1、將實體轉換為Hashtable，用於將實體引數處理為hashtable,方便sql引數傳遞

 1 　　　　　/// <summary>
 2         /// 將實體轉換為Hashtable
 3         /// </summary>
 4         /// <typeparam name="T">實體型別</typeparam>
 5         /// <param name="obj">實體例項</param>
 6         /// <returns>Hashtable</returns>
 

 7         public static Hashtable ConvertEntityToHashtable<T>(T obj)
 8         {
 9             Hashtable hst = new Hashtable();
10             try
11             {
12                 Type type = obj.GetType();
13                 foreach (PropertyInfo pi in type.GetProperties())
14                 {
 
15                     PropertyInfo property = type.GetProperty(pi.Name);
16                     hst.Add(pi.Name, property.GetValue(obj, null));
17                 }
18                 return hst;
19             }
20             catch (Exception ex)
21             {
22                 System.Console.Out.WriteLine(ex.Message);
 
23                 return null;
24             }
25         }
