EFCore 中执行存储过程返回DataSet DataTable

在项目中由于需求，需要返回复杂的数据，需要执行存储过程，但是在DONETCORE2.0中，看官网文档执行的sql的有点操蛋，满足不了需求，就想到了ADO.NET

于是找资料，也没有合适的，就动手自己封装了一个。代码如下；

 public static class ExtendDbRepository
     {
         public static DataSet SqlQuery(this Db db, string spName, params SqlParameter[] paramsters)
         {
             SqlConnection connection = db.Database.GetDbConnection() as SqlConnection;
             SqlDataAdapter adapter = null;
             DataSet set = null;
             using (SqlCommand command = new SqlCommand(spName, connection))
             {
                 command.CommandType = CommandType.StoredProcedure;
                 command.CommandText = spName;
                 command.Parameters.AddRange(paramsters);
                 adapter = new SqlDataAdapter(command);

                 set = new DataSet();
                 adapter.Fill(set);
                 adapter.SelectCommand.Parameters.Clear();
                 adapter.Dispose();
                 command.Parameters.Clear();
                 command.Dispose();
                 connection.Close();
                 connection.Dispose();
                 return set;
             }
         }

         public static IEnumerable<TElement> SqlQuery<TElement>(this Db db, string sql, params object[] parameters) where TElement : new()
         {
             var connection = db.Database.GetDbConnection();
             using (var cmd = connection.CreateCommand())
             {
                 db.Database.OpenConnection();
                 cmd.CommandText = sql;
                 cmd.CommandType = System.Data.CommandType.StoredProcedure;
                 cmd.Parameters.AddRange(parameters);
                 var dr = cmd.ExecuteReader();
                 var columnSchema = dr.GetColumnSchema();
                 var data = new List<TElement>();
                 while (dr.Read())
                 {
                     TElement item = new TElement();
                     Type type = item.GetType();
                     foreach (var kv in columnSchema)
                     {
                         var propertyInfo = type.GetProperty(kv.ColumnName);
                         if (kv.ColumnOrdinal.HasValue && propertyInfo != null)
                         {
                             //注意需要转换数据库中的DBNull类型
                             var value = dr.IsDBNull(kv.ColumnOrdinal.Value) ? null : dr.GetValue(kv.ColumnOrdinal.Value);
                             propertyInfo.SetValue(item, value);
                         }
                     }
                     data.Add(item);
                 }
                 dr.Dispose();
                 return data;
             }
         }
     }
