只写属性或方法？ [英] WriteOnly Property or Method?

问题描述

有一个特定的场景，一个只写属性使更多的意义则方法？该方法的方法感觉对我来说更自然。

Is there a particular scenario where a WriteOnly property makes more sense then a method? The method approach feels much more natural to me.

什么是正确的做法？

使用属性

Public WriteOnly Property MyProperty As String
   Set(ByVal value as String)
      m_myField = value
   End Set
End Property

public string MyProperty
{
   set{ m_myField = value;}
}

使用方法：

Public Sub SetMyProperty(ByVal value as String)
   m_myField = value
End Sub

public void SetMyProperty(string value)
{
   m_myField = value;
}

修改 只是为了澄清我指的是只写属性。

EDIT Just to clarify I am referring to "WriteOnly" properties.

推荐答案

我觉得一个属性指示的东西，可以是只读或读/写。只写属性的行为并不明显，所以我避免造成他们。

I think a property indicates something that can be read-only or read/write. The behaviour of a write-only property is not obvious so I avoid creating them.

作为一个例子，设定值的列表中的一个视图下拉和访问所选择的项目：

As an example, setting a list of values in a drop-down on a view and accessing the selected item:

public interface IWidgetSelector
{
  void SetAvailableWidgets(string[] widgets);

  string SelectedWidget { get; set; }
}

更有意义比：

Makes more sense than:

public interface IWidgetSelector
{
  string[] AvailableWidgets { set; }

  string SelectedWidget { get; set; }
}
