Checking if a variable is of data type double

Question

I need to check if a variable I have is of the data type double. This is what I tried:

try
{
    double price = Convert.ToDouble(txtPrice.Text);
}
c         


        

Answer 1

Use the Double.TryParse method:

double price;
if (Double.TryParse(txtPrice.Text, out price))
{
    Console.WriteLine(price);
}
else
{
    Console.WriteLine("Not a double!");
}
