我有使用与一组 tsql 存储过程通信的 DAL (ADO.NET) 的 MVC 3 应用程序？我想在我当前的解决方案中添加一个新的 MVC 项目。我需要在 2 MVC 项目（“监视器”和“审计”）可以共享的单独项目中拥有 DAL。
下面是当前的 DAL（位于“Monitor”MVC 项目的文件夹中）代码。我的问题是我的签名像 IEnumerable 位于 Monitor.Models 和 IEnumerable 位于 Audit.Models 中。我是否需要将 DAL 设为通用以避免需要引用 DAL 中的模型？
Ex:
**//Is this bad practice?**
using Monitor.Models;
using Adit.Models;
namespace Monitor.DAL
{
public class QuestionDAL
{
static ILog log = log4net.LogManager.GetLogger(typeof(QuestionDAL));
private string _connectionString = WebConfigurationManager.ConnectionStrings["NexGenContext"].ToString();
public IEnumerable<AgencyTerm> SearchAgencies(string ori, string name)
{
log.Debug("Executing: SearchAgencies(string ori, string name)");
List<AgencyTerm> agencies = new List<AgencyTerm>();
using (var conn = new SqlConnection(_connectionString))
{
var com = new SqlCommand();
com.Connection = conn;
com.CommandType = CommandType.StoredProcedure;
string term = "Ori";
if (!String.IsNullOrEmpty(ori))
{
term = "Ori";
com.Parameters.Add(new SqlParameter
{
ParameterName = "@ORI",
Value = ori
});
}
if (!String.IsNullOrEmpty(name))
{
term = "legal_name";
com.Parameters.Add(new SqlParameter
{
ParameterName = "@Name",
Value = name
});
}
com.CommandText = "Review_Get_Agency_List";
var adapt = new SqlDataAdapter();
adapt.SelectCommand = com;
var dataset = new DataSet();
adapt.Fill(dataset);
agencies = (from c in dataset.Tables[0].AsEnumerable()
select new AgencyTerm()
{
label = c[term].ToString(),
id = c["Agency_Id"].ToString()
}).ToList<AgencyTerm>();
return agencies;
}
}
public IEnumerable<User> GetUsers()
{
log.Debug("Executing: GetUsers()");
List<User> users = new List<User>();
using (var conn = new SqlConnection(_connectionString))
{
var com = new SqlCommand();
com.Connection = conn;
com.CommandType = CommandType.StoredProcedure;
com.CommandText = "Review_Get_Users";
var adapt = new SqlDataAdapter();
adapt.SelectCommand = com;
var dataset = new DataSet();
adapt.Fill(dataset);
users = (from c in dataset.Tables[0].AsEnumerable()
select new User()
{
User_ID = Convert.ToInt32(c["User_ID"]),
Department = c["Department"].ToString(),
Enabled = Convert.ToBoolean(c["Enabled"]),
Email = c["Email"].ToString(),
User_First_Name = c["User_First_Name"].ToString(),
User_Last_Name = c["User_Last_Name"].ToString(),
Location = c["Location"].ToString(),
User_Name = c["User_Name"].ToString()
}).ToList<User>();
return users;
}
}
