AttributeCollection.Count 属性

定义

命名空间:

System.ComponentModel

程序集:

netstandard.dll, System.ComponentModel.TypeConverter.dll

Source:

AttributeCollection.cs

获取属性数。

public:
 property int Count { int get(); };

public int Count { get; }

member this.Count : int

Public ReadOnly Property Count As Integer

属性值

Int32

属性数。

示例

下面的代码示例使用 Count 属性打印文本框中的属性 button1 数。 它假定 button1 已在 textBox1 窗体上创建。

private:
   void GetCount()
   {
      // Creates a new collection and assigns it the attributes for button1.
      AttributeCollection^ attributes;
      attributes = TypeDescriptor::GetAttributes( button1 );
      
      // Prints the number of items in the collection.
      textBox1->Text = attributes->Count.ToString();
   }

void GetCount()
{
    // Creates a new collection and assigns it the attributes for button1.
    AttributeCollection attributes;
    attributes = TypeDescriptor.GetAttributes(button1);

    // Prints the number of items in the collection.
    textBox1.Text = attributes.Count.ToString();
}

Private Sub GetCount
    ' Creates a new collection and assigns it the attributes for button 1.
    Dim attributes As AttributeCollection
    attributes = TypeDescriptor.GetAttributes(button1)
    ' Prints the number of items in the collection.
    textBox1.Text = attributes.Count.ToString
End Sub

注解

可以使用该 Count 属性设置循环访问对象集合的限制。 如果集合从零开始，请确保用作 Count - 1 循环的上限。
