MergablePropertyAttribute.AllowMerge 屬性

定義

命名空間:

System.ComponentModel

組件:

System.ComponentModel.Primitives.dll

來源:

MergablePropertyAttribute.cs

取得值，表示這個屬性是否可在 [屬性] 視窗中結合其他物件的屬性。

public:
 property bool AllowMerge { bool get(); };

public bool AllowMerge { get; }

member this.AllowMerge : bool

Public ReadOnly Property AllowMerge As Boolean

屬性值

Boolean

如果這個屬性可以在 [屬性] 視窗中結合其他物件的屬性，則為 true，否則為 false。

範例

下列範例會檢查是否 MyProperty 適合合併。 首先，程式代碼會藉由下列方式 MyProperty 取得 的屬性：

• PropertyDescriptorCollection擷取具有 物件之所有屬性的 。

• 索引至 PropertyDescriptorCollection 以取得 MyProperty。

• 將此屬性的屬性儲存在屬性變數中。

然後程式代碼會將 設定myAttribute為中的 AttributeCollection 值MergablePropertyAttribute，並檢查 屬性是否適合合併。

// Gets the attributes for the property.
AttributeCollection^ attributes = TypeDescriptor::GetProperties( this )[ "MyPropertyProperty" ]->Attributes;

// Checks to see if the property is bindable.
MergablePropertyAttribute^ myAttribute = dynamic_cast<MergablePropertyAttribute^>(attributes[ MergablePropertyAttribute::typeid ]);
if ( myAttribute->AllowMerge )
{
   // Insert code here.
}

// Gets the attributes for the property.
AttributeCollection attributes = 
   TypeDescriptor.GetProperties(this)["MyPropertyProperty"].Attributes;

// Checks to see if the property is bindable.
MergablePropertyAttribute myAttribute = (MergablePropertyAttribute)attributes[typeof(MergablePropertyAttribute)];
if(myAttribute.AllowMerge) {
   // Insert code here.
}

' Gets the attributes for the property.
Dim attributes As AttributeCollection = _
   TypeDescriptor.GetProperties(Me)("MyPropertyProperty").Attributes
       
' Checks to see if the property is bindable.
Dim myAttribute As MergablePropertyAttribute = _
   CType(attributes(GetType(MergablePropertyAttribute)), _
   MergablePropertyAttribute)
If myAttribute.AllowMerge Then
    ' Insert code here.
End If
