namespace XML_Deletes
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button2_Click(object sender, EventArgs e)
        {

  //single indivual file
            var doc = XDocument.Load(@"C:\\Users\IT-Administrator\Desktop\21.xml");
            doc.Root.Elements("Incident")
         .GroupBy(s => (string)s.Element("Comment"))
         .SelectMany(g => g.Skip(1))
         .Remove();
//doc.Save(@"C:\Users\IT-Administrator\Desktop\22.xml");
        }

        private void button1_Click(object sender, EventArgs e)
        {
            OpenFileDialog openFileDialog1 = new OpenFileDialog();

            openFileDialog1.Filter = "XML files(.xml)|*.xml|all Files(*.*)|*.*";
            openFileDialog1.FilterIndex = 1;

            openFileDialog1.Multiselect = true;

            if(openFileDialog1.ShowDialog() == DialogResult.OK)
            {
                {
    if (!String.Equals(Path.GetExtension(openFileDialog1.FileName),
                       ".xml",
                       StringComparison.OrdinalIgnoreCase))
    {
        // Invalid file type selected; display an error.
        MessageBox.Show("The type of the selected file is not supported by this application. You must select an XML file.",
                        "Invalid File Type",
                        MessageBoxButtons.OK,
                        MessageBoxIcon.Error);

    }
    else
    {
    }
}  }
    }

}

您在寻找XDocument.Save吗？

doc.Save(@"C:\\Users\IT-Administrator\Desktop\21.xml");

那已经存在于您的代码中（虽然它被注释掉了吗？）。你有保存问题吗？
