Add a character on each line of a string

Question

I make a CSV converter, for this, I need to replace all the spaces with \";\". I have already did this step. The problem is that I have a texbox with the multiline mod. Here is

Answer 1

content1 seems to contain the whole file.

So if you want to add semicolons to each line, you could replace the newline with a semicolon and a newline.

content1 = content1.Replace("\n", ";\n");

You can make your code a bit easier:

string nom = tbxNom.Text;
#region Normal
try
{
    string content1 = tbxArret.Text;
    string path1 = @"C:\Users\DanyWin\Desktop\CsvOutput\" + nom + ".csv";
    var lines = content1.Split(new[] { Environment.NewLine }, StringSplitOptions.RemoveEmptyEntries)
                .Select(line => Regex.Replace(line, @"\s+", ";") + ";");
    content1 = String.Join("\n", lines);
    File.WriteAllText(path1, content1);
}
catch
{
    lblInfo.Text = "Erreur";
}
