如何使用反射对序列类型进行XML序列化？

Question

I'm trying to XML serialize a class after getting the class through reflection. Can anyone suggest me the exact method. Below is my code.

Assembly myassembly = Assembly.LoadFile(myassemblypath);
List<Type> types = myassembly .GetTypes().Where(x => x.BaseType == typeof(myType));
foreach (Type item in types)
{
 dynamic instance = Activator.CreateInstance(item);
 using (var writer = new StringWriter())
{
 new XmlSerializer(item.GetType()).Serialize(writer, instance);
string xmlEncodedList = writer.GetStringBuilder().ToString();
Console.WriteLine(xmlEncodedList);
 }
}

This code is not working, it gives me exception.

Answer 1

as you are getting system.RuntimeType exception , for getting actual type you need to unwrap actual type from RuntimeType , that will resolve your issue.

following is code to unwrape actual type

 var runTimeObj = Activator.
               CreateInstance(assemblyName, assemblyName + "." + className);
 //T is generic type as i m using genric
 //but point of interest here is unwrap method to get actual type
 var dataProvider = (T)runTimeObj.Unwrap();

one more example

  ObjectHandle handle = Activator.CreateInstance("PersonInfo", "Person");
  Object p = handle.Unwrap();
  Type t = p.GetType();

one more problem with you code use of dynamic dont use it make use of ObjectHandle ...as given in example

for unwrap check : https://msdn.microsoft.com/en-us/library/d133hta4%28v=vs.110%29.aspx
