Azure 存储中的默认值

Question

我正在我的 Azure 模型中定义一个属性，我想要它的默认值。我正在做的是这个

[DefaultValue(true)]
public Boolean SmsNotification { get; set; }

默认值仍然是 False。谁能告诉我如何解决这个问题？

Answer 1

您可以创建一个属性并将包装字段设置为 true:

public bool mSmsNotification = true;
public bool SmsNotification
{
    get { return mSmsNotification; }
    set { mSmsNotification = value; }
}

Answer 2

DefaultValueAttribute 就是：一个属性。文档很清楚：

A visual designer can use the default value to reset the member's value. Code generators can use the default values also to determine whether code should be generated for the member.

A DefaultValueAttribute will not cause a member to be automatically initialized with the attribute's value. You must set the initial value in your code.

不知道能不能说的更清楚一点

Answer 3

DefaultValue attribute does not cause the initial value to be initialized with 属性的 value.It 并没有在代码中设置属性的实际默认值，它只是为了设计.

所以 :

[DefaultValue(true)]
public bool SmsNotification
{
     get { return _smsNotification; }
     set { _smsNotification = value; }
}
