How can i give an error depending on the array input?

[lociteck]

Hello,
How can i give an error depending on the array input? This is my code

using System;
class MainClass
	
{
		public static void Main (string[] args)
		{
		int[] randomSizedArray;
		string sizeOfArray;
		int convertedSizeArray = -1;
		Console.WriteLine ("Please Enter the Size of the Array Between 1-99");
		sizeOfArray = Console.ReadLine();
		convertedSizeArray = Int32.Parse(sizeOfArray);	
		randomSizedArray= new int[convertedSizeArray];
		Random rnd = new Random();
		for (int i=0; i < convertedSizeArray; i++) {
			
    	randomSizedArray[i] = rnd.Next(1,99);
		
			
		}
			for (int i=0; i < convertedSizeArray; i++) 
{
    Console.WriteLine(randomSizedArray[i] + "");
			
}
		string swapindex1;
		string swapindex2;
		int index1;
		int index2;
		Console.WriteLine("Please Enter Index to swap");
		swapindex1 = Console.ReadLine();
     	index1 =  Int32.Parse(swapindex1);
		int temp = randomSizedArray[index1];
		Console.WriteLine ("Please Enter a Second Value to swap");	
		swapindex2 = Console.ReadLine();
     	index2 =  Int32.Parse(swapindex2);	
		randomSizedArray[index1] = randomSizedArray[index2];
		randomSizedArray[index2] = temp;
		 for (int j=0; j < convertedSizeArray; j++){
			Console.WriteLine(randomSizedArray[j]);
	}
		
	}	
		
 
}

So im going to give an error if the user inputs different number besides 1-99, please help you guys, i've never done any error coding.

Use an if to check whether or not the inputted value is within your range. Throw an error if it is outside the range.

Rabbit is right, keep a if check before forloop on sizeOfArray variable. If it falls outside the allowed range then throw error message to the user.
