storing a double type value from html textbox into a c# variable

Question

Does anyone know that how to store a double type value from html textbox into ac# variable? I have a html textbox with Id txtCost and that will hold a double value. Thanks in advance.

Answer 1

You need to parse the value using double.Parse() like so:

var value = double.Parse(txtCost.Text);

Although parsing numerical values has some globalization caveats (like how it parses dots and commas). You can read more about the parse method at MSDN

Answer 2

Double val=Convert.ToDouble(txtCost.Text);
