asp.net - 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 a c# variable? I have a html textbox with Id txtCost and that will hold a double value. Thanks in advance.

Answer 1

您需要double.Parse()像这样解析值：

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

尽管解析数值有一些全球化警告（比如它如何解析点和逗号）。您可以在MSDN上阅读有关 parse 方法的更多信息

Answer 2

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