[TestMethod()]
public void SerializeTest()

Assert.AreEqual<string>(_expect, _actual);
}
[TestMethod()]
public void DeserializeTest()
{

string _jsonString = "[{'Name':'YanZhiweiA','Age':10,'Address':'shanghaiA'},{'Name':'YanZhiweiB','Age':11,'Address':'shanghaiB'}]";
List<Person> _result = (List<Person>)ScriptSerializerHelper.Deserialize<Person>(_jsonString);
bool _actual = _expected.SequenceEqual(_result, new PersonCompare());
Assert.IsTrue(_actual);

{
public bool Equals(Person x, Person y)
{
return (x.Age == y.Age) && (x.Address == y.Address) && (x.Name == y.Name);
}
public int GetHashCode(Person obj)
{
return obj.Name.GetHashCode();
