Type.IsPrimitiveImpl メソッド

派生クラスによってオーバーライドされるときに、IsPrimitive プロパティを実装し、Type がプリミティブ型の 1 つかどうかを判断します。

名前空間: System
アセンブリ: mscorlib (mscorlib.dll 内)
構文

Visual Basic (宣言)

Protected MustOverride Function
 IsPrimitiveImpl As Boolean

Visual Basic (使用法)

Dim returnValue As Boolean

returnValue = Me.IsPrimitiveImpl

protected abstract bool IsPrimitiveImpl ()

C++

protected:
virtual bool IsPrimitiveImpl () abstract

protected abstract boolean IsPrimitiveImpl ()

JScript

protected abstract function IsPrimitiveImpl
 () : boolean

戻り値
Type がプリミティブ型の 1 つである場合は true。それ以外の場合は false。

解説

プリミティブ型には、Boolean、Byte、SByte、Int16、UInt16、Int32、UInt32、Int64、UInt64、Char、Double、および Single があります。

使用例

指定された型がプリミティブ型かどうかを判断して結果を表示する例を次に示します。
