在C＃中的日期時間SQLite bigint

我在我的UWP項目中使用SQLite。我的模型類有日期時間字段：在C＃中的日期時間SQLite bigint

public class EducationInfo 
{ 
    [SQLite.Net.Attributes.PrimaryKey, SQLite.Net.Attributes.AutoIncrement] 
    public int educationInfoId { get; set; } 
    public String Education { get; set; } 
    public bool Enabled { get; set; } 
    public DateTime StartDate { get; set; } 
    public DateTime EndDate { get; set; } 
    public int UserId { get; set; } 

    // Not in the DB 
    [Ignore] 
    public string FormattedStartDate { get; set; } 
    [Ignore] 
    public string FormattedEndDate { get; set; } 

    public EducationInfo() 
    {} 

    public EducationInfo(String edu, bool enabled, DateTime st, DateTime ed, int userId) 
    { 
     this.Education = edu; 
     this.Enabled = enabled; 
     this.StartDate = st; 
     this.EndDate = ed; 
     this.UserId = userId; 
    } 

}

的問題是，SQLite的創建日期時間字段爲BIGINT。我如何閱讀這個bigint並設置爲DateTime？

var education = connection.Table<EducationInfo>().Where(e => e.UserId == user.userID); 
         foreach(var edu in education) 
         { 
          EducationInfo educationInfo = new EducationInfo(); 
          educationInfo.StartDate = edu.StartDate; 
         }

上面的代碼不會返回錯誤，但日期值是錯誤的。 '
