Multiple Catch in C#

Hi Vineet,

Yes. Multiple catch blocks may be put in a single try block.

Example:-

using System; 
 
public class ExcDemo4 { 
 public static void Main() { 
 // Here, numer is longer than denom. 
 int[] numer = { 4, 8, 16, 32, 64, 128, 256, 512 }; 
 int[] denom = { 2, 0, 4, 4, 0, 8 }; 
 
 for(int i=0; i < numer.Length; i++) { 
 try { 
 Console.WriteLine(numer[i] + " / " + 
 denom[i] + " is " + 
 numer[i]/denom[i]); 
 } 
 catch (DivideByZeroException) { 
 // catch the exception 
 Console.WriteLine("Can't divide by Zero!"); 
 } 
 catch (IndexOutOfRangeException) { 
 // catch the exception 
 Console.WriteLine("No matching element found."); 
 } 
 } 
 } 
}


But for every try block there must be a corresponding catch block.

Example:-

using System;
 
public class NestTrys {
  public static void Main() {
    // Here, numer is longer than denom.
    int[] numer = { 4, 8, 16, 32, 64, 128, 256, 512 };
    int[] denom = { 2, 0, 4, 4, 0, 8 };
 
    try { // outer try
      for(int i=0; i < numer.Length; i++) {
        try { // nested try
          Console.WriteLine(numer[i] + " / " +
                             denom[i] + " is " +
                             numer[i]/denom[i]);
        }
        catch (DivideByZeroException) {
          // catch the exception
          Console.WriteLine("Can't divide by Zero!");
        }
      }
    } 
    catch (IndexOutOfRangeException) {
      // catch the exception
      Console.WriteLine("No matching element found.");
      Console.WriteLine("Fatal error -- program terminated.");
    }
  }
}


Thanks
