Outputting generic list to array

[Guest]

I need to output a Generic List to an array, but Ive been unable to.

The list looks like:
List<Employee> emp = new List<Employee>();

When I use ToArray() with it:
string[] empArray = emp.ToArray();
I get the error message:
Cannot implicitly convert type 'NgItIts.AD2Service.Ad2Employee[]' to
'string[]'
The online docs show a GetRange(), but Im unable to get to work.

The Employee class has useraccount, name, emailaddress, and organization
properties.

Any help is appreciated!

Try this code.

Employee[] empArray = emp.ToArray();

Since emp is a List<Employee>, emp.ToArray returns an array of
Employees, not strings.

If you want to convert it to an array of strings, you'll have to
convert each Employee to a string individually, e.g. with ToString().

I can certainly do that. But then what is the purpose of ToArray()?

converting from List<T> to T[].

Of course, you can do (not compile-tested):

yes, it's working! thanks

tested with:

string[] empArray = Array.ConvertAll<Employee, string>(emp.ToArray(), delegate(Employee from) { return from.ToString(); });
