转义符的总结:
开始数
………………………………………………………….
3 )Regex.matches() 提取所有符合要求的字符串
string str=@"绩大于80,则奖励50元.语文成绩等于100并且音乐成绩大于70,则奖励100元";
MatchCollection matches = Regex.Matches(str, "[0-9]+"); //用 MatchCollection 类型的变量存储匹配到的字符
foreach (Match mc in matches) //遍历输出得到的字符串
{
Console.WriteLine(mc.Value);
}
Console.ReadKey();
………………………………………………………….
4)Regex.Replace 替换字符串 有两种替换方式
方式1:
str = Regex.Replace(str, "aa+", "");
方式2:
string bir = "我的生日是05/21/2010耶";
string result = Regex.Replace(bir,@"(\d{2})/(\d{2})/(\d{4})","$3-$1-$2");
………………………………………………………….
5)Regex.Split 分割:
string str1="jfgdjgkhgkeydijf;ldfjgldfkey";
string[] strArr = Regex.Split(str1, "key.");
for (int i = 0; i < strArr.Length; i++)
{
Console.WriteLine(strArr[i]);
}
Console.ReadKey();
