How to remove tab page dynamically?

Hi,

 

 I need to remove tabpage dynamically based on a result from database.DB result having tabpage names.

 

 SqlDataReader reader = command.ExecuteReader();
while (reader.Read())
{
string langname = reader.GetString(0);
TabControl.TabPages.Remove(langname);
}

 

Error showing in highlighted section saying it has some invalid arguments.

When I put a tabpage name manually instead of langname it is working.

How can I achieve this?

Thanks
