与Dapper一起使用SQL Server存储过程的错误日期

我正在使用存储过程和Dapper从表中检索数据。存储过程在SQL Server中执行时工作正常，并返回所需的信息。与Dapper一起使用SQL Server存储过程的错误日期

但是，当我使用Dapper运行存储过程并检索Date时，Date返回为01/01/0001。

这里是我的存储过程，而在SQL Server中完美的作品：

在SQL Server中的结果：

My Stored procedure Results in SQL Server

使用小巧精致得到的结果的方法：

public List<RankingsModel> GetRankingsByEventAndGender(string eventName, string gender) { 
    using (IDbConnection connection = new System.Data.SqlClient.SqlConnection(Helper.GetConString("GARanks"))) { 
     var output = connection.Query<RankingsModel>($"dbo.spRankings_GetByEventAndGender @Event, @Gender", new { Event=eventName, Gender=gender}).ToList(); 
     return output; 
    } 
}
