Type.IsPrimitive Type.IsPrimitive Type.IsPrimitive Type.IsPrimitive Property

定義

取得值,指出 Type 是否為其中一個基本類型 (Primitive Type)。Gets a value indicating whether the Type is one of the primitive types.

public:
 property bool IsPrimitive { bool get(); };
public bool IsPrimitive { get; }
member this.IsPrimitive : bool
Public ReadOnly Property IsPrimitive As Boolean

屬性值

如果 true 是其中一個基本類型,則為 Type,否則為 falsetrue if the Type is one of the primitive types; otherwise, false.

範例

下列範例示範IsContextful Type類別的、 IsMarshalByRefIsPrimitive屬性。The following example demonstrates the IsContextful, IsMarshalByRef, and IsPrimitive properties of the Type class. 它會檢查指定的類型是否可以裝載于內容中、是否可以透過傳址方式封送處理, 以及該類型是否為基本資料類型。It checks whether the given type can be hosted in the context, whether it can be marshaled by reference, and whether the type is a primitive data type.

備註

基本類型Boolean為、 Int16 、、、UInt16Int32 、、Int64、、 、、、UInt64 UInt32 IntPtr SByte Byte UIntPtr CharDouble、和SingleThe primitive types are Boolean, Byte, SByte, Int16, UInt16, Int32, UInt32, Int64, UInt64, IntPtr, UIntPtr, Char, Double, and Single.

如果目前Type的表示泛型型別, 或泛型型別或泛型方法定義中的類型參數, 則這個屬性false一律會傳回。If the current Type represents a generic type, or a type parameter in the definition of a generic type or generic method, this property always returns false.
