I tried this it gives the correct num of character but not give the num of word.

What I have tried:

C#

if (txtStringName.Value != " ")
{
    str = txtStringName.Value.ToString().Trim();
    for (i = 0; i != str.Length; i++)
    {
        ch++;
        if (str == " ")
            word++;
    }
}

Split on spaces for words then count the characters.

Mehdi Gholam 3-Jun-16 4:51am

Lookup string.Split()

i get character count perfect but i cant get the word count

You're always checking the whole string to be a space (if (str = " ") rather than the specific character (something like if (Char.IsWhiteSpace(str[i]) ) - that's why your current code doesn't work. Split() would also do the job as Mehdi suggests but it wouldn't be suitable for large bodies of text as you'd be creating a huge number of objects.

thanx peejayadams
i do apply your suggestion in if loop it gives the ans but not correct
i enter 3 word but it shows only 2

shukla parth 3-Jun-16 5:14am

if (txtStringName.Value != " ")
{
str = txtStringName.Value.ToString().Trim();
str.Split();
for (i = 0; i != str.Length; i++)
{
ch++;
if ((Char.IsWhiteSpace(str[i])))
word++;
}
this is my code i take both word and ch =0

Hi shukla, by counting the spaces your always going to miss the last word so you'd need to increment your count by one for the final result.

shukla parth 3-Jun-16 5:19am

how can i do and where it will be applied

PeejayAdams 3-Jun-16 5:24am

You need to do it anywhere after the for loop. Check that word is non-zero so that you don't get a result of 1 where you should be getting zero so if (word > 0) word += 1; would do the job.

shukla parth 3-Jun-16 5:31am

thanks a lot peejayAdams...it completely work

shukla parth 3-Jun-16 6:24am

Solution 4

Just for the fun of it you can do it with two regular expressions.

C#

int wordCount = Regex.Matches(txtStringName.Value, "\\w+").Count;
int charCount = Regex.Matches(txtStringName.Value, "\\w").Count;

hello i do all thing but if i put double space it count as word
i mean i write asd asd
it shows 3 word

George Jonsson 3-Jun-16 9:10am

That's weird. It works for me with that string, 2 word and 6 characters.
What kind of animal is txtStringName.Value?
Is it s string or an object?
Maybe you have to write txtStringName.Value.ToString()

Nah, that shouldn't matter. Forget that

If you use the debugger, what is the string value of txtStringName.Value?

Sergey Alexandrovich Kryukov 3-Jun-16 16:45pm

5ed. This is the only reasonable answer so far. And this is not because of your use of Regex, this is because other do all those check if string is not " " or "" (as if " " or " " doesn't count) and other pointless things, such as splitting by " " (and what to do with "word, word" then?)...

Thanks Sergey.
It is just one way to do it and it is pretty straightforward and simple.

Hello, refer this code,

C#

int NoOfWords = 0;
int NoOfChars = 0;
string objText = textBox1.Text.Trim();

string[] words = objText.Split(' ');
NoOfWords = words.Length;

foreach (string word in words)
{
    NoOfChars += word.Length;
}

MessageBox.Show(string.Format("Words {0} and Chars {1}", NoOfWords, NoOfChars));

Just do some analysis, and think logically before implementing, because it is a very simple scenario.

Karthik_Mahalingam · Answer 3 · 2016-06-02T23:01:00

try this

C#

string Value = "Today is Friday";
       int CharCount = 0;
       int wordsCount = 0;
       if (Value != "")
       {
           wordsCount++;
           for (int i = 0; i < Value.Length; i++)
           {
               CharCount++;
               if (Value[i] == ' ')
                   wordsCount++;
           }
       }

       Console.WriteLine("Char Count = " + CharCount);
       Console.WriteLine("Words Count = " + wordsCount);
       Console.ReadKey();

Simplest way is

C#

CharCount = Value.Length;
 wordsCount = Value.Split(' ').Length;

Refer Following code to count Char and Word:

C#

var str = string.Empty;
        int ch = 1;
        int word = 0;

        if (txtStringName1.Value != " ")
        {
            str = txtStringName1.Value.ToString().Trim();

            for (int i = 1; i < str.Length; i++)
            {
                ch++;
                if (char.IsWhiteSpace(str[i - 1]) == true)
                {
                    if (char.IsLetterOrDigit(str[i]) == true ||
                        char.IsPunctuation(str[i]))
                    {
                        word++;
                    }
                }
            }
            if (str.Length > 2)
            {
                word++;
            }
        }

        Response.Write( "Char Count:" + ch +"  Word Count:" + word);
    }
