在asp.net c＃中从主字符串中查找所需的字符串 [英] Find required strings from main string in asp.net c#

问题描述

我有一个字符串，例如学校名称为{SchoolName}，学校联系电话为{SchoolPhone}，电子邮件为{SchoolEmail}



i希望查找{}中包含的所有标签并将其放入集合或字符串数​​组。怎么做？

解决方案

使用正则表达式匹配模式{}。

使用一些标准字符串命令 -

string.subString [ ^ ]

string.indexOf [ ^ ]

string.split [ ^ ]

  var  givenString = 
  学校名称为{SchoolName}，学校联系电话为{SchoolPhone}，电子邮件为{SchoolEmail}; 
  const   string  START_CHAR =   {; 
  const   string  END_CHAR =  }; 
  var  result =  new  List< string>（）; 
  while （givenString.IndexOf（START_CHAR，System.StringComparison.Ordinal）>  -1 ）
 {
  var  startIndex = givenString.IndexOf（START_CHAR，
 System.StringComparison.Ordinal）; 
  var  endIndex = givenString.IndexOf（END_CHAR，
 System.StringComparison.Ordinal）; 
 
 result.Add（givenString.Substring（startIndex +  1 ，endIndex-startIndex-1））; 
 givenString = givenString.Substring（endIndex + 1）; 
} 

I have a string e.g. School name is {SchoolName} and school contact number is {SchoolPhone} and email is {SchoolEmail}

i want to find all the tags wrapped in {} and put them in collection or string array. How to do this?

解决方案

use Regular expression to match the pattern {}.

Use some of standard string commands -
string.subString[^]
string.indexOf[^]
string.split[^]

var givenString =
                "School name is {SchoolName} and school contact number is {SchoolPhone} and email is {SchoolEmail}";
            const string START_CHAR = "{";
            const string END_CHAR = "}";
         var result=new List<string>();
         while (givenString.IndexOf(START_CHAR, System.StringComparison.Ordinal) > -1)
            {
                var startIndex = givenString.IndexOf(START_CHAR, 
             System.StringComparison.Ordinal);
                var endIndex = givenString.IndexOf(END_CHAR, 
                System.StringComparison.Ordinal);

                result.Add(givenString.Substring(startIndex + 1,endIndex-startIndex-1));
                givenString = givenString.Substring(endIndex+1);
            }
