自己用过的一些正则表达式，整理下方便后期再用...

//电信手机号码
string dianxin = @"^1[3578][01379]\d{8}$";
Regex numberd = new Regex(dianxin);
//移动手机号码
string yidong = @"^(1[34578][0123456789]\d{8}|134[012345678]\d{7})$";
Regex numbery = new Regex(yidong);
//联通手机号码
string liantong = @"^1[34578][01256]\d{8}$";
Regex numberl = new Regex(liantong);
//座机号码
string zuoji = @"^0[23456789][0123456789][23456789]\d{6}";
Regex numberz = new Regex(zuoji);

//字符串完全匹配内容：只允许输入0-9和*

var lamda = /^([*0-9]*)\d{0,11}$/;
result1 = lamda.test(isbusy);
