Box.com API Usage - Get Folder Count as a service app - box

Question

We are creating an app that is meant to be used with a Service Account in your system; another user (user-2) has authorized this app by adding our app key to their Custom Application list. How do I get this User-2's UserID, so we can impersonate him and access his files list and files, etc. We need their UserID, so we can pass the "AS-User: " Header. And can this header be set using some property from within the .NET SDK - a sample code will be appreciated.

This does it for all enterprise users but you can easily put an if statement to get the user you're looking for.
static async Task MainAsync()
{
// rename the private_key.pem.example to private_key.pem and put your JWT private key in the file
var privateKey = File.ReadAllText(PRIVATE_KEY_FILE);
var boxConfig = new BoxConfig(CLIENT_ID, CLIENT_SECRET, ENTERPRISE_ID, privateKey, JWT_PRIVATE_KEY_PASSWORD, JWT_PUBLIC_KEY_ID);
var boxJWT = new BoxJWTAuth(boxConfig);
var adminToken = boxJWT.AdminToken();
Console.WriteLine("Admin Token: " + adminToken);
Console.WriteLine();
var adminClient = boxJWT.AdminClient(adminToken); // adminClient == serviceAccount
var userDetails = await adminClient.UsersManager.GetCurrentUserInformationAsync();
Console.WriteLine("\tAdmin User Details:");
Console.WriteLine("\tId: {0}", userDetails.Id);
Console.WriteLine("\tName: {0}", userDetails.Name);
Console.WriteLine("\tStatus: {0}", userDetails.Status);
Console.WriteLine();
var users = await adminClient.UsersManager.GetEnterpriseUsersAsync();
users.Entries.ForEach(i =>
{
Console.WriteLine("\t{0}", i.Name);
Console.WriteLine("\t{0}", i.Status);
if (i.Status == "active")
{
var userToken = boxJWT.UserToken(i.Id);
var userClient = boxJWT.UserClient(userToken, i.Id);
Task u = getUserItems(userClient, i.Id);
u.Wait();
}
});
}
static async Task getUserItems(BoxClient userClient, string id)
{
var userDetails = await userClient.UsersManager.GetCurrentUserInformationAsync();
Console.WriteLine("\nManaged User Details:");
Console.WriteLine("\tId: {0}", userDetails.Id);
Console.WriteLine("\tName: {0}", userDetails.Name);
Console.WriteLine("\tStatus: {0}", userDetails.Status);
Console.WriteLine();
Console.WriteLine("managed users older items");
var items = await userClient.FoldersManager.GetFolderItemsAsync("0", 500);
items.Entries.ForEach(i =>
{
Console.WriteLine("\t{0}", i.Name);
});
Console.WriteLine();
}
