What's the value of Label13.Text?

iamsuntosh 8-Mar-13 9:42am

It is price of a product.. session variable

Thomas Daniels 8-Mar-13 9:44am

Yes, but what's the value of Session["Price"].ToString();
I know it's a price of a product, but what's the exact value?

1500

What's the error?

iamsuntosh 8-Mar-13 9:52am

input string is not in correct format

"1500" can be parsed to an int and is the correct format so you have something else in that string that is causing it to error.

Solution 1

Does it have a "$" in the field? If so, you can use:

int Price1 = int.Parse(Label13.Text, System.Globalization.NumberStyles.Currency);

must value of your label (actually your session) be a type which could cast to int!
this types can convert to int type!
decimal , float, double ,uint , long , ulong
must be in a correct format for casting to int!
its mean this cant parse
s22
but this can :
22
check this links :
conversion table

Solution 3

Try using Convert.ToDouble

if this still doesn't work, try applying regex to extract the digits in string format.
and then Convert.ToDouble()

Solution 4

personally I would check that the conversion can happen first

C#

int Price = 0;
if(int.tryparse(label13.Text, out Price) == true)
{
  //do whats needed here
}

Further Reading:
int.parse[^]
int.tryparse[^]

Solution 5

Why not do

C#

int Price1 = int.Parse(Session["Price"]);

Maybe the label text havent been set depending on what event you are parsing the int from?
