Type.FullName プロパティ

定義

型の完全修飾名を取得します。その名前空間を含みますが、アセンブリは含みません。Gets the fully qualified name of the type, including its namespace but not its assembly.

public:
 abstract property System::String ^ FullName { System::String ^ get(); };
public abstract string FullName { get; }
member this.FullName : string
Public MustOverride ReadOnly Property FullName As String

プロパティ値

型の完全修飾名で、名前空間を含むが、アセンブリは含まないもの。現在のインスタンスが、ジェネリック型パラメーター、配列型、ポインター型、または型パラメーターに基づくnull 型、またはジェネリック型定義ではないが未解決の型パラメーターを含むジェネリック型を表す場合は、byrefThe fully qualified name of the type, including its namespace but not its assembly; or null if the current instance represents a generic type parameter, an array type, pointer type, or byref type based on a type parameter, or a generic type that is not a generic type definition but contains unresolved type parameters.

実装

次の例では、指定された型の完全な名前を表示します。The following example displays the full name of the specified type.

using namespace System;
int main()
{
   Type^ t = Array::typeid;
   Console::WriteLine( "The full name of the Array type is {0}.", t->FullName );
}

/* This example produces the following output:

The full name of the Array type is System.Array.
 */
using System;
class TestFullName 
{
public static void Main() 
    {
    Type t = typeof(Array);
    Console.WriteLine("The full name of the Array type is {0}.", t.FullName);
    }
} 

/* This example produces the following output:

The full name of the Array type is System.Array.
 */
Class TestFullName
   
    Public Shared Sub Main()
        Dim t As Type = GetType(Array)
        Console.WriteLine("The full name of the Array type is {0}.", t.FullName)
    End Sub
End Class

' This example produces the following output:
'
'The full name of the Array type is System.Array.
'

次の例では、ToString メソッドによって返される文字列と、NameFullName、および AssemblyQualifiedName プロパティを比較します。The following example compares the strings returned by the ToString method and the Name, FullName, and AssemblyQualifiedName properties.

        ShowTypeInfo(t);

        var list = new List<String>();
        t = list.GetType();
        ShowTypeInfo(t);

        Object v = 12;
        t = v.GetType();
        ShowTypeInfo(t);

        t = typeof(IFormatProvider);

        IFormatProvider ifmt = NumberFormatInfo.CurrentInfo;
        t = ifmt.GetType();

注釈

たとえば、String の種類の完全修飾名は System.Stringです。For example, the fully qualified name of the String type is System.String. これは、完全な名前と完全なアセンブリ名で構成される、AssemblyQualifiedName プロパティによって返されるアセンブリ修飾名と比較します。Contrast this with the assembly-qualified name returned by the AssemblyQualifiedName property, which consists of the full name plus the full assembly name.

現在の型がクローズジェネリック型を表している場合、ジェネリック型自体の文字列表現が完全なアセンブリによって修飾されていなくても、FullName プロパティによって返される文字列の型引数は完全なアセンブリ名によって修飾されます。指定.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の FullName プロパティと、クローズジェネリック型を表す型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.

   public static void Main()
   {
      Type t = typeof(List<>);

このプロパティは、次の場合に null を返します。This property returns null if:

  • 現在の Type オブジェクトは、ジェネリック型の型パラメーターを表します。The current Type object represents a type parameter of a generic type.

    次の例では、Nullable<T> 型の型パラメーターを取得し、その FullName プロパティを表示しようとしています。The following example retrieves the type parameter of the Nullable<T> type and attempts to display its FullName property.

             Type[] gtArgs = t.GetGenericArguments();
             for (int ctr = 0; ctr < gtArgs.Length; ctr++) {

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

    次の例では、型 T の配列に渡される3つの Display(T[])メソッドを使用して、Generictype1<T>のジェネリック型を定義しています。HandleT(T)。 T オブジェクトが渡されます。および ChangeValue(ref T)。参照渡しで T オブジェクトを渡します。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. とC# Visual Basic では、HandleT メソッドのポインターとして T を定義することはできないため、ジェネリック型へのポインターを作成するには、メソッドのパラメーター型を表す Type オブジェクトで MakePointerType メソッドを呼び出す必要があります。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. この例の出力は、3つのすべてのケースで、FullName プロパティが nullであることを示しています。The output from the example shows that in all three cases, the FullName property is null.

    using System.Reflection;

    ' 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
    

    nullない FullName を取得するには、例に示すように、GetGenericTypeDefinition メソッドを使用してジェネリック型定義を取得します。To get a FullName that is not null, you can use the GetGenericTypeDefinition method to get the generic type definition, as the example illustrates.
