EditableAttribute 類別
定義
表示是否可以編輯資料欄位。Indicates whether a data field is editable.
public ref class EditableAttribute sealed : Attribute[System.AttributeUsage(System.AttributeTargets.Field | System.AttributeTargets.Property, AllowMultiple=false, Inherited=true)]
public sealed class EditableAttribute : Attribute[<System.AttributeUsage(System.AttributeTargets.Field | System.AttributeTargets.Property, AllowMultiple=false, Inherited=true)>]

備註
當 EditableAttribute 資料欄位上的屬性存在時，會指出使用者是否應該能夠變更欄位的值。The presence of the EditableAttribute attribute on a data field indicates whether the user should be able to change the field's value.
這個類別不會強制執行，也不保證欄位是可編輯的。This class neither enforces nor guarantees that a field is editable. 無論這個屬性的存在與否，基礎資料存放區都可以讓欄位變更。The underlying data store might allow the field to be changed regardless of the presence of this attribute.

| GetType() |
取得目前執行個體的 Type。Gets the Type of the current instance. (繼承來源 Object) |
| IsDefaultAttribute() |
在衍生類別中覆寫時，表示這個執行個體的值是衍生類別的預設值。When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (繼承來源 Attribute) |
| Match(Object) |
在衍生類別中覆寫時，會傳回值，表示這個執行個體是否等於指定物件。When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (繼承來源 Attribute) |
