c# - Input string was not in a correct format even i have the right values in it -

-

i have shopping cart website. when submit "submit order button" giving me error saying input string not in correct format. below, have code declared variables. 

public class shoppingcart {     public string categoryname;     public int categoryid;     public int productid;     public int customerid;      public string productname;     public string productimage;     public string productprice;     public string productdescription;     public int productquantity;      public string bankdepositimage;      public string customername;     public string customeremailid;     public string customerphoneno;     public string customeraddress;     public string productlist;     public string paymentmethod;      public string orderstatus;     public string orderno;      public int totalproducts;     public int totalprice;     public int stocktype;     public int flag;

in code textboxes.

shoppingcart k = new shoppingcart()             {                 customername = txtcustomername.text,                 customeremailid = txtcustomeremailid.text,                 customeraddress = txtcustomeraddress.text,                 customerphoneno = txtcustomerphoneno.text,                 totalproducts = convert.toint32(txttotalproducts.text),                 totalprice = convert.toint32(txttotalprice.text),                 productlist = productids,                 paymentmethod = rblpaymentmethod.selecteditem.text              };

i receiving error in shopping k = new shopping cart line of code. confused on problem given inputting right value on each text box. please , thank you

try using int32.parse 

totalprice = int32.parse(txttotalproducts.text)

and steve suggests, make sure input devoid of decimals.
