Question

在我的应用程序的服务器端，我使用MS SQL Server 2014 Express。在客户端，我有C＃WPF应用程序，我在那里有以下枚举类型：

/// <summary>
/// User authorization level.
/// </summary>
public enum UserAuthorizationLevel
{
    /// <summary>
    /// Only visual inspection is allowed (the first lower level).
    /// </summary>
    Inspection,
    /// <summary>
    /// Some settings in apparatus are allowed (the second level).
    /// </summary>
    SettingDeviceParametersApplied,
    /// <summary>
    /// Some more setting in apparatus are allowed than in the second level (the third level).
    /// </summary>
    Maintenance,
    /// <summary>
    /// Apparatus manufacturer level - full access is allowed (the highest level).
    /// </summary>
    Manufacturer
}

我可以在服务器端（在MS SQL Server数据库中）创建此类型，并将此类型用作数据库表中字段的类型吗？

我建议你看一下：Best method to store Enum in Database

你拥有的是一个Enum，而不是一个类型。枚举转换为Int类型。所以你会有这样的事情：

/// <summary>
/// User authorization level.
/// </summary>
public enum UserAuthorizationLevel
{
    /// <summary>
    /// Only visual inspection is allowed (the first lower level).
    /// </summary>
    Inspection = 0,
    /// <summary>
    /// Some settings in apparatus are allowed (the second level).
    /// </summary>
    SettingDeviceParametersApplied = 1,
    /// <summary>
    /// Some more setting in apparatus are allowed than in the second level (the third level).
    /// </summary>
    Maintenance = 2,
    /// <summary>
    /// Apparatus manufacturer level - full access is allowed (the highest level).
    /// </summary>
    Manufacturer = 3
}

如何在MS SQL Server 2014中创建新的数据类型？
