Csharp Problems

It is best to use if-else. Change it by yourself.
You can check the information on your own.

Namespace _ 1a
{
Class Program
{
Static void Main (string [] args)
{
Console. WriteLine ("enter" 1 ", Press enter to input data \ r \ n enter" 2 ", Press enter to display data ");
Console. WriteLine ("enter" 3 ", Press enter to sort data \ r \ n enter" 4 ", Press enter to exit the system ");

Int max = 6; // The maximum number of arrays that can be stored
Int real = 0; // The number of actually stored instances.
Int [] nums = new int [max];

While (true)
{
String choiceInt = Console. ReadLine ();
Switch (choiceInt)
{
Case "1 ":
Nums = new int [max]; // when you press 1 again, save the new data.
Console. WriteLine ("enter a series of numbers :");
While (true)
{
String num = Console. ReadLine ();
Int temp = 0;
If (int. TryParse (num, out temp ))
{
// If the input is 2, sort the entered numbers.
If (temp = 2)
{
Goto case "2"; // goto is not safe and is not recommended
}
Else if (temp = 3)
{
Goto case "3"; // goto is not safe and is not recommended
}
