c# - 如何在一个属性中存储多个值类型？

Question

我有一个正在创建的事件类，目前如下所示：

public class SharePointOnErrorEventsArgs : EventArgs
{
    public SharePointOnErrorEventsArgs(string message, bool showException, Exception exception)
    {
        Message = message;
        Exception = exception;
        ShowException = showException;
    }

    /// <summary>
    /// Property to allow the storage of a more verbose and explainable error message
    /// </summary>
    public string Message { get; private set; }

    /// <summary>
    /// Object to store full exception information within
    /// </summary>
    public Exception Exception { get; private set; }

    /// <summary>
    /// Boolean value allows for verbose messages to be sent up the stack without
    /// the need for displaying a full exception object, or stack trace.
    /// </summary>
    public bool ShowException { get; private set; }
}

现在，我不想发送trueor falseforshowException我想发送三个值之一Debug，Info或者Error- 我该如何处理这样的事情？我真的不想使用字符串，因为我想始终将其限制为这三个值之一，但我不确定在使用属性时如何处理这个问题。

您可以使用枚举：

public enum ShowExceptionLevel
{
    Debug,
    Info,
    Error
}

所以你的课程将是：

public class SharePointOnErrorEventsArgs : EventArgs
{

    public enum ShowExceptionLevel
    {
        Debug,
        Info,
        Error
     }

    public SharePointOnErrorEventsArgs(string message, ShowExceptionLevel showExceptionLevel, Exception exception)
    {
        Message = message;
        Exception = exception;
        ShowException = showException;
    }

    /// <summary>
    /// Property to allow the storage of a more verbose and explainable error message
    /// </summary>
    public string Message { get; private set; }

    /// <summary>
    /// Object to store full exception information within
    /// </summary>
    public Exception Exception { get; private set; }

    /// <summary>
    /// Boolean value allows for verbose messages to be sent up the stack without
    /// the need for displaying a full exception object, or stack trace.
    /// </summary>
    public ShowExceptionLevel ShowException { get; private set; }
}
