型の配列から作成された、XmlSerializer オブジェクトの配列を返します。
public:
static cli::array <System::Xml::Serialization::XmlSerializer ^> ^ FromTypes(cli::array <Type ^> ^ types);public static System.Xml.Serialization.XmlSerializer[] FromTypes (Type[] types);public static System.Xml.Serialization.XmlSerializer[] FromTypes (Type[]? types);static member FromTypes : Type[] -> System.Xml.Serialization.XmlSerializer[]Public Shared Function FromTypes (types As Type()) As XmlSerializer()パラメーター
戻り値
XmlSerializer オブジェクトの配列。
例
次の例では、メソッドを FromTypes 使用してオブジェクトの XmlSerializer 配列を返します。 このコードには、オブジェクトの配列 Type を作成するためにそれぞれ使用される 3 つのクラス定義が含まれています。

注釈
このFromTypesメソッドを使用すると、オブジェクトの配列を処理するためのオブジェクトのXmlSerializerType配列を効率的に作成できます。 ただし、このメソッドを繰り返し呼び出す場合は、呼び出し元が返されたシリアライザーをキャッシュすることをお勧めします。
