if (item.FileSystemObjectType == FileSystemObjectType.File)
{
Console.WriteLine("List item is a file.");
}
Console.ReadLine();
}
}
private static SecureString GetPassword()
{
ConsoleKeyInfo info;
//Get the user's password as a SecureString
SecureString securePassword = new SecureString();
do
{
info = Console.ReadKey(true);
if (info.Key != ConsoleKey.Enter)
{
securePassword.AppendChar(info.KeyChar);
}
}
while (info.Key != ConsoleKey.Enter);
return securePassword;
}
