如何在C＃中使用Dapper將對象放入字典中？

Question

我有類似下面的詞典：

Dictionary<string,SP> dict; 

包含字符串和SP對象。

我想做到以下幾點

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)); 

上面的代碼無法正常工作。我如何用上面的信息創建一個SP對象。我有一個構造函數，它接受這三個參數。

Answer 1

1. 創建適當的模型

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

2. 地圖查詢到性能建模，選擇它以字典

   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);
