now we got a memory dump of this application, we can use ClrMD to find the SomeClass type easily, then we can easily find the DoSomeThing ClrMethod. Now, how can I find the corresponding MyAttribute instance and get the beautifulName value?

what memory tool are you using? you'll have to read the il metadata to know what attributes are applied – Daniel A. White Jan 22 '22 at 17:11
@DanielA.White: WinDbg, SOS or ClrMD as the tags say. – Thomas Weller Jan 22 '22 at 17:22
Why would you want to do this? All instances of that class have the same value, so any `SomeClass` object will have the value `"beautifulName"`. – Thomas Weller Jan 22 '22 at 17:25
@ThomasWeller, because I don't have the code, only have the dump, so I need a way to detect the `beautifulName` in the dump itself. – Ruikuan Jan 24 '22 at 01:17
Write the DLL to disk and open it in dotPeek / dnSpy? – Thomas Weller Jan 24 '22 at 07:23
Actually I don't know how to "write the dll to disk" from the memory dump. And I want to do this task automatically... – Ruikuan Jan 25 '22 at 03:51
