注釈

たとえば、完全修飾名のString型はSystem.Stringします。For example, the fully qualified name of the String type is System.String. これによって返されるアセンブリ修飾名に対し、AssemblyQualifiedNameプロパティで、完全な名前と完全なアセンブリ名で構成されます。Contrast this with the assembly-qualified name returned by the AssemblyQualifiedName property, which consists of the full name plus the full assembly name.

文字列の型引数がによって返される現在の型はクローズ ジェネリック型を表している場合、FullNameプロパティは、その完全では、ジェネリック型パラメーター自体の文字列表現は修飾されていない場合でも、アセンブリの完全な名前によって修飾されますアセンブリ名。If the current type represents a closed generic type, the type arguments in the string returned by the FullName property are qualified by their full assembly name, even though the string representation of the generic type itself is not qualified by its full assembly name. 次の例は、ジェネリック型定義を表す型とクローズ ジェネリック型を表す 1 つの FullName プロパティの違いを示しています。The following example illustrates the difference in the FullName property for a type that represents generic type definition and one that represents a closed generic type.

  • 現在Typeオブジェクトは、ポインター型、配列型を表しますまたはbyrefジェネリック型パラメーターに基づいている型。The current Type object represents an array type, a pointer type, or a byref type that is based on a generic type parameter.

    次の例は、ジェネリック型を定義Generictype1<T>、3 つのメソッド: Display(T[])T 型の配列に渡しますHandleT(T)、T は渡されるとChangeValue(ref T)T のオブジェクト参照によって渡されます。The following example defines a generic type, Generictype1<T>, with three methods: Display(T[]), which is passed an array of type T; HandleT(T), which is passed a T object; and ChangeValue(ref T), which is passed a T object by reference. C# および Visual Basic が内のポインターとして T を定義することに許可されないため、HandleTを呼び出すメソッドがある、MakePointerTypeメソッドをTypeジェネリック型へのポインターを作成するメソッドのパラメーターの型を表すオブジェクト。Because C# and Visual Basic do not allow us to define T as a pointer in the HandleT method, we have to call the MakePointerType method on the Type object that represents the method's parameter type to create a pointer to a generic type. 例の出力は 3 つのすべてのケースで、FullNameプロパティはnullします。The output from the example shows that in all three cases, the FullName property is null.

    ' The example displays the following output:
    '       Generic Class: Derived`1
    '          Contains Generic Paramters: True
    '          Generic Type Definition: True
    '       
    '       Its Base Class: (unassigned) Base`1[T]
    '          Contains Generic Paramters: True
    '          Generic Type Definition: False
    '          Full Name: Base`1
    '       
    '       Generic Class: Base`1
    '          Contains Generic Paramters: True
    '          Generic Type Definition: True
    

    取得する、FullNameでないnull、使用することができます、GetGenericTypeDefinition例に示すように、ジェネリック型定義を取得するメソッド。To get a FullName that is not null, you can use the GetGenericTypeDefinition method to get the generic type definition, as the example illustrates.
