Question

I need to cast an object to a System.Type object.

I’ve read that C# is statically typed so that would not be possible.

Is this true?

If yes, how can I accomplish this?

Assembly myDll = Assembly.LoadFrom(dllData.Path);
Type manyAttribute = myDll.GetExportedTypes().FirstOrDefault(...);
Type multiplicityAttribute = myDll.GetExportedTypes().FirstOrDefault(..);

//Here is the problem
propertiesOnOtherFile = propertiesOnOtherFile.Where(t =>
    t.GetCustomAttributes(false).Any(ca => 
    !string.IsNullOrEmpty(((multiplicityAttribute)ca).PropertyName))); 

This is the line:

((multiplicityAttribute)ca).PropertyName)

Is there any other way to do this?

EDIT:

Due to many questions, this is my scope:

public class PocoClass
{
    [ManyAttribute]
    public ObjectX MyProp;
}

ManyAttribute declaration
{
    public string PropertyName;
}

ManyAttribute is in the dynamicly loaded DLL.
Then, as in my example above, I need to cast the customAttribute (ManyAttribute) to ManyAttribute so I check PropertyName’s value.

I still don’t get this… but this should work.

        IEnumerable<Type> propertiesOnOtherFile = new List<Type>(); //from somewhere?

        //Here is the problem
        propertiesOnOtherFile = propertiesOnOtherFile.Where(t =>
            t.GetCustomAttributes(false).Any<dynamic>(ca => 
            !string.IsNullOrEmpty(ca.PropertyName)));
