Hi Dipa Mehta, You can store different data types in an array using two methods. Method 1: Object array, because of all the type in .net is inherit from object type, object[] array= new object[2]; array[0]=1; array[1]= "Ravishankar" ; Method 2: We can use ArrayList class like below ArrayList arrlist= new ArrayList(); arrlist.Add(1); arrlist.Add( "Ravishankar" );

Hi Dipa check this namespace StoreMixedDatatypes { class Program { static void Main( string [] args) { object [] MyArray = new object [3]; MyArray[0] = "Rajanikant" ; MyArray[1] = 100; Person exp = new Person(); exp.Name = "Rajanikant Hawaldar" ; exp.Age = 33; MyArray[2] = exp; } } class Person { public string Name { get ; set ; } public int Age { get ; set ; } } }

Hi Dipa: Please try below code, it is given detailed solution of your problem 1.Make the array elements: struct { enum { is_int, is_float, is_char } type; union { int ival; float fval; char cval; } val; } my_array[10]; 2. So if you want to store an int in the first element: my_array[0].type = is_int; my_array[0].val.ival = 3; 3.Switch Statement: switch (my_array[n].type) { case is_int: // Do stuff for integer, using my_array[n].ival break ; case is_float: // Do stuff for float, using my_array[n].fval break ; case is_char: // Do stuff for char, using my_array[n].cvar break ; default : // Report an error, this shouldn't happen }
