Theres an issue with the whitespacehandling, which i am unable to solve

public void XMLWrite_Click(object sender, EventArgs e)
        {

            XmlDataDocument xmlDatadoc = new XmlDataDocument();
            xmlDatadoc.DataSet.WriteXml(txtXMLFilePath.Text);
            DataSet ds = new DataSet("Book DataSet");
            ds = xmlDatadoc.DataSet;
            dataGridView1.DataSource = ds.DefaultViewManager;
            dataGridView1.DataMember = "Book";

            if (File.Exists(txtXMLFilePath.Text))
            {
                XmlTextWriter writer = new XmlTextWriter(txtXMLFilePath.Text);
                writer.WhitespaceHandling = WhitespaceHandling.None;

                writer.Close();
            }

            else
            {
                MessageBox.Show(txtXMLFilePath.Text + " Error Writing XmlFile");
            }

推荐答案

您没有尝试写任何东西，那么您如何期望某些东西可以起作用"呢?另外，为什么还要检查该文件是否存在?是否存在如果没有，它将创建，如果没有，它将被覆盖.

You are not trying to write anything, so how can you expect something to "work"? Also, why would you check up that the file exists? If may exist or not; it if does not, it will be created, if not — overwritten.
