need help with c# conversion

[EmNewbie]

I'm new to c# and I need help converting this-any help would be greatly appreciated.-I was previously in a java class and now I'm in c# class with the same assignment.

public class Furniture
{
public static void main(String[] args)
{
int tree = 0;
Scanner scan = new Scanner(System.in);
System.out.println("Enter \n 1 for pine \n 2 for oak \n 3 for mahogany");
try
{
tree = scan.nextInt();
}
catch(Exception e)
{
System.out.println("Invalid input. Only numbers are accepted");
}
int cost = 0;
if(tree == 1)
cost = 100;
else if(tree == 2)
cost = 225;
else if(tree == 3)
cost = 310;
else
cost = 0;
String tab = "";
if(tree == 1)
tab = "Pine";
else if(tree == 2)
tab = "Oak";
else if(tree == 3)
tab = "Mahogany";
System.out.println("This " + tab + " table will cost you $" + cost);
}

Hi,

This isn't too hard...

    public class Furniture
    {
    public static void main(String[] args)

main is slightly difference in C#, but not greatly. As you're not bothering to pass anything in...

static void Main()

Quick changes here....

    Scanner scan = new Scanner(System.in);
    System.out.println("Enter \n 1 for pine \n 2 for oak \n 3 for mahogany");
    try
    {
    tree = scan.nextInt();

becomes

int tree = 0;
while (tree < 1 || tree > 3)
Console.Write("Enter \n 1 for pine \n 2 for oak \n 3 for mahogany");
string number = Console.Read();
tree = Convert.ToInt32(string);

I'd now change these to a switch....

    int cost = 0;
    if(tree == 1)
    cost = 100;
    else if(tree == 2)
    cost = 225;
    else if(tree == 3)
    cost = 310;

Now becomes

switch(tree)
{
   case 1 : cost = 100; tab = "Pine"; break;
   case 2 : cost = 225; tab = "Oak"; break;
   case 3 : cost = 310; tab = "Mahogany"; break;
}

And finally...

    System.out.println("This " + tab + " table will cost you $" + cost);

becomes

Console.WriteLine("This {0} table will cost you ${1}", tab, cost);

HTH

While I'm nowhere near an expert, I'm at a loss over what System.in is - it's certainly not listed on MSDN. Would it not be simpler to have

string foo = ""
int tree = 0;
foo=Console.ReadLine();
tree = Convert.ToInt32(foo);

With something around the Convert to check for the value?
