清除字符串中的字符 [英] Cleaning characters from a string

问题描述

  string  schoollist = '  102'，'  11'，'  23'，'  34 ' 
  string  [] SchoolListArr = schoollist.Split（' ，）; 
 
  for （ int  i =  0 ; i <  SchoolListArr.Length; i ++）
 {
  / /   Console.WriteLine（学校列表：+ SchoolListArr [i]）;  
 
  //   String s = null;  
 
  String  [] schools =  new   String  [ 100 ]; 
 
学校[i] = SchoolListArr [i]; 
 
 Console.WriteLine（ 学校名单： +学校[i ]）; 
 
} 
 Console.ReadLine（）; 
 
  //  现在我的问题是如何从字符串中删除（''）所以我有 
 
  102  
  11  
  //  而不是 
 '   102' 
 '  11 ' 
 
  //  谢谢 

解决方案

首先，您在问题中输入的代码将无法编译。

string schoollist ='102'，'11'，'23'，'34'需要 string schoollist ='102'，'11'，'23'，' 34';



为了替换字符串中的值，您可以非常简单地使用字符串。替换（）已满足hod。

schoollist = schoollist.Replace（\'，string.Empty）;



有关string.Replace的更多信息： MSDN文档 [ ^ ]

尝试：

  string  schoollist =  '102'，'11'，'23'，'34'; 
 schoollist = schoollist.Replace（ '， ）;  //  < ==添加此行 
  string  [] SchoolListArr = schoollist.Split（' ，'）; 

您还需要用引号括住 schoollist 字符串，并在行尾添加分号，否则它会赢得'编译。



希望这会有所帮助。

这是你可以使用string.Trim（params char）的一种方法。 []）

 Console.WriteLine（学校名单：+学校[i] .Trim（char.Parse（'） ）））; 

string schoollist ='102','11','23','34'
string[] SchoolListArr = schoollist.Split(',');

for (int i = 0; i < SchoolListArr.Length; i++)
{
    //Console.WriteLine("The school List:" + SchoolListArr[i]);

 //   String s = null;

    String[] schools = new String[100];

    schools[i] = SchoolListArr[i];

    Console.WriteLine("The school List:" + schools[i]);

}
Console.ReadLine();

// now my question is how do I strip ( ' ') from the  string so that I have 

102
11
// instead of 
'102'
'11'

// thank you

解决方案

For starters, the code you have put in your question will not compile.
string schoollist ='102','11','23','34' would need to be string schoollist ="'102','11','23','34'";

In order to replace values in a string, you could very simply use the string.Replace() method.
schoollist = schoollist.Replace("\'", string.Empty);

For more info on string.Replace: MSDN documentation[^]

Try:

string schoollist = "'102','11','23','34'";
schoollist = schoollist.Replace("'", ""); // <== add this line
string[] SchoolListArr = schoollist.Split(',');

You also need to surround your schoollist string with quotes and add a semicolon at the end of the line, otherwise it won't compile.

Hope this helps.

This is one way you could do it, using string.Trim(params char[])

Console.WriteLine("The school List:" + schools[i].Trim(char.Parse("'")));
