DesignerSerializationVisibilityAttribute.Visibility 屬性

定義

命名空間:

System.ComponentModel

組件:

System.ComponentModel.Primitives.dll

來源:

DesignerSerializationVisibilityAttribute.cs

在決定是否要或是如何保存屬性的值時，取得代表序列化程式所應使用基本序列化模式的值。

public:
 property System::ComponentModel::DesignerSerializationVisibility Visibility { System::ComponentModel::DesignerSerializationVisibility get(); };

public System.ComponentModel.DesignerSerializationVisibility Visibility { get; }

member this.Visibility : System.ComponentModel.DesignerSerializationVisibility

Public ReadOnly Property Visibility As DesignerSerializationVisibility

屬性值

DesignerSerializationVisibility

其中一個 DesignerSerializationVisibility 值。 預設值為 Visible。

範例

下列程式代碼範例示範如何檢查 DesignerSerializationVisibilityAttribute 的值 MyProperty。 首先，程式代碼會取得 PropertyDescriptorCollection 具有物件之所有屬性的 。 接下來，程式代碼會索引到 PropertyDescriptorCollection ，以取得 MyProperty。 然後，程式代碼會傳回此屬性的屬性，並將其儲存在屬性變數中。

此範例提供兩種不同的方法來檢查的值 DesignerSerializationVisibilityAttribute。 在第二個static代碼段中，此範例會使用 值呼叫 Equals 方法。 在最後一個代碼段中，此範例會使用 Visibility 屬性來檢查值。

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

// Checks to see if the value of the DesignerSerializationVisibilityAttribute is set to Content.
if ( attributes[ DesignerSerializationVisibilityAttribute::typeid ]->Equals( DesignerSerializationVisibilityAttribute::Content ) )
{
   // Insert code here.
}


// This is another way to see whether the property is marked as serializing content.
DesignerSerializationVisibilityAttribute^ myAttribute = dynamic_cast<DesignerSerializationVisibilityAttribute^>(attributes[ DesignerSerializationVisibilityAttribute::typeid ]);
if ( myAttribute->Visibility == DesignerSerializationVisibility::Content )
{
   // Insert code here.
}

// Gets the attributes for the property.
 AttributeCollection attributes = 
    TypeDescriptor.GetProperties(this)["MyProperty"].Attributes;
 
 // Checks to see if the value of the DesignerSerializationVisibilityAttribute is set to Content.
 if(attributes[typeof(DesignerSerializationVisibilityAttribute)].Equals(DesignerSerializationVisibilityAttribute.Content)) {
    // Insert code here.
 }
 
 // This is another way to see whether the property is marked as serializing content.
 DesignerSerializationVisibilityAttribute myAttribute = 
    (DesignerSerializationVisibilityAttribute)attributes[typeof(DesignerSerializationVisibilityAttribute)];
 if(myAttribute.Visibility == DesignerSerializationVisibility.Content) {
    // Insert code here.
 }

' Gets the attributes for the property.
Dim attributes As AttributeCollection = _
    TypeDescriptor.GetProperties(Me)("MyProperty").Attributes

' Checks to see if the value of the DesignerSerializationVisibilityAttribute
' is set to Content.
If attributes(GetType(DesignerSerializationVisibilityAttribute)).Equals( _
    DesignerSerializationVisibilityAttribute.Content) Then
    ' Insert code here.
End If 

' This is another way to see whether the property is marked as serializing content.
Dim myAttribute As DesignerSerializationVisibilityAttribute = _
    CType(attributes(GetType(DesignerSerializationVisibilityAttribute)), _
    DesignerSerializationVisibilityAttribute)
If myAttribute.Visibility = DesignerSerializationVisibility.Content Then
    ' Insert code here.
End If
