Code:

using System;
namespace Wrox.JackFeng{
	class Order{
		public Order(){}
		
		public void OrderNumber(int[] iArray){
			foreach(int val in iArray){
				Console.Write(val+'\t');
			}
		}
	}
}

using Wrox.JackFeng
namespace Wrox.CadeFeng
{
	class Program{
		static void Main(){
			const string sSuggestion="Please input some Number form(0-100)!";
			const int zero=0;
			string sNum = string.Empty;
			int[] iArray ;
			int i=zero;
			bool condition = false;
			
			Console.WriteLine(sSuggestion);
			while(!condition){
				sNum = Console.ReadLine();
				iArray[i] = Convert.ToInt32(sNum);
					i++;
				if(Convert.ToInt32(sNum)==0)
					break;
			}	
			
			Order Order_ = new Order();
			Order_.OrderNumber(iArray);
		}
	}
}

Hello dear,

In C# when you declare an array, you should specify items count. for example:

Code:

int[] iArray = new int[20];

because you dont have specified length of array, you get error.
when you dont know length of array, you can resize the array.
or you can use generic lists:

Code:

using System;
namespace Wrox.JackFeng{
	class Order{
		public Order(){}
		
		public void OrderNumber(List<int> iArray){
			foreach(int val in iArray){
				Console.Write(val+'\t');
			}
		}
	}
}

using Wrox.JackFeng
namespace Wrox.CadeFeng
{
	class Program{
		static void Main(){
			const string sSuggestion="Please input some Number form(0-100)!";

			string sNum = string.Empty;

			List<int> iArray = new List<int>;
			
			Console.WriteLine(sSuggestion);
			while(1){
				sNum = Console.ReadLine();

				iArray.Add(Convert.ToInt32(sNum));


				if(Convert.ToInt32(sNum)==0)
					break;
			}	
			
			Order Order_ = new Order();
			Order_.OrderNumber(iArray);
		}
	}
}

click Thanks if it helps
