[英]How to find pattern in string and cut out part that contains that pattern - C#
我需要在字符串中找到模式,然后切出包含該模式的整個部分。 我將舉一個例子,我需要做什么:
我有這樣的字符串:
string text = "Some random words here EK/34 54/56/75 AB/12/34/56/BA1590/A and more random stuff...";
在該字符串中,我想檢查此模式是否存在:
string whatImLookinFor = "12/34/56/";
並且如果它在我的字符串中,那么我想剪切出包含我的模式的整個代碼,並用空格分隔:
AB/12/34/56/BA1590/A
您可以使用正則表達式或簡單的字符串操作來解決它。
這是使用簡單的字符串操作:
using System;
using System.Linq;
public class Program
{
public static void Main()
{
var text = "Some random words here EK/34 54/56/75 AB/12/34/56/BA1590/A and more random stuff...";
var whatImLookinFor = "12/34/56/";
// check if text contains it _at all_
if (text.Contains(whatImLookinFor))
{
// split the whole text at spaces as specified and retain those parts that
// contain your text
var split = text.Split(' ').Where(t => t.Contains(whatImLookinFor)).ToList();
// print all results to console
foreach (var s in split)
Console.WriteLine(s);
}
else
Console.WriteLine("Not found");
Console.ReadLine();
}
}
輸出:
AB/12/34/56/BA1590/A
