Write XML to file

Posted Date: 10 Nov 2009 |Updated: 10-Nov-2009 |Category: XML |Author: |Member Level: Gold |Points: 5 |

This code snippet is related to xml serialization. In many cases, we need to write serialized object into XML.

Following code shows how to write object into XML. 


using (StreamWriter writer = new StreamWriter(FileName, false))
{  
   writer.Write(reportDescriptor.ToString());                      
}


In above code reportDescriptor is a object of ReportDescriptor class.

Following code converts xml into string. As well as write xml by encoding UTF-8.

public override string ToString()
{
            string sdata = string.Empty;
            XmlSerializer x = new XmlSerializer(this.GetType());
            XmlWriterSettings xwSettings = new XmlWriterSettings();
            xwSettings.Encoding = Encoding.UTF8;
            xwSettings.Indent = true;
            xwSettings.IndentChars = "\t";
            xwSettings.NewLineChars = Environment.NewLine;
            xwSettings.ConformanceLevel = ConformanceLevel.Document;

            using (MemoryStream stream = new MemoryStream())
            {
                using (XmlWriter xw = XmlTextWriter.Create(stream, xwSettings))
                {
                    x.Serialize(xw, this);
                    sdata = Encoding.UTF8.GetString(stream.ToArray());
                    if (sdata.Length > 0 && sdata[0] != '<')
                        sdata = sdata.Substring(1, sdata.Length - 1);

                }

            }
            return sdata;
}

You can use it as below 

var xmlString = SerializationUtil.ToXml(obj);
var obj = SerializationUtil.FromXml(xmlString);

public static class Serialize
{
    private static readonly Dictionary _serializersCache = new Dictionary();

    private static XmlSerializer GetSerializer(Type type)
    {
        XmlSerializer xmls;
        if (!_serializersCache.TryGetValue(type, out xmls))
        {
            xmls = new XmlSerializer(type);
            _serializersCache[type] = xmls;
        }
        return xmls;
    }

    public static string ToXml(T obj)
    {
        var xmls = GetSerializer(typeof(T));
        var Strbuild = new StringBuilder();
        using (var writer = new StringWriter(Strbuild))
        {
            xmls.Serialize(writer, obj);
            writer.Close();
        }
        return Strbuild.ToString();
    }
    public static T FromXml(string xml)
    {
        T a;
        var xmls = GetSerializer(typeof(T));
        using (var reader = new StringReader(xml))
        {
            a = (T)xmls.Deserialize(reader);
            reader.Close();
        }
        return a;
    }
