attach a Text File in reply From which you want to read all the words !

Hi sahid raja,

I have tested and its working fine. Please try the following.

StreamReader sreader = new StreamReader(@"c:\ReadWords.txt"); //path of the file
string strFileContent = sreader.ReadToEnd(); //Read all the content
sreader.Close();
string[] words = strFileContent.Split(new char[] { ' ', '\r', '\n' },StringSplitOptions.RemoveEmptyEntries); //Split by words and remove new lines empty entries
ddlWords.DataSource = words; //Create the drop down list and assign it to the control.
ddlWords.DataBind();

If this helps you to get the answer then mark it as "Accepted Answer"

A string in .NET is just a sequence of unicode characters.

You can use the string's indexer to pick out the character at a particular index (starting from 0).

So, if you have this string:

string s = "$ab = 2;";

then:

char c0 = s[0]; // $
char c1 = s[1]; // a
char c2 = s[2]; // b

You can also convert a string to a char array:

char[] chars = s.ToCharArray();

or iterate through the characters one by one:

string message = "";
foreach(char c in s) message += c.ToString() + "\r\n";
MessageBox.Show(message); // displays characters vertically from top

If the words are on separate lines, like this say:

The quick brown fox jumped over the lazy dog
Pack my box with five dozen liquor jugs

then this revised code should work:

string filePath = @"c:\words.txt"; // or whatever the path is
string text = System.IO.File.ReadAllText(filePath);
string[] words = text.Split(new char[]{' ', '\r', '\n'}, StringSplitOptions.RemoveEmptyEntries);
listBox1.DataSource = words;

hello Vulpes

Many thanks for your reply..
but i have tried this..

if I have following text in file

The quick brown fox jumps over the lazy dog

then it works ok..

But when i Put some more text in a new line in file then it is not working Ok

It is splitting only first line in file..

Well, it depends how the words are laid out in the file.

Suppose for example the file contains the following sentence:

The quick brown fox jumps over the lazy dog

Then you could load the file, split it into words and display them in a ListBox in a Windows Forms application with the following code:

string filePath = @"c:\words.txt"; // or whatever the path is
string text = System.IO.File.ReadAllText(filePath);
string[] words = text.Split(' ');
listBox1.DataSource = words;
