如何用C＃中的单词将文本值拆分成数组？

Is it possible to save value of txtSearche in array splitted into seperate words?

是否有可能将txtSearche的值保存在分割成单独单词的数组中?

txtSearche = "put returns between paragraphs";

something like this:

像这样的东西:

 StringBuilder sb = new StringBuilder(txtSearche);

array1 = sb[1]   = put
array2 = sb[2]   = returns
array3 = sb[3]
array4 = sb[4]
array5 = sb[5]

how to do it correct?

怎么做对吗?

Yes try this:

是试试这个:

string[] words = txtSearche.Split(' ');

which will give you:

这会给你:

words[0]   = put
words[1]   = returns
words[2]   = between
words[3]   = paragraphs

EDIT: Also as Adkins mentions below, the words array will be created to whatever size is needed by the string that is provided. If you want the list to have a dynamic size I would say drop the array into a list using List wordList = words.ToList();

编辑:同样如下面Adkins所提到的,单词数组将被创建为提供的字符串所需的任何大小。如果您希望列表具有动态大小,我会说使用List wordList = words.ToList();将数组放入列表中。

EDIT: Nakul to split by one space or more, just add them as parameters into the Split() method like below:

编辑:Nakul分割一个或多个空格,只需将它们作为参数添加到Split()方法中,如下所示:

txtSearche.Split(new string[] { " ", "  ", "   " }, StringSplitOptions.None);

or you can tell it simply to split by a single space and ignore entries that are blank, caused by consecutive spaces, by using the StringSplitOptions.RemoveEmptyEntries enum like so

或者您可以通过使用StringSplitOptions.RemoveEmptyEntries枚举来简单地分隔单个空格并忽略由连续空格引起的空白条目

txtSearche.Split(new string[] { " " }, StringSplitOptions.RemoveEmptyEntries);

You could use String.Split.

你可以使用String.Split。

#3

Below example will split the string into an array with each word as an item...

下面的示例将字符串拆分为一个数组,每个单词作为项目...

string[] words = txtSearche.Split(' ');

string [] words = txtSearche.Split('');

None of above work with multiple spaces or new line!!!

以上都不适用于多个空格或新行!!!

Here is what works with them:

以下是它们的作用:

 string text = "hi!\r\nI am     a wonderful56 text... \r\nyeah...";
 string[] words =Regex.Split(text, @"\s+", RegexOptions.Singleline);

If you need to remove ellipsis then more processing is required and i can give you that as well.

如果你需要删除省略号,那么需要更多的处理,我也可以给你。

UPDATE

In fact this is better:

事实上这更好:

 string text = "hi!\r\nI am     a wonderful56 text... \r\nyeah...";
 MatchCollection matches = Regex.Matches(text, @"[\w\d_]+", RegexOptions.Singleline);
 foreach (Match match in matches)
 {
   if(match.Success)
      Console.WriteLine(match.Value);
  }

Outputs:

hi I am a wonderful56 text yeah

嗨,我是一个很棒的文字,是的

#5

StringBuilder sb = new StringBuilder(txtSearche); 

var result  =  sb.Tostring().Split(' ');

If you want a more complete solution and don't exactly worry about performance, you can have this one-liner take care of punctuation, etc. and give you an array of only the words.

如果你想要一个更完整的解决方案并且不要完全担心性能,你可以使用这个单线程序来处理标点符号等,并为你提供一系列单词。

string[] words = Regex.Replace(Regex.Replace(text, "[^a-zA-Z0-9 ]", " "), @"\s+", " ").Split(' ');

private void button1_Click(object sender, EventArgs e)
{
    string s = textBox1.Text;            
    string[] words = s.Split(' ');           
    textBox2.Text = words[0];
    textBox3.Text = words[1];
}
