无法将'string'转换为'System.DateTime'

Question

I am having some overloaded method match for some invalid arguments.I'm guessing this is caused by my DateTime value.How do you convert it to string using sqlParemeters?

string quo_date = DateTime.Now.ToString();

 quotation1 quotations = new quotation1(quo_product,quo_custname
            ,quo_address,quo_desc,quo_date,quo_printProcess
            ,quo_contact,quo_quantity,quo_size,quo_numberOfPage,quo_cover
            ,quo_inside,quo_ofc,quo_ifc,quo_obc,quo_ibc,quo_onecolor
            ,quo_fullcolor,quo_file);

In my class I declared my datetime sqlPrameter into something like this

DateTime quo_date

Answer 1

I got the answer I just change this string quo_date = DateTime.Now.ToString();

To this DateTime quo_date = DateTime.Now;
