1.是否是电话号码
代码语言:javascript复制public static bool IsPhoneOK(string num)
{
if (num.Length < 11)
{
return false;
}
//电信手机号码正则
string dianxin = @"^1[3578][01379]d{8}$";
Regex regexDX = new Regex(dianxin);
//联通手机号码正则
string liantong = @"^1[34578][01256]d{8}";
Regex regexLT = new Regex(liantong);
//移动手机号码正则
string yidong = @"^(1[012345678]d{8}|1[345678][012356789]d{8})$";
string phone = @"^1([38][0-9]|4[579]|5[0-3,5-9]|6[6]|7[0135678]|9[89])d{8}$";
Regex regexYD = new Regex(yidong);
Regex phoneRe = new Regex(phone);
if (regexDX.IsMatch(num) || regexLT.IsMatch(num) || regexYD.IsMatch(num) || phoneRe.IsMatch(num))
{
return true;
}
else
{
return false;
}
}
2.密码中为数字和字母组成,至少包含1个大写或者1个小写 例如:123456a
代码语言:javascript复制Regex reg = new Regex(@"^(?=.*[A-Za-z])(?=.*d)[A-Za-zd]{6,10}$");
return reg.IsMatch(str);
