C# - Saving values in Listbox

Question

I have the following code:

SaveFileDialog saveGC1File = new SaveFileDialog();

private void GCSavePlacementOneButton_Click(object sender, EventArgs e)
{
    // Initialize the SaveFileDialog to specify the .txt extension for the file.
    saveGC1File.DefaultExt = "*.txt";
    saveGC1File.Filter = ".txt Files|*.txt|All Files (*.*)|*.*";
    saveGC1File.RestoreDirectory = true;

    try
    {
        string placementOneSave = placementOneListBox.Items.ToString();

        // Save the contents of the formattedTextRichTextBox into the file.
        if (saveGC1File.ShowDialog() == DialogResult.OK && saveGC1File.FileName.Length > 0)
            placementOneSave.SaveFile(saveGC1File.FileName, RichTextBoxStreamType.PlainText);

        // Throws a FileNotFoundException otherwise.
        else
            throw new FileNotFoundException();
    }

    // Catches an exception if the file was not saved.
    catch (Exception)
    {
        MessageBox.Show("There was not a specified file path.", "Path Not Found Error",
                        MessageBoxButtons.OK, MessageBoxIcon.Warning);
    }
}

However, using Visual Studio 2010, the line in the "if" loop that states:

"placementOneSave.SaveFile(saveGC1File.FileName, RichTextBoxStreamType.PlainText);"

Has a red line under the "SaveFile".. I have used this code to save a file before and am unsure why it will not work for a ListBox.

QUESTIONS

How can I save a ListBox in a similar way to a RichTextBox?
Any way to edit this code to make it have the user choose where the ListBox will be saved?

ListBox does not provide a method to save all its items to a file. The code snippet showing how this can be done is available here:
