have a string for example:

string MySentence;

What I want to be able to do is parse that sentence and seperate all the words/entries that are seperated by a space into a seperate mini string/char array..

so, "this is my first sentence." would become:

[1] "this"
[2] " "
[3] "is"
[4] " "
[5] "my"
[6] " "
[7] "first"
[8] " "
[9] "sentence."

the reason I mention dynamic is that it is not possible to determine how many mini chunks are needed in advance -- depends what is contained in the string initially.

how is type of variable truncating / dynamic array scripted in c# / .net based pages?

string sample = "this is my first sentence.";
string[] words = sample.Split(' ');
foreach (string word in words)
{
Console.WriteLine(word);
}

After seeing what you actually need is not completely provided by string.split() method, but what it gives is the dynamic array but not including the spaces as needed by you

I recommend you to use the string.split() method but just keep in mind that every array member will be followed by a space character. Its just a programming logic and can be implemented quite easily

I am doing a little change to the code by kukno

string sample = "this is my first sentence.";
string sample1 = sample.Replace(" ", "* *");
string[] words = sample1.Split('*');
foreach (string word in words)
{
Console.WriteLine(word);
}

ok, got it -- works fine as written.

utilising one the example (via the url link provided).

is there a way to still have the 'chars' that have been stripped away to be kept?

i.e. ' ' '.' ',' etc... to be recorded on the next line (like the words seperated.

string inputValue = "this is my first sentence.";
 
            string[] inputWords = 
                inputValue.Split(new char[] { ' ', ',', ';', '.', '-', '/', '|', '\\',
                                              '%', '#', '@', '!', '~', '$', '^', '(',
                                              ')', '+', '[', ']', '{', '}', '"', ':', 
                                              '<', '>', '?',  '\r', '\n', '*' }, StringSplitOptions.RemoveEmptyEntries);
 
            foreach (string inputWord in inputWords)
            {
                Console.WriteLine(inputWord);
            }

the space is replaced with *space* and then split the content with * so that you will not loose the space and you will get the data as you wanted

[1] "this"
[2] " "
[3] "is"
[4] " "
[5] "my"
[6] " "
[7] "first"
[8] " "
[9] "sentence."

I used * assuming that your data will not contain * in it. You can use any character or character sequence in place of * only thing to be considered is that your regular data should not consist of this sequence
