我有以下代码:

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);
    }
}

但是,使用Visual Studio 2010,“if”循环中的行指出:

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

在“SaveFile”下面有一个红色行。我之前使用过此代码来保存文件,并且不确定它为什么不能用于ListBox。


问题

  • 如何以类似于RichTextBox的方式保存ListBox?
  • 编辑此代码的任何方式都让用户选择ListBox的保存位置?

ListBox不提供将所有项目保存到文件的方法。有关如何完成此操作的代码段,请访问:
