Dynamic Object to Native Object

Dynamic objects in runtime can be converted to native.

Note: requires DB with established connection

public void DynamicToNative ()

{

DB db = null;

try

{

const string db_name = "DynamicToNativeTest";

db = new DB("server=(local);password=;options=none;");

db.DeleteDatabase(db_name, true);

db.CreateDatabase(db_name);

db.OpenDatabase(db_name);

Book book = new Book()

{

DbID = 12345,

Edition = -33,

Price = 776.32F,

IBSN = "7748-3782-38768-23343",

Publisher = "Publisher Mublisher",

Title = "Title Mitle",

YearPublished = new DateTime(356, 2, 2),

Parent = new ParentBook() { Publisher = "Co"}

};

Dynamic dynObj = new Dynamic(book);

db.Store(dynObj);

Book newBook = dynObj.ToNative<Book>();

Assert.AreEqual(newBook.DbID, (long)dynObj["DbID"]);

Assert.AreEqual(newBook.Edition, (int)dynObj["Edition"]);

Assert.AreEqual(newBook.Price, (float)dynObj["Price"]);

Assert.AreEqual(newBook.IBSN, (string)dynObj["IBSN"]);

Assert.AreEqual(newBook.Publisher, (string)dynObj["Publisher"]);

Assert.AreEqual(newBook.Title, (string)dynObj["Title"]);

Assert.AreEqual(newBook.YearPublished, (DateTime)dynObj["YearPublished"]);

Assert.AreEqual(newBook.Parent.Publisher, (string)dynObj["Parent"]["Publisher"]);

}

finally { db.Close(); }

}

Update existing native object

To update existing native object ToNative method can be used. The following example demonstrates this

var @do = new Dynamic();

@do["Name"] = "Frank";

db.Store(@do);

//get object back

@do = db.Query<Dynamic>().Where(x => x["Name"] == "Frank").First();

//update existing native object “user”

@do.ToNative<MyUser>(user);
