Output:
Practical 8:
A program to use try and catch for exception handling –
Output:
Division by zero
y=1
Practical 9:
A program to demonstrate ilist interfaces -
using System;
using System.Collections.Generic;
class Program
{
static void Main()
{
int[] a = new int[3];
a[0] = 1;
a[1] = 2;
a[2] = 3;
Display(a);
List<int> list = new List<int>();
list.Add(5);
list.Add(7);
list.Add(9);
Display(list);
Console.ReadLine();
}
static void Display(IList<int> list)
{
Console.WriteLine("Count: {0}", list.Count);
foreach (int num in list)
{
Console.WriteLine(num);
}
}
}
Output:
Count: 3
123
Count: 3
579
Practical 10:
1. A program to demonstrate Dictionary interface –
using System;
using System.Collections.Generic;
class Demo {
// Main Method
static public void Main () {
// Creating a dictionary
// using Dictionary<TKey,TValue> class
Dictionary<int, string> My_dict1 =
new Dictionary<int, string>();
// Adding key/value pairs
// in the Dictionary
// Using Add() method
My_dict1.Add(1123, "Welcome");
My_dict1.Add(1124, "to");
My_dict1.Add(1125, "Demo");
Foreach (KeyValuePair<int, string> ele1 in My_dict1)
{
Console.WriteLine("{0} and {1}",
ele1.Key, ele1.Value);
}
Console.WriteLine();
// Creating another dictionary
// using Dictionary<TKey,TValue> class
// adding key/value pairs without
// using Add method
Dictionary<string, string> My_dict2 =
new Dictionary<string, string>(){
{"a.1", "Dog"},
{"a.2", "Cat"},
{"a.3", "Pig"} };
Foreach (KeyValuePair<string, string> ele2 in My_dict2)
{
Console.WriteLine("{0} and {1}", ele2.Key, ele2.Value);
}
}
}
Output:
1123 and Welcome
1124 and to
1125 and Demo
a.1 and Dog
a.2 and Cat
a.3 and Pig
2. A program to demonstrate iDictionary interface -
using System;
using System.Collections.Generic;
class Program
{
static void Main()
{
Dictionary<string, string> dict = new Dictionary<string, string>();
dict["Tom"] = "Bob";
WriteKeyA(dict);
SortedDictionary<string, string> sort = new SortedDictionary<string, string>();
sort["Tom"] = "Jerry";
WriteKeyA(sort);
Console.ReadLine();
}
static void WriteKeyA(IDictionary<string, string> i)
{
Console.WriteLine(i["Tom"]);
}
}
Output:
Bob
Jerry

PREFACE
This practical file has been prepared in partial
fulfilment of the requirement for the Subject: C#
of the programme B.C.A. (Sem. V) in the academic
year 2019-2020.
Completing the project helped me to deepen and widen
practical knowledge in C#.
All constructive criticism and feedback is cordially
invited.
CERTIFICATE
This is to certify that Anshuman Srivastava has made
this C# Practical file under the supervision and
guidance of my subject teacher “Mrs. Rashmi Kuksal”
for the Academic Session 2019-2020 for partial
fulfillment of Hemvati Nandan Bahuguna Garhwal
University.

ACKNOWLEDGEMENT
I would like to express my special thanks of gratitude to
my respected Principal and my subject teacher “Mrs.
Rashmi Kuksal” for their guidance and support in
completing the practical file.
Secondly, I would also like to thank my parents and
friends who helped me a lot in finalizing this project
within the limited time frame.
