本文实例讲述了C#写入对象或集合类型数据到xml文件的方法。分享给大家供大家参考。具体实现方法如下：

public static string SerializeToXmlString(object objectToSerialize) {
  MemoryStream memoryStream = new MemoryStream();
  System.Xml.Serialization.XmlSerializer xmlSerializer = new System.Xml.Serialization.XmlSerializer(objectToSerialize.GetType());
  xmlSerializer.Serialize(memoryStream, objectToSerialize);
  ASCIIEncoding ascii = new ASCIIEncoding();
  return ascii.GetString(memoryStream.ToArray());
}

希望本文所述对大家的C#程序设计有所帮助。
