在C＃中的字符串数组打印特定单词 [英] Print a specific word from a string array in c#

问题描述

我发现类似我的问题几个解决方案，但他们也没有什么帮助。我有一个包含几个字符串值的数组列表{苹果，香蕉，AppleBanana}

我希望能够从每个字符串中提取苹果。下面是一个提取字苹果。但我怎么从AppleBanana字提取苹果？

 的String [] = listOfString {苹果，香蕉，苹果，AppleBanana};
VAR的查询=从字符串我在listOfString
            我集团通过（i ==苹果）到appleString
            选择appleString;的foreach（查询VAR项）
{
    如果（item.Key ==真）
    {
        字符串[] = Applyby item.ToArray（）;        的foreach（在项目VAR ITEM2）
        {
            Console.WriteLine（ITEM2）;
        }
    }
}
 

解决方案

如何

 的String [] = listOfString {苹果，香蕉，苹果，AppleBanana};
VAR AppleItems = listOfString.Where（X =＆GT; x.Equals（苹果））;
的foreach（在AppleItems字符串项）
{
    Console.WriteLine（项目）;
}
 

收益苹果苹果

I found a few solutions similar to my question but they are not helpful. I have an array list containing few string values { "Apple", "Banana", "AppleBanana" }

I want to be able to extract Apple from each string. Below is an extraction word "Apple". But how do I extract Apple from AppleBanana word?

string[] listOfString = { "Apple", "Banana", "Apple", "AppleBanana" };
var query = from string i in listOfString
            group i by (i == "Apple") into appleString
            select appleString;

foreach (var item in query)
{
    if (item.Key == true)
    {
        string[] Applyby = item.ToArray();

        foreach (var item2 in item)
        {
            Console.WriteLine(item2);
        }
    }
}

解决方案

how about

string[] listOfString = { "Apple", "Banana", "Apple", "AppleBanana" };
var AppleItems = listOfString.Where(x => x.Equals("Apple"));
foreach (string item in AppleItems)
{
    Console.WriteLine(item);
}

returns Apple Apple
