Problem with Generic IList as return type.

[Nikhil Vaghela]

Hi,   Problem overview I am going to use iBatis.Net latest version which supports .NET 2.0.   I have a wrapper class as given in the old example NPetShop that is BaseSQLMapDao in my Persistance layer which is having methods like “ExecuteQueryForList” which actually calls sqlMapper’s QueryForList method of iBatisNet.DataMapper Now .NET 2.0 supports generic IList and iBatis also supports this feature.   Actual problem   I will be calling ExecuteQueryForList method from my BuisnessObject’s sqlMapDao say for example “EmployeeSqlMapDao.cs” or “DepartmentSqlMapDao.cs” in my persistence layer.   Now the problem is if I use genericsList my BaseSqlMapDao doest not know which type of IList it is returning !!!! e.g public IList GetEmployeeListForDepartment(string DepartmentID) { return ExecuteQueryForList("GetEmployeesForDepartment", DepartmentID);   //above given is a method of BaseSqlMapDao class }   this works fine but if I use generic IList like as follows   public IList<Employee> GetEmployeeListForDepartment(string DepartmentID) { return ExecuteQueryForList("GetEmployeesForDepartment", DepartmentID);   } Now what will i be having as return type in this case for ExecuteQueryForList as that method does not know which type of Objects are stored in the Ilist!!!! And if I make its return type IList<Object> i will have to cast it each and every item in IList<Object> to my custome object’s Ilist<MyCustomObject> which I don’t want as its not good method   So how can I solve the problem ???? I hope I could describe my question properly.   Any help will be greatly appreciated. Thanks. Nikhil.
