Question

我有一个基于空格分割的字符串数组。现在，根据我的要求，我必须得到其内容中包含'/'的数组元素，但我无法得到它。我不明白如何实现它。

以下是我尝试过的代码：

 string[] arrdate = currentLine.Split(' ');

如何获取由/组成的数组元素？

Answer 1

试试这个：

 string[] arrdate = currentLine.Split(' ');
 var dateItems = arrdate.Where(item => item.Contains("/")).ToArray()

Answer 2

foreach (string s in arrdate)
{
   if (s.contains("/"))
   {
       //do something with s like add it to an array or if you only look for one string assign it and break out of the loop.
   }
}

Answer 3

如果你只想获得一个项目，那么试试这个

// split on the basis of white space
string[] arrdate = currentLine.Split(' ');

// now find out element with '/' using lambda
string item = arrdate.Where(item => item.Contains("/")).FirstOrDefault();

// if you don't want to use lambda then try for loop
string item;
for(int i = 0; i < arrdate.Length; i++)
{
if(arrdate[i].Contains("/"))
{
item = arrdate[i]
}
}

Answer 4

// split on the basis of white space
string[] arrdate = currentLine.Split(' ');

// now find out element with '/' using lambda
string item = arrdate.Where(item => item.Contains("/")).FirstOrDefault();

// if you don't want to use lambda then try for loop
string item;
for(int i = 0; i < arrdate.Length; i++)
{
if(arrdate[i].Contains("/"))
{
item = arrdate[i]
}
}
