如何在C＃中使用Dapper將對象放入字典中？

Question

我有一本類似以下的字典：

Dictionary<string,SP> dict;

包含一個字符串和一個SP對象。

我想做以下

dict = conn.Query("SELECT routine_name,created,modified FROM PROCEDURES").toDictionary (
                        row => (string)row.Routine_Name,
                        row => new SP (Name=row.Routine_Name,Created=row.created,Modified=row.modified));

上面的代碼不起作用。 如何使用上述信息創建SP對象。 我有一個采用這三個參數的構造函數。

Answer 1

1. 創建合適的模型

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

2. 將查詢映射到模型屬性，將其選擇為字典

    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);
