I have different objects like: CallingItem, TransferItem or FlowItem and I have an appropriated String containing the needed property of the object e.g. Message.Start.MsgNumber or Data.Name

Examples of my objects with property:

TransferItem.Message.Start.MsgNumber = 5;
CallingItem.Data.Name = "Mike"

Method call:

GetProperty(TransferItem, "Message.Start.MsgNumber");
GetProperty(CallingItem, "Data.Name");

Method GetProperty:

public void GetProperty(object myObject, string propertyString)
{
    Type t = myObject.GetType();

    PropertyInfo pinfo = t.GetProperty(propertyString);

    if (pinfo == null)
        return;

    object value = pinfo.GetValue(null, null);
}

But pinfo is always null. How can I get the property value of my object?

Why do you work with strings at all? – Rob Sep 04 '17 at 07:01
`GetProperty` does not support nesting properties like "Foo.Bar". – DerApe Sep 04 '17 at 07:01
You need some recursive method that returns just a single part of your path instead of the entire structure. – MakePeaceGreatAgain Sep 04 '17 at 07:05
