When implemented on xml configuration file for reading and writing the node above, find a problem,

Is the content of the node is null the corresponding xml file node wrap, then use the next time you read

achieve

Save method is used:

 public static Boolean  WriteXml(XmlDocument xml , string filePath)
        {
            try
            {
                xml.Save(filePath);
                return true;
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
                return false;
            }
        }

 

If the display style does not require configuration file, you can

using (XmlTextWriter xtw = new XmlTextWriter(file, null))  
{  
    xtw.Formatting = Formatting.None;  
    XmlDoc.Save(xtw);  
}

 

Achieved, but this will cause all nodes xml sequentially arranged, the structure does not appear as nodes

If there is necessary to maintain the structure, but also empty node xml file does not produce wrap, you can assign when an empty node, giving

A space.

if (yAxisModelList[no - 1].Title.ToString().Equals("") || yAxisModelList[no - 1].Title == null)
                {
                    xmlNode.SelectSingleNode("title").InnerText = " ";
                    xmlNode.SelectSingleNode("titleKey").InnerText = " ";
                }
                else
                {
                    xmlNode.SelectSingleNode("title").Inner Text = yAxisModelList [no - 1].Title;
                    xmlNode.SelectSingleNode("titleKey").InnerText = yAxisModelList[no - 1].TitleKey;
                }
