如何编写正则表达式来搜索单词中的一组字符 [英] How do i write a regex for searching a set of characters in a word

问题描述

我需要在字符串值列表中搜索，例如，

[银行A / c，银行OD A / c，手头现金，存款，杂项债务人，杂项债权人，杂项，...]



如果我在搜索框中输入'Ba'，它必须将结果集返回给我：

[Bank A / c，Bank OD A / c]



或如果我输入'或'，它必须返回给我包含字符串的结果集：

[Sundry Debtors，Sundry债权人]



我尝试过：



1. [_typedName] +

2. _typedName +

3. _typedName *

I need to search among a list of string values, for e.g.,
[Bank A/c, Bank OD A/c, Cash in hand, Deposits, Sundry Debtors, Sundry Creditors, Miscellaneous, ...]

If I type 'Ba' in the search box, it must return me result set as:
[Bank A/c, Bank OD A/c]

or if I type 'or', it must return to me result set containing strings:
[Sundry Debtors, Sundry Creditors]

What I have tried:

1. [_typedName]+
2. _typedName+
3. _typedName*

推荐答案

I强烈建议通过这个

不是正则表达式。有太多的模式可供匹配。相反，尝试并适应这个例子：

Not Regex. There have too many patterns to match. Instead, try and adapt from this example:

using System;
using System.Collections.Generic;

public class Program
{
	public static void Main()
	{
		var list = new List<string>();
		list.Add("Bank A/cat");
		list.Add("Bank OD A/c");
		list.Add("Cash in hand");
		list.Add("Deposit");
		list.Add("Sundry Debtors");
		list.Add("Sundry Creditors");

        // Your search string here
        string search="or";		
			
		foreach (string element in list)
		{
			if (element.IndexOf(search) != -1)
			{
				Console.WriteLine(element);
			}
		}
	}
}
