属性值

如果该属性可以与“属性”窗口中属于其他对象的属性进行组合，则为 true；否则为 false。

示例

以下示例检查是否 MyProperty 适合合并。 首先，代码通过以下方式获取 的属性 MyProperty ：

• 检索 PropertyDescriptorCollection 具有 对象的所有属性的 。

• 索引到 中 PropertyDescriptorCollection 以获取 MyProperty。

• 将此属性的属性保存在 attributes 变量中。

然后，代码将 设置为 myAttribute 中 AttributeCollection 的值MergablePropertyAttribute，并检查 属性是否适合合并。

// 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
