Looking for a way to dynamically change field names in PropertyGrid

Question

I've got COM object attached to property grid.

Type typeObj = Type.GetTypeFromProgID(progIdService);
var obj = Activator.CreateInstance(typeObj);
propertyGrid1.SelectedObject = obj;

Now I need some way to translate object fields into my language using some translator. I was trying to use wrapper around object but with COM object I have no PropertyInfo, I have only PropertyDescription so I'm still looking for all the possible variants of doing it.

What you could do is reuse the DynamicTypeDescriptor class described in my answer to this question here on SO: PropertyGrid Browsable not found for entity framework created property, how to find it?

like this:

DynamicTypeDescriptor dtp = new DynamicTypeDescriptor(typeObj);

// get current property definition and remove it
var current = dtp.Properties["ThePropertyToChange"];
dtp.RemoveProperty("ThePropertyToChange");

// add a new one, but change its display name
DynamicTypeDescriptor.DynamicProperty prop = new DynamicTypeDescriptor.DynamicProperty(dtp, current, obj);
prop.SetDisplayName("MyNewPropertyName");
dtp.AddProperty(prop);

propertyGrid1.SelectedObject = dtp.FromComponent(obj);

I think you can use reflection to get the property names, although I haven't tried with COM objects yet. Be sure to include the System.Reflection namespace, then you can use it like that:

var props = myComObject.GetType().GetProperties();
foreach (var prop in props)
{
    MessageBox(prop.Name);
}
