输入的字符串格式不正确

Question

I want to store result of total & tempDiscRs into b1..while storing it throws the error that Input string was not in correct format

decimal b1 = Convert.ToDecimal(lblDisRate.Text);
b1 = total * tempDiscRs;

Answer 1

You should be aware of the culture you're in.

Example: In US, the comma separator is a dot (.) while in Germany it is a comma (,).

Try

lblDisRate.Text.ToString(System.Globalization.CultureInfo.InvariantCulture)

In order to use Invariant Culture so you always use a dot instead of a comma.

Answer 2

decimal myValue;
if(Decimal.TryParse(lblDisRate.Text, out myValue))
{
   //correct
}
else
{
   //wrong
}
