How to add Filter with isEmpty or GreaterThan condition for a column ?

Hi expert ,

I am able to add normal filter for a field to read multiple data from a table e.g

Cutomer_Binding oNavBindingCustomer = new Cutomer_Binding();

List<Cutomer_Filter> filterArrayCustomer = new List<Cutomer_Filter>();

Cutomer_Filter customerFilter = new Cutomer_Filter();

customerFilter.Field = Cutomer_Fields.WCode;

customerFilter.Criteria = strWCode;

filterArrayCustomer.Add(customerFilter);

oNavBindingCustomer.UseDefaultCredentials = true;

Cutomer[] list = oNavBindingCustomer.ReadMultiple(filterArrayCustomer.ToArray(), null, 2000);

Now I want to add filter with not Empty or Greater-than condition for a column . Please help me how i can able to read multiple data from a table with empty or GreaterThan condition ? and if it can be possible another process please give me suggestion

Thanks
