asp.net - How to change the culture of a number in C#? -

-

i'm sending parameters paypal hidden form vars.

but site's culture danish. "50,00" value "amount_1" 

<input type="hidden" name="amount_1" value="50,00" />

i'm using code converts 50 "50,00"

item.pricepaid.tostring("#.00")

i believe number should like: "1234.56" there way set culture en-us on process? (not side wide) or better way this?

thanks!

you use overload of tostring takes iformatprovider , use getcultureinfo pass in required culture info:

item.pricepaid.tostring("#.00", cultureinfo.getcultureinfo("en-us"));

alternatively, (probably) specify invariant culture rather "en-us":

item.pricepaid.tostring("#.00", cultureinfo.invarianculture);
