自定义特性的使用--扩展enum的使用

public class RemarkAttribute : Attribute
{
public RemarkAttribute(string remark)
{
_Remark = remark;
}

private string _Remark;

public string Remark

get
{

}
}

/// </summary>

/// <summary>
/// 冻结
/// </summary>
[Remark("Frozen")]
Frozen = 1,
/// <summary>
/// 删除
/// </summary>
[Remark("删除")]
Delete = 2
}
