C# dynamically set property When Property is a class?

Question

Hi i have a Number of Properties and My properties like

public XYZ()
{
    xyz = new xyz1();
    xyz2 = new xyz2();
}
public xyz1 xyz1 { get; set; }
public xyz2 xyz2 { get; set; }
}

public class xyz1
{
    public string fName { get; set; }
    public string lnameget; set;}
}
public class xyz2
{
    public string city { get; set; }
    public string state
}

While i am setting my property on runtime i am getting exception object reference set to null.

XYZ model = new XYZ();
PropertyInfo propertyInfo = model.GetType().GetProperty("fName");
propertyInfo.SetValue(model, Convert.ChangeType(item.InnerText, propertyInfo.PropertyType), null);

Please help me

Can you just set `model.xyz1.fName` directly? Why use `PropertyInfo`? — mjwills, Aug 16 '17 at 12:31
Because its happening in run time and i don't know about model on runtime that's why — Vaibhav Srivastava, Aug 16 '17 at 12:35
In that case you will need to get the `xyz1` property of `model` and **then** the `fName` property of `xyz1`. Or use `dynamic`. — mjwills, Aug 16 '17 at 12:55

model has no fName property, but model.xyz1 does.
