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 ) { 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 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

Hi Vineet Multiple try block for single Catch block is not possible in C Sharp. But You can define multiple catch block for single Try block. Example: // Ordering catch clauses using System; class MyClass { public static void Main() { MyClass x = new MyClass(); try { string s = null; x.MyFn(s); } // Most specific: catch (ArgumentNullException e) { Console.WriteLine({0} First exception caught. e); } // Least specific: catch (Exception e) { Console.WriteLine({0} Second exception caught. e); } } public void MyFn(string s) { if (s == null) throw new ArgumentNullException(); } }

Hi There is multiple catch block for single try block. try { .... } catch (SqlException es) { // catch only SQL Exception } catch (OutOfMemoryException eo) { // catch only Out Of Memory Exception } hope this help.
