Create “Protected ReadOnly Property AllFieldNamesStringCollection() As StringCollection” method for use with QueryInformation objects.  Currently, you must use the following construct (C#):

string[] allFields = this.AllFieldsList.ToArray();

queryInfo.Fields = StringBasics.CreateStringCollection(allFields);

This should be encapsulated in this new method as follows:

You can add the fields through the AllFieldsList property with one line of code (after the QueryInformation constructor).

QueryInformation info = new QueryInformation();
info.Fields.AddRange(this.AllFieldsList.ToArray());

There's no need to create another string collection object, since the QueryInformation class is initialized with an empty string collection.  Just AddRange the fields list to an array.
