As I said in the comments, you could embed it in a while
loop
bool continue = true;
while (continue)
{
Console.WriteLine("Enter Customer Details (s)");
Console.WriteLine("Enter usage data (u)");
Console.WriteLine("Display usage data (d)");
Console.WriteLine("Exit (e)");
string menu = Console.ReadLine();
switch (menu)
{
case "s":
//statement
break;
case "u":
//statement
break;
case "d":
//statement
break;
case "e":
default:
continue = false;
break;
}
}
solved Switch statements for a Menu (c#)
