例
次の例は、プロパティとプロパティ、およびのメソッドの使用方法を示して Namespace Module ToString Type います。
using namespace System;
namespace MyNamespace
{
ref class MyClass
{
};
}
void main()
{
Type^ myType = MyNamespace::MyClass::typeid;
Console::WriteLine("Displaying information about {0}:", myType );
// Get the namespace of the class MyClass.
Console::WriteLine(" Namespace: {0}", myType->Namespace );
// Get the name of the module.
Console::WriteLine(" Module: {0}", myType->Module );
// Get the fully qualified common language runtime namespace.
Console::WriteLine(" Fully qualified type: {0}", myType );
}
// The example displays the following output:
// Displaying information about MyNamespace.MyClass:
// Namespace: MyNamespace
// Module: type_tostring.exe
// Fully qualified name: MyNamespace.MyClass
using System;
namespace MyNamespace
{
class MyClass
{
}
}
public class Example
{
public static void Main()
{
Type myType = typeof(MyNamespace.MyClass);
Console.WriteLine("Displaying information about {0}:", myType);
// Get the namespace of the myClass class.
Console.WriteLine(" Namespace: {0}.", myType.Namespace);
// Get the name of the module.
Console.WriteLine(" Module: {0}.", myType.Module);
// Get the fully qualified type name.
Console.WriteLine(" Fully qualified name: {0}.", myType.ToString());
}
}
// The example displays the following output:
// Displaying information about MyNamespace.MyClass:
// Namespace: MyNamespace.
// Module: type_tostring.exe.
// Fully qualified name: MyNamespace.MyClass.
Namespace MyNamespace
Class [MyClass]
End Class
End Namespace
Public Class Example
Public Shared Sub Main()
Dim myType As Type = GetType(MyNamespace.MyClass)
Console.WriteLine(", myType)
' Get the namespace of the MyClass class.
Console.WriteLine(" Namespace: {0}.", myType.Namespace)
' Get the name of the module.
Console.WriteLine(" Module: {0}.", myType.Module)
' Get the fully qualified type name.
Console.WriteLine(" Fully qualified name: {0}.", myType.ToString())
End Sub
End Class
' The example displays the following output:
' Displaying information about MyNamespace.MyClass:
' Namespace: MyNamespace.
' Module: type_tostring.exe.
' Fully qualified name: MyNamespace.MyClass.

注釈
このメソッドは、すべてのプリミティブ型の完全修飾共通言語ランタイム名前空間と名前を返します。 たとえば、C# 命令では、 (long)0.Type().ToString() 単に "int64" ではなく "system.string" が返されます。
現在のが Type ジェネリック型を表している場合、型とその型引数は、名前空間と入れ子になった型によって修飾されますが、アセンブリによって修飾されることはありません。 現在のが Type ジェネリック型またはジェネリックメソッドの定義の型パラメーターを表している場合、このメソッドは型パラメーターの非修飾名を返します。
