在 VB6 中使用 bang(!) 运算符在 C# dll 中返回 object

Question

With ADO there is the recordset object which allows you to iterate through rows showing getting values from columns in this way...

Do While Not someRecordSet.EOF 
    If someRecordSet!ColumnName <> "" Then
        ' do some logic
    End If
Loop

I'm wondering how to implement that same behavior (even though the "." is very much so not recommended to be used) in my own C# dll.

Any help would be most appreciated.

The solution was to define an indexer that works the same way

public object this[string param] {
    get {
        if (!dict.ContainsKey(param))
            return "";
        return dict[param];
    }
    set {
        dict[param] = value;
    }
}
