how to find a word in c#

 
0
 

hi
I'm new to C# and I didn't have any programming skills.
I'm on my third week now and it seems it's quite complex

I would like to design a code, where it can determine the word type in the sentence.
So, first one must type a sentence and then on the second box, just type a word and check if its present in the first box (from the sentence you typed)
the result should show, true or false.

I started a code but I don't know how to continue: Any idea or suggestion is greatly appreciated:

 namespace DisplayWordJaNein
 public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            string yourSentence;
            string yourWord;

            yourSentence = textBox1.Text;
            yourWord = textBox2.Text;

            if

from here I'm not sure what to do. From what I've learned I have to use the type bool here. But don't know how to implement.

thanks & regards

hi again

i was able to finish it until here and it's working. But what I like is, it will display "Word Found" or let's say true if I'll write a word which is on the sentence itself.
ok, I tried to write: this is my first sentence
and on the 2nd box, if i write "sentence" only it displays "the word can't be found".

so i think i'm on the right track but i'd like that it will give me result "true" if the word i type is on the sentence

thanks

here is my code:

namespace DisplayWordJaNein
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            string yourSentence;
            string yourWord;

            yourSentence = textBox1.Text;
            yourWord = textBox2.Text;

            if (string.Equals(yourSentence,yourWord)) 
            { 
                label4.Text="Word Found!";
            } 
            else
            { 
                label4.Text="The word could not be found.";
            }

Well, google will perhaps help you in finding things in strings. There are a number of options you could use..

Look up the members of the String class.
From the code I see you use some Visual Studio.
In the menubar you will find something called "Help"
Click on it and choose Search. In the window that appears type String members
You will find what you where looking for.

Take a look at string.Contains() or string.Compare() instead of string.Equals(). You will also need to address the casing of the word (uppercase, lowercase).

private void Form1_Load(object sender, EventArgs e)
        {
            string sText="Sonia Sardana";
            if (sText.Contains("Sonia"))
            {
                MessageBox.Show ("contains"); 
            }
       }

Hi

I was able to find it. But my next problem is: I would like it that it will also accept the UPPERCASE or LOWERCASE letters if I type in the "enter word to compare".

So that means if I write in the first box like:

This is my sentence

And I'll write in my second box like:

SENTENCE,

that it wil also determine that way.
Is that posible?
Coz in my code, I wrote the big letters SENTENCE but then it didn't find the word.
Shall I make another method for that?
Thanks again

namespace DisplayWordJaNein
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            string yourSentence;
            string yourWord;


            yourSentence = textBox1.Text;
            yourWord = textBox2.Text;


            if (yourSentence.Contains(yourWord))
            {
                label4.Text = "Word Found! / ";
                         } 
            else
            { 
                label4.Text="The word could not be found.";
            } 
        }

then convert the strings to the same casing and test after.

Hi again,

ok I tried this one, but then it displays the word if I write the word. But the bug is if I only write a letter which a word has, it also displays "Word Found"

I would like that it will only determine the word not the characters.

In this program:
if I type on the first box:

This is my sentence

and type on the 2nd box:

sentence

it will give a result of word found

but then if i type in the first box:
s

it will give a result of word found.
any suggestions?

thanks

        if (yourSentence.Contains(yourWord.ToLower()))
        {

            label4.Text = "Word Found! / ";

        } 
        else
        { 
            label4.Text="The word could not be found.";
        }

yourWord = "s"
and yourSentence = "This is my sentence"
yourWord will 2 times be found in yourSentence!

why is that?
I just would like to display the word which I exactly type, not the letters.
is my code not correct?
thanks

Your code is correct.
What you see as a letter "s" is actually "seen" by the computer as a string. Even "" is a string!
The Contains method just checks if a string is contained in another string or not.
Possible remedy(by no means the best!) to your problem : Only continue if yourWord.Length is greather then 1.

hi ddanbe, thanks for the reply.

I think I got and it's working fine. Now this code will also display the word which is written for example in Uppercase or Lowercase.

this is what i did:

thanks guys. I'm starting to enjoy this stuff...
do you know a website where it gives "to do's" or "assignment" for C#. you know for beginners like me. I would like to do some practice. Thanks again

    private void button1_Click(object sender, EventArgs e)
    {
        string yourSentence;
        string yourWord;

        yourSentence = textBox1.Text.ToLower();
        yourWord = textBox2.Text.ToLower();



        if (yourSentence.Contains(yourWord))

        {
            label3.Text = "Word Found!";
        }

        else 
        {
            label3.Text = "The word can't be found!";
        }
    }
