Copy items in listbox1...? C#

Question

0.00/5 (No votes)

See more:

This is the code below using to copy items in listBox1, and it works.
If possible I would like to edit this code, so that to copy only part of the item, not the whole item.

example:
if the content item:

1. Name Surname
be copied only: Name Surname
but not to be copied: 1. Name Surname (1. - not to be copied)

Note: 1. is always in a series, and 1. does not change.

C#

private void Copy()
{
    StringBuilder sb = new StringBuilder();

    foreach (string sLine in listBox1.SelectedItems)
    {
        sb.Append(sLine + Environment.NewLine);
    }

    if (!string.IsNullOrEmpty(sb.ToString()))
    {
        Clipboard.SetText(sb.ToString(), TextDataFormat.Text);
    }
}

What I have tried:

C#

Clipboard.SetText( string.Concat( listBox1.SelectedItems.Cast<string>().Select( item =>
 Regex.Match( item, @"^\d+\.\s+(.+)" ).Groups[1].Value + Environment.NewLine ) ) );

But this is not the solution ...

Does each Item of your Listbox begin with '1.' ?
Or does each Item begin with a (incrementing) number followed by a Dot ?

Which platform you use when implement your app? (Winform, wpf, etc...)

The simplest way is to check if it exists and if so, discard it:

C#

string addme = sLine;
Match match = Regex.Match(sLine, @"(?<=1\.\s+).*");
if (match.Success)
    {
    addme = match.Value;
    }
sb.AppendLine(addme);

Clipboard.SetText(string.Join(Environment.NewLine,
    listBox1.SelectedItems.Cast<string>()
        .Select(item=>Regex.Match(item, @"^\d+\.\s+(.+)"))
        .Where(match=>match.Success)
        .Select(match=>match.Groups[1].Value)
    ));

Maybe I'm wrong but this is a very generic question: how can I cut off a part of a string?

In your case you get a string "1. Name Surname" and need to cut off the leading "1." like e.g. this:

C#

foreach (string sLine in listBox1.SelectedItems)
{
   //sb.Append(sLine + Environment.NewLine);
   sb.Append(sLine.Replace("1.", "") + Environment.NewLine);
}

Better you use the regular expression - this is very good documented as well, e.g. Regex.Replace-Methode (String, String)[^]
