Is it possible to save value of txtSearche in array splitted into seperate words?
txtSearche = "put returns between paragraphs";
something like this:
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?
Yes try this:
string[] words = txtSearche.Split(' ');
which will give you:
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();
EDIT: Nakul to split by one space or more, just add them as parameters into the Split() method like below:
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
txtSearche.Split(new string[] { " " }, StringSplitOptions.RemoveEmptyEntries);
You could use String.Split.
Join.None of above work with multiple spaces or new line!!!
Here is what works with them:
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.
UPDATE
In fact this is better:
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
String.Split has an overload that takes an array of split characters, and an option to skip empty entries, so you could use text.Split(" \t\r\n\x85\xA0.,;:!?()-\"".ToCharArray(), StringSplitOptions.RemoveEmptyEntries). If you're going to go all the way to regex though, @"\W+(?<!')" would be better than @"\s+", since it would remove punctuation as well (the (?<!') is to protect contractions and possessives, with the unfortunate side effect that it won't remove single quotes).StringBuilder sb = new StringBuilder(txtSearche);
var result = sb.Tostring().Split(' ');
new StringBuilder(txt).ToString() = no-opIf 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.
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];
}
