使用对db的LINQ调用设置Model类

Question

我对MVC / LINQ很新，所以请耐心等待。我想检查TransmissionStatus var是否为false，如果是这样的linq到db来拉出相应的失败消息。

class AuditLogManagement
{
    public int ID { get; set; }
    public DateTime Date { get; set; }
    public string MsgType { get; set; } //possibly enum?
    public AuditLogEventDetails EventDetails { get; set; }
    public string MsgContents { get; set; }
    public bool TransmissionStatus { get; set; }
    public string FailedTransmissionMsg
    {
        get
        {
            if (!TransmissionStatus)
            {
                //linq to db to return failed xmission message
            }
        }
    }
}
