You have not mentioned the scanned data that you are getting in textbox4.

Post that with expected output you want

Please aware that array indexing starts from 0 (zero) index
lines [0] instead of lines [1]

Thank you for reply
i added in my windows form textbox with multiline and i get result what i need
as following code
private void button1_Click(object sender, EventArgs e)
        {

                string[] lines = textBox4.Text.Split(new string[] { Environment.NewLine }, StringSplitOptions.None);
                textBox1.Text = lines[1].Substring(lines[1].IndexOf(":") + 1);
                textBox2.Text = lines[2].Substring(lines[2].IndexOf(":") + 1);
                textBox3.Text = lines[3].Substring(lines[3].IndexOf(":") + 1);



        }
But if i use key down event for textbox i recieve data in it
or using text changed event
i get error

{"Index was outside the bounds of the array."}

An unhandled exception of type 'System.IndexOutOfRangeException' occurred in

QrReaderSoftware.exe exception

in line red in key down exception show

I attached my sample with message
private void textBox4_KeyDown(object sender, KeyEventArgs e)
       {
           if (e.KeyCode == Keys.Enter)
           {
               string[] lines = textBox4.Text.Split(new string[] { Environment.NewLine }, StringSplitOptions.None);
               textBox1.Text = lines[1].Substring(lines[1].IndexOf(":") + 1);
               textBox2.Text = lines[2].Substring(lines[2].IndexOf(":") + 1);
               textBox3.Text = lines[3].Substring(lines[3].IndexOf(":") + 1);
           }

       }

What does it means?
textbox1 michel bondq Country
textbox3 part
textbox2 Egypt Membership
textbox1 have extra word country
textbox2 have extra word Mmebership
textbox3 is true

Its difficult to understand whats the output coming.

As your data is coming from the scanner is UserName : michel bondq,
Country : Egypt,
Membership : part

You need a seperator like as highlighted (if it was not gone for production), so that it will be differentiated between the strings, after doing changes, split the data by comma then split by colon.

@Thanks pointing out nitin sir

Or it would be helpful if you share your code

Can you please .zip and attach one sample text file here? It would be quicker to work with what you have and give a perfect working solution immediately.

The problem is, your text must be having new line characters, which you have omitted while putting those values in your code.

Please give the text file and one of us will post the answer.

Please i do as following
var data = "UserName: michel bondq Country: Egypt Membership : part";
           string[] sStringResult = data.Split(':');

           textBox1.Text = sStringResult[1];

           textBox2.Text = sStringResult[3];

           textBox3.Text = sStringResult[2];
Result
textbox1 michel bondq Country
textbox3 part
textbox2 Egypt Membership
textbox1 have extra word country
textbox2 have extra word Mmebership
textbox3 is true
so that if possible how to remove extra word from that
i can accept any solution for that]if that require to change formate i accept
but how to split without extra word

Hey Ahmed
Barcode scanner is like a keyboard, I personally think that when scanner scans a barcode, the it paste the scan data to any focus control followed by enter key.

So, to get the the data as expected, you can create a keydown event on textbox like:
private void textBox1_KeyDown(object sender, KeyEventArgs e)
        {
            if (e.KeyCode == Keys.Enter)
            {
               //split your data
              var data = "
UserName : michel bondq
Country : Egypt
Membership : part";
              string[] value= data.Split(':');
              var userName = value[0];
             var country = value[3];
             var  membership = value[5]
            }
        }
I believe that there is no direct way to do that.

Hope it helps:)
