我必须比较来自UI和来自SQL Server 2008的IEnumerable数据的IEnumerable数据，并且必须从UI插入/更新新元素到数据库并从元素中删除元素基于UI数据的数据库。比较两个IEnumerable并根据比较结果删除/插入
我有在DB Distribution_X_ListType表：
DistributionID ListTypeID EmployeeNumber DepartmentID LocationID
1 2 84528 NULL NULL
1 3 NULL 8051 NULL
1 5 NULL NULL 319
我有一个项目的界面如下：
public interface IDistributionList : IEntity
{
string Name { get; set; }
bool ActiveFlag { get; set; }
...........................
...........................
IEnumerable<IDistributionListType> ListTypes { get; set; }
}
的另一个接口是：
public interface IDistributionListType
{
int? DistributionID { get; set; }
int ListTypeID { get; set; }
int EmployeeNumber { get; set; }
int DepartmentID { get; set; }
int LocationID { get; set; }
}
在另一个项目中，我具有Save功能，如下所示：
public int Save(IDistributionList distributionList)
{
SqlDataReader reader = null;
int rowsaffected = 0;
try
{
sqlcommand = new SqlCommand("spGetDistributionListTypeByID", con); //spGetDistributionListTypeByID - This SP returns all the members from Distribution_X_ListType table for the given distribution ID
sqlcommand.CommandType = CommandType.StoredProcedure;
sqlcommand.Parameters.AddWithValue("@Distribution_ID", distributionList.ID);
reader = sqlcommand.ExecuteReader();
while (reader.Read())
{
????Value Should be stored in an IDistributionListType variable,say IDistributionListTypeFromDB
}
????IDistributionListType from function parameter(Lets say from UI) should be compared with the above IDistributionListTypeFromDB data.
????Insert/Delete should be done in DB by comparing the data.
}
}
从UI让IDistributionListType的价值：
DistributionID ListTypeID EmployeeNumber DepartmentID LocationID
1 2 84528 NULL NULL
1 5 NULL NULL 64
从DB让IDistributionListType的价值：
DistributionID ListTypeID EmployeeNumber DepartmentID LocationID
1 2 84528 NULL NULL
1 3 NULL 8051 NULL
1 5 NULL NULL 319
我需要从UI的数据来更新数据库。我有两个的SP为：
spInsertUpdateDistributionListType - Insert/Update Distribution_X_ListType table based on DistributionID and listtypeID
spDeleteDistributionListType - Delete Distribution_X_ListType table based on DistributionID and listtypeID
我不知道如何在代码????区域（在.net代码中提到）。有人请帮忙。提前致谢。
