您要求两次用户输入.第一个Console.ReadLine();是您输入"是"或"否"的内容,但是您的if/ else if声明再次要求输入.

Console.WriteLine("Are You Sure Your User: " + user + " And Pass: " + Pass + " is correct?  Yes/No");
var input = Console.ReadLine();
if (input == "Yes" || input == "yes")
{
   Console.WriteLine("You May now close this");
}
else if(input == "No" || input == "no")
{
   Console.WriteLine("Pleas Press enter");
   System.Diagnostics.Process.Start(Environment.GetCommandLineArgs()[0], Environment.GetCommandLineArgs().Length > 1 ? string.Join(" ", Environment.GetCommandLineArgs().Skip(1)) : null);
}
