Question

DAL层中出现找不到可接受的类型

--------------------------------DAL层－－－－－－－－－－－－－－－
public static partial class EntPopedomService
{
public static EntPopedom AddEntPopedom(EntPopedom entPopedom)
{
string sql =
"INSERT entPopedom (popName)" +
"VALUES (@popName)";

sql += " ; SELECT @@IDENTITY";

try
{
SqlParameter[] para = new SqlParameter[]
{
new SqlParameter("@popName", entPopedom.popName)
};

int newId = DBHelper.GetScalar(sql, para);
return GetEntPopedomByID(newId);
}
catch (Exception e)
{
Console.WriteLine(e.Message);
throw e;
}
}
－－－－－－－－－－－－－－－－－－Model层－－－－－－－－－－－－

namespace Car.Models
{
public class EntPopedom
{

private int iD;
private string popName = String.Empty;

public EntPopedom() { }

public int ID
{
get { return this.iD; }
set { this.iD = value; }
}

public string PopName
{
get { return this.popName; }
set { this.popName = value; }
}

}
}
已经引用了Model层的命名空间了，我把
SqlParameter[] para = new SqlParameter[]
{
new SqlParameter("@popName", entPopedom.popName)
};

这段代码注释了，就不报错了，我现在不知道为什么会这样，
我用的是Vs2008 + SQL server2005

是不是没有引入其他层命名空间,请楼主再将问题描述得更清楚些!
