Taxable invoice detail line

Hi,

 

I am using .NET SDK and I am reading the detail lines from an invoice with the class "SalesInvoiceSalesLine" and all goes fine, but when I need to know if the detail line is taxable or not I do not find any property that indicates it.

 

I was thinking to use the property "SalesTaxType", it returns an integer, and after that, get the "sales tax type array" to know if the index returned by the property "SalesTaxType" is taxable or exempt, I did it with the COM SDK, but in .NET SDK I do not find any sales tax type array.

 

Is there any way to know when a detail line is taxable?? 

 

Also is there any way to get the tax rate for the invoice..?? not the Tax Agency ID, I would like to have the tax percent.
