[RESOLVED] string problem

In my project, I have a multiline textbox (txtInput) in
the main form and the user inputs a list of strings. Then I have to copy the input data into an array of strings (StrArray) So I did this:

VB Code:

StrArray = txtInput.Text.Split(vbCr)
For i = 0 To StrArray.GetUpperBound(0)
    StrArray(i).Trim(vbCr) 
    'I trid StrArray(i).Replace(vbcr,"") also.
    'I tried to trim/replace vbcr,vbnewline and vblf
 
' to see the results
TextBox2.text &= strarray(i)
Next

But in the textbox2, I saw one special char in each string
except in the first string. I copied that special char and
pasted in notepad. That char is something like an 'enter key'
How can I remove it?

I tried this also

VB Code:

StrArray = txtInput.Text.Split(vbCr)
For i = 0 To StrArray.GetUpperBound(0)
    ListBox1.Items.Add(StrArray(i).Replace(vbLf, ""))
Next
ListBox1.Items.CopyTo(StrArray, 0)

Now it works fine. I want to know whether there is any method
to do this without using listbox.

Check the correction below, You were not assigning the modified(replace) value to anything.

VB Code:

Dim StrArray() As String, i%
        StrArray = TextBox1.Text.Split(vbCr.ToCharArray)
        For i = 0 To StrArray.GetUpperBound(0)
 
            StrArray(i) = StrArray(i).Replace(vbLf, " ")
 
            ' to see the results
            TextBox2.Text &= StrArray(i)
        Next

If you wanted to use the Split function you would use a different one:

VB Code:

StrArray = System.Text.RegularExpressions.Regex.Split(TextBox1.Text, Environment.NewLine)

Regex.Split allows you to split on a string instead of just a single character. The good news is that you don't have to use any method because you already have an array of individual lines in the RichTextBox.Lines property.

I thaught that StrArray(i).Replace(vbLf, " ") will change the original string. thanks for that.
Thanks jmcilhinney, I am going to use richtextbox.
