1.詞匯

• dynamic type 動(dòng)態(tài)類型
• implicitly 隱式的

2.例句

• Dynamic type is that the C# compiler allows you to use dynamically. If an expression is of type dynamic, you can call methods on it, access properties, pass it around as a method argument, and so on—and most of the normal binding process happens at execution time instead of compile time. You can implicitly convert a value from dynamic to any other type.

  C#編譯器允許動(dòng)態(tài)使用該類型，如果一個(gè)表達(dá)式為動(dòng)態(tài)類型，你可以調(diào)用它的方法，訪問它的屬性，把其作為參數(shù)等等，大多數(shù)的綁定發(fā)生在執(zhí)行時(shí)而不是編譯時(shí)，你也可以隱式的把動(dòng)態(tài)類型轉(zhuǎn)換為任意其它類型。

• This behavior can also be useful even within pure C# code, with no interop involved, but it’s fun to see it working with other languages.

  即使在純粹的C#代碼中，雖然不需要與com對象交互，但可能與與其他語言交互，這樣的行為也是十分有意義的。

3.代碼

• 下面的代碼展示的是，嵌入的ironpython腳本，使用dynamic操作

ScriptEngine engine = Python.CreateEngine();
ScriptScope scope = engine.ExecuteFile("FindProducts.py");
dynamic products = scope.GetVariable("products");
foreach (dynamic product in products)
{
   Console.WriteLine("{0}: {1}", product.ProductName, product.Price);
}
