i 寻找纬度和长度鉴定。
任何人都可以提出这种确认。
i 使用
if (Regex.IsMatch(textBox1.Text, "(?(?:90|(?:[0-8]?\d))([ -/])[0-5]?\d\1[0-5]?\d(\.\d{1,4})?\1[NS])") == true)
感谢大家。
证实扼杀是没有道理的,即数字。 第一号:
bool ValidateLongtitude(string txt) {
double value;
if (!double.TryParse(txt, out value)) return false;
return value >= -180 && value <= 180;
}
如果纬度在+/-90度之间(或+/-pi/2 radians),则纬度在+/-180度之间(或+/-pi radians)。
确实,不能给你比你更详尽地说明你重新谈论什么。
