PropertyTabAttribute 构造函数

定义

初始化 PropertyTabAttribute 类的新实例。

重载

PropertyTabAttribute()

初始化 PropertyTabAttribute 类的新实例。

PropertyTabAttribute(String)

PropertyTabAttribute(Type)

使用指定的选项卡类型初始化 PropertyTabAttribute 类的新实例。

PropertyTabAttribute(String, PropertyTabScope)

使用指定的选项卡类名和选项卡范围初始化 PropertyTabAttribute 类的新实例。

PropertyTabAttribute.cs
Source:
PropertyTabAttribute.cs
Source:
PropertyTabAttribute.cs

初始化 PropertyTabAttribute 类的新实例。

public:
 PropertyTabAttribute();
public PropertyTabAttribute ();
Public Sub New ()

注解

这是一个无参数构造函数,用于创建未初始化的 PropertyTabAttribute。 此构造函数可用于从此属性派生,并通过调用 InitializeArrays指定多个选项卡类型。
