我有TextBox和Textbox值来自数据库，例如此格式$:2000.00所以请告诉我如何在TextBox变量Double上获取数字

Answer 1

试试这个

var input = "$:2000.00";
Regex regex = new Regex(@"-?\d+(\.\d{1,2})?");
var match = regex.Match(input);            
if (match.Success)
{
    double d = double.Parse(match.Value);
}

var s = "$:2000.00";
var d = Double.Parse(s.Substring(2), System.Globalization.CultureInfo.InvariantCulture);
