FieldInfo.FieldType プロパティ

このフィールド オブジェクトの型を取得します。

Public MustOverride ReadOnly Property FieldType As Type
[C#]
public abstract Type FieldType {get;}
[C++]
public: __property virtual Type* get_FieldType() = 0;
[JScript]
public abstract function get FieldType() : Type;

プロパティ値

このフィールド オブジェクトの型。

解説

Type は、String、 Boolean 、GUID などのプリミティブ データ型です。

FieldType プロパティを取得するには、最初に Type クラスを取得します。そして、その Type から FieldInfo を取得します。最後に、 FieldInfo から FieldType を取得します。

使用例

フィールドを作成し、その型と FieldInfo を取得して FieldType を表示する例を次に示します。

 

Imports System
Imports System.Reflection

' Make a field.
Public Class Myfield
    Private SomeField As String = "private field"
    Public ReadOnly Property Field() As String
        Get
            Return SomeField
        End Get
    End Property
End Class 'Myfield

Public Class Myfieldinfo

    Public Shared Function Main() As Integer
        Console.WriteLine("Reflection.FieldInfo")
        Console.WriteLine()
        Dim Myfield As New Myfield()

        ' Get the type and FieldInfo.
        Dim MyType As Type = Type.GetType("Myfield")
        Dim Myfieldinfo As FieldInfo = MyType.GetField("SomeField", BindingFlags.Instance Or BindingFlags.NonPublic)

        ' Get and display the FieldType.
        Console.WriteLine("{0}.{1} - {2};", MyType.FullName, Myfieldinfo.Name, Myfield.Field)
        'Console.WriteLine("{0} - ", Myfieldinfo.Name)
