c# write an arraylist to a text file

Question

I need to write my array list into a text file and so far have come up with this code. Now im confused as to how to write the 'line' to my text file using the textwriter? One procedure loads the list out of a txt file below.

public void LoadArrayList()
{
TextReader tr;
tr = File.OpenText("C:\\Users\\Mirro\\Documents\\Visual Studio 2010\\Projects\\Assessment2\\Assessment2\\act\\actors.txt");
string line = tr.ReadToEnd();
Console.WriteLine(line);
if (line != null)
{
    ActorArrayList.Add(line);
}
else

 tr.Close();
}

Then i have one that will populate the combo box in my form.

public void PopulateActors()
{
  cboActor.Items.Clear();
  foreach (string line in ActorArrayList)
        {
            cboActor.Items.AddRange(File.ReadAllLines("C:\\Users\\Mirro\\Documents\\Visual Studio 2010\\Projects\\Assessment2\\Assessment2\\act\\actors.txt")); 
        }
}

and this procedure i need it to write my whole array "ActoryArrayList" into the text file.

public void WriteArrayList()
{

}

Im sorry for being confusing originally.

Answer 1

Try with following code

        // Example #1: Write an array of strings to a file. 
        // Create a string array that consists of three lines. 
        string[] lines = { "First line", "Second line", "Third line" };
        // WriteAllLines creates a file, writes a collection of strings to the file, 
        // and then closes the file.
        System.IO.File.WriteAllLines(@"C:\Users\Mirro\Documents\Visual Studio 2010\Projects\Assessment2\Assessment2\act\actors.txt", lines);

OUTPUT :

     //   First line 
     //   Second line 
     //   Third line

The best way is @Leez's way, but You also may use TextWriter and foreach operator to make this:

        //your array
        string[] yourArray = { "fisrt", "second", "third" };
        string text = "C:\\Users\\Mirro\\Documents\\Visual Studio 2010\\Projects\\Assessment2\\Assessment2\\act\\actors.txt";
        using (TextWriter writer = File.CreateText(text))
        {

            foreach (string i in yourArray)
            {
                writer.WriteLine(i);
            }
        }
