Dictionary Value to object class!

Hi guys,

I have a class employees.

I have one generic class <tkey,tdata>

I have one dictionary <tkey,tdata>

I want to store the Employee info to a file.

After saving the object of Employees to Tdata (value) of dictionary, I cannot get the info of employee (firstname, lastname...) from dictionary in order to create a xml file.

Any idea to cast the value of dictionary to Employee to get the properties of employee class?

I can get the object of Employee by a foreach(var item in dictionary) => item.Value
but I cannot cast to get the properties of the employee class!

Thank you!

======code

Main Class:

EmployeeMNG<string,employees> empMNG= new EmployeeMNG<string,employees>();
 

Employees s= new Employees();
s.empNo = 11;
s.firstName = "khoaxml";
s.lastName = "nguyen";
s.address = "47 nguyen hong";
s.country = "VN";
 
empMNG.add("stu", s); ///add to dictionary
empMNG.save("file.xml");
 
Generic Class:
 
public class EmpMNG<tkey,tdata> : IEmpMNG<<tkey,tdata>
{
private Dictionary<tkey,tdata> cache;
 
//Constructor
public EmpMNG()
{
cache = new Dictionary<tkey,tdata>();
}
 
//add to dictionary
public TData add(TKey key, TData data)
{
if (!cache.ContainsKey(key))
{
cache[key] = data;
}
return cache[key];
}
public void Save(string xmlPath)
{
foreach (var item in cache)//cache is dictionary
{
Console.WriteLine(item.Value);//here I get object of Employee class, which is passed from the main class
//is there any way to get the properties of Employee from here? I dont know how to cast with the Dictionary, thank you!!
 
}
