Question

I am trying to change properties of controls using strings for control name, control AssemblyQualifiedName, Property name and property value

---

What I have tried:

public void ChangeIt(string ctrlName, string typ,
                     string prop, string value)
{
    Type t = Type.GetType(typ);
    dynamic obj = Convert.ChangeType(App.Current.MainWindow.FindName(ctrlName), t);
    // Now how to
    // obj.Prop=value;
}

ChangeIt("Label1",
        "System.Windows.Controls.Label, PresentationFramework, Version=4.0.0.0,Culture=neutral,PublicKeyToken=31bf3856ad364e35",
        "Content", "Hellow World!");

Thank you

You don’t really need the type at all, and you don’t need to use dynamic.

public void ChangeIt(string ctrlName, string typ, string prop, string value) {
     object obj = App.Current.MainWindow.FindName(ctrlName);
     obj.GetType().GetProperty(prop).SetValue(obj, value);
}
