string plit

string[] keywords;

char[] charSeparators = new char[] { ' ' };

keywords = aKeywords.Split(charSeparators,
StringSplitOptions.RemoveEmptyEntries);

foreach (string keyword in keywords)

{

MessageBox.Show(keyword);

_documentDA.DeleteDocumentKeyword(aDoc, keyword);

}

I can split the string into words if they are separated by a space.

How about if I have a string separated by space characters and return?

eg.

I entered "Hello world !" in the first line of a rich text box and press
"ENTER" key to the second line. Then enter "My name is Alan".

I just wonder the "!My" will be treated as one word.

Alan,

Why not try it yourself.

\\\
string myString = "What is \r\nthis";
char[] charSeparators = new char[] { ' ', '\r', '\n' };
string [] keywords = myString.Split(charSeparators,
StringSplitOptions.RemoveEmptyEntries);
foreach (string keyword in keywords)
{
MessageBox.Show(keyword);
}
///

I hope this helps,

Cor

Hi,

I almost can get my string split working, however, still got little problem.
I got a text file in which a strange character, ie a little rectangle at the
end of each line. So when I call string split, I also got the little
rectangle with the word.

eg.
Hello world enquiry

After the split I got
Hello
world
enquiry

this is my code:
string fileText;

string[] keywords;

char[] charSeparators = new char[] { ' ', '\r', '\n', ',', '\t' };

try

{fileText = File.ReadAllText(aFile);

keywords = fileText.Split(charSeparators,
StringSplitOptions.RemoveEmptyEntries);

....

}

catch

{

}

Alan,

Therefore you have to find what character is at the end of each line. Not
tested but written in this message I think that I would do it something like
this to see what it is.

string myString = "Whatever";
int Lastcharacter = myString[myString.Count];

You should than get the charatcter at the last line of your string.

Than you can set that as a char in your split.

I hope this helps,

Cor

Hi,

I think that little rectangle is a sort of non-Window thing, may like Linux
thing.
It appears as a little rectangle when I open the text file and using the
MessageBox.Show.

I think I cannot make it into
char[] charSeparators = new char[] { ' ', '\r', '\n', ',', '\t' };

Because there is no way to reproduce this little rectangle.
