正则表达式平时不常用，经常都是用的时候，临时抱佛脚，查文档，然后就是被各种坑之后，才会逐渐熟练。

先来看下代码和运行效果吧
string msg, rex; Match m; msg = "昨日总能耗0度。 (长沙市口腔医院)星期一【紫衡技术】"; rex = @".*(昨日总?能耗)([0-9]{1,}[.]?[0-9]*)*度。 \((.*)\)(.{3}).*"; m = Regex.Match(msg, rex); Console.WriteLine("0:" + m.Success); WriteGroupInfo(m); //1 msg = @"上周总能耗28401.4度。 (沙井街道办)星期一【紫衡技术】"; rex = @".*(上周总?能耗)([0-9]{1,}[.][0-9]*)*度。 \((.*)\)(.{3}).*"; //昨日总能耗2582.1度。【长沙市天心区人民法院】2018 - 07 - 08【紫衡技术】 m = Regex.Match(msg, rex); var r = m.Success; Console.WriteLine("1:"+r); WriteGroupInfo(m); //2 rex = @".*(昨日总?能耗)([0-9]{1,}[.]?[0-9]*)*度。\【(.*)\】(\d{4}-\d{2}-\d{2}).*"; msg= "昨日总能耗209.9度。【长沙市天心区人民检察院】2018-07-08【紫衡技术】"; Match m1 = Regex.Match(msg, rex); Console.WriteLine("2:"+m1.Success); WriteGroupInfo(m1); //3 rex = @".*(上周总?能耗)([0-9]{1,}[.]?[0-9]*)*度。 \((.*)\)(.{3}).*"; msg = "上周总能耗10922.4度。 (深圳市地方税务局第二稽查局)星期一【紫衡技术】"; m1 = Regex.Match(msg, rex); Console.WriteLine("3:"+m1.Success); WriteGroupInfo(m1); //4 rex = @".*(上月总?能耗)([0-9]{1,}[.]?[0-9]*)*度。 \((.*)\)(.{8}).*"; msg = "上月总能耗49276.9度。 (深圳市地方税务局第二稽查局)2018年06月【紫衡技术】"; m1 = Regex.Match(msg, rex); Console.WriteLine("4:"+m1.Success); WriteGroupInfo(m1); //5 rex = @".*(建筑名称)\：(.*)，在(\d{4}-\d{2}-\d{2}).{3}([0-9]{1,}[.][0-9]*)*度。"; msg = "建筑名称：长沙市天心区人民法院，在2018-07-08日用电2582.1度。"; m1 = Regex.Match(msg, rex); Console.WriteLine("5:"+m1.Success); WriteGroupInfo(m1); //6 rex = @"(今日能耗)\：([0-9]{1,}[.]?[0-9]*)"; msg = "今日能耗：300【紫衡技术】"; m1 = Regex.Match(msg, rex); Console.WriteLine("6:" + m1.Success); WriteGroupInfo(m1); //^【([^】]+)】异常(.+?)服务(【([^】]+)】未找到或者未安装！)*(服务【([^】]+)】未找到或者未安装！)*(服务【([^】]+)】未找到或者未安装！)*(服务【([^】]+)】未找到或者未安装！)

运行结果：
需要注意的地方，待匹配文字中的空格以及全角和半角字符要注意区分。
存储正则表达式字符串，不能存储到Json文件中，特殊字符会出现转义，存XML中没有这个问题。通过构造sql语句存储到mysql中的时候，反斜杠\将会被直接吃掉，所以插入之前要先进行转义。
var _TemplateReg = v.Value.TemplateReg.Replace("\\", "\\\\");
在C#中\\表示\，\\\\就表示\\。

我想直接通过代码来自动将其迁移到mysql数据库中去。
