xml序列化、反序列化
//xml序列化
public static string Seria(DataSet ds)
{
XmlSerializer serializer = new XmlSerializer(typeof(DataSet));
StringBuilder sb = new StringBuilder();
XmlWriter writer = XmlWriter.Create(sb);
serializer.Serialize(writer, ds);
return sb.ToString();
}
//xml反序列化
public static DataSet DeSeria(string sb)
{
XmlSerializer serializer = new XmlSerializer(typeof(DataSet));
StringReader sr = new StringReader(sb);
XmlReader xr = XmlReader.Create(sr);
DataSet ds = (DataSet)serializer.Deserialize(xr);
return ds;
}
public static string Seria<T>(T ds)
{
XmlSerializer serializer = new XmlSerializer(typeof(T));
StringBuilder sb = new StringBuilder();
XmlWriter writer = XmlWriter.Create(sb);
serializer.Serialize(writer, ds);
return sb.ToString();
}
//xml反序列化
public static T DeSeria<T>(string sb)
{
XmlSerializer serializer = new XmlSerializer(typeof(T));
StringReader sr = new StringReader(sb);
XmlReader xr = XmlReader.Create(sr);
T ds = (T)serializer.Deserialize(xr);
return ds;
