C＃ - 读取字符串集合中的特定行 [英] C# - Reading a Specific line in a string collection

问题描述

我不是真的不知道怎么回事，这是我的一半尝试，它实际上是不行的

I don''t don''t really know how, this is my half attempt on it, its oboiusly doesn''t work

int addnumber = 0;
       while (addnumber < Properties.Settings.Default.DatesEventNames.Count)
       {
           addnumber = addnumber + 1;
               DateTime yourDateTime = DateTime.ParseExact(item, "ddMMyyyy", CultureInfo.InvariantCulture);
       }

假设我有一个字符串集合中含有此字符串

Lets say I have a string collection with this in it

hi<br />
hi2<br />
hi3<br />
hi4

我只是想在我的文本框中看到h3，而不是所有这些，我希望能够通过行号读取行不是

and i just want to see h3 in my textbox, and not really all of them, I want to be able to read the line by the line number not

if(stringcollection.contains(h3)
{
}

所以我不想要包含字符串的方法，我想要的方法有点像

so I dont want the contains string method, I want the method that it kinda like

In (stringcollection.linenumber == 3)
{
textbox.text = the string's text on that line number
}

< br $> b $ b



这将是hi3。任何人都可以帮我解决这个问题吗？

and that would be "hi3". can anyone please help me out with this?

推荐答案

你有一个集合，你可以通过索引访问它。 myStringCollection [3]。此外，如果您想使用非连续索引来访问项目，您可以使用字典

You have a collection, you can access it by index. myStringCollection[3]. Also, you can use a dictionary if you want to use a non sequential index to access an item

Hi Tech，

i刚刚为您提供了样本帮助。 ...可能它可以帮助你

Hi Tech,

ArrayList list = new ArrayList();
       list.Add("hi1");
       list.Add("hi2");
       list.Add("hi3");
       foreach (string item in list)
       {

           int index=item.LastIndexOf('3');
           if (index==2)//**also u can use (index>1)
               Response.Write("hi3");
