C# 如何在C中使用Dapper将对象放入字典？

我有一本字典如下：

Dictionary<string,SP> dict;

上述代码不起作用。如何使用上述信息创建SP对象。我有一个构造函数，它接受这三个参数

创建合适的模型

public class SP {
    public string RoutineName { get; set; }
    public DateTime Created { get; set; }
    public DateTime Modified { get; set; }
}

将查询映射到模型属性，然后将其选择到字典

Dictionary<string, SP> dictionary = connection.Query<SP>(@"
    SELECT 
         routine_name AS RoutineName,
         created AS Created,
         modified AS Modified
    FROM PROCEDURES
").ToDictionary(m => m.RoutineName, m => m);

public class SP {
    public string RoutineName { get; set; }
    public DateTime Created { get; set; }
    public DateTime Modified { get; set; }
}

         modified AS Modified
    FROM PROCEDURES
").ToDictionary(m => m.RoutineName, m => m);
