傳回

如果應該呼叫 GetStandardValues() 以尋找物件支援的通用值集合,則為 true,否則為 falsetrue if GetStandardValues() should be called to find a common set of values the object supports; otherwise, false.

GetStandardValuesSupported(ITypeDescriptorContext)

會使用指定的內容傳回,這個物件是否支援可從清單中挑選的標準值集合。Returns whether this object supports a standard set of values that can be picked from a list, using the specified context.

public:
 virtual bool GetStandardValuesSupported(System::ComponentModel::ITypeDescriptorContext ^ context);
public virtual bool GetStandardValuesSupported (System.ComponentModel.ITypeDescriptorContext context);
abstract member GetStandardValuesSupported : System.ComponentModel.ITypeDescriptorContext -> bool
override this.GetStandardValuesSupported : System.ComponentModel.ITypeDescriptorContext -> bool
Public Overridable Function GetStandardValuesSupported (context As ITypeDescriptorContext) As Boolean

傳回

如果應該呼叫 GetStandardValues() 以尋找物件支援的通用值集合,則為 true,否則為 falsetrue if GetStandardValues() should be called to find a common set of values the object supports; otherwise, false.

備註

在這個類別中實作時,這個方法永遠傳回 falseAs implemented in this class, this method always returns false.

context 參數可以用於擷取環境的其他資訊,而這個轉換子就是從該環境叫用的。Use the context parameter to extract additional information about the environment from which this converter is invoked. 這個參數可以是null, 所以請一律檢查它。This parameter can be null, so always check it. 甚至,內容物件上的屬性可能會傳回 nullAlso, properties on the context object can return null.

給繼承者的注意事項

如果您想要轉換的類型支援標準值, 請覆寫這個方法。Override this method if the type you want to convert supports standard values.
