Accepted answer
Try this:

using System;

delegate int MyDelegate(int x, int y);

class Program
{
static void Main()
{
Console.WriteLine("Enter two integers\n");
Console.Write(" First integer : ");
int i1 = int.Parse(Console.ReadLine());
Console.Write(" Second integer : ");
int i2 = int.Parse(Console.ReadLine());
MyDelegate del = new MyDelegate(Minimum);
Console.WriteLine("\nThe smaller of {0} and {1} is : {2}", i1, i2, del(i1, i2));
del -= Minimum; // remove Mimimum from invocation list
del += Maximum; // add Maximum to invocation list
Console.WriteLine("The larger of {0} and {1} is : {2}", i1, i2, del(i1, i2));
Console.ReadKey();
}

static int Minimum(int x, int y)
{
if (x < y) return x;
return y;
}

static int Maximum(int x, int y)
{
if (x > y) return x;
return y;
}
}

Great, thank you !!
Now i found another task

To create delegate who will call two classes Maximum(int x, int y) and Minimum (int x, int y) with method that prints the value. To write code that will use delegate and first will get method Minimum and later Maximum.

add System.Linq in directives

or
Use below code if you are using the framework which doesn't support the LINQ.

static void Main(string[] args)
{
string word =System.Console.ReadLine();

if (word == null)
return;

var arrWord = word.Split(' ');
foreach (var wrd in arrWord)
{
int count = 0;
for (int i = 0; i < wrd.Length; i++)
{
if (wrd.Substring(i, 1).ToLower() == "e")
count++;
}

if(count>=3)
Console.WriteLine(wrd + " "+count.ToString());
}
Console.ReadKey();
}

Try this:

using System;
using System.Collections.Generic;
using System.Text.RegularExpressions;

class Program
{
static void Main()
{
List results = new List();

while(true)
{
Console.Write("\nEnter a string or q to quit : ");
string text = Console.ReadLine();
if (text == "q" || text == "Q") return;
results.Clear();
MatchCollection mc = Regex.Matches(text, @"\b\w+\b");

foreach(Match m in mc)
{
int eCount = 0;
foreach(char c in m.Value)
{
if (c == 'e' || c == 'E') eCount++;
}

if (eCount > 3) results.Add(m.Value);
}


Console.WriteLine("\nNumber of words which contain more than 3 'e's is {0}\n", results.Count);

if (results.Count > 0)
{
foreach(string w in results) Console.WriteLine(" {0}", w);
}
}
}
}

it has an error: Error 1 'string' does not contain a definition for 'Where' and no extension method 'Where' accepting a first argument of type 'string' could be found (are you missing a using directive or an assembly reference?) It has to enter sentence, with 5-6 words and print number of words that contain "e" more than 3 times. if the sentence has 2 words like that it will print > 2 Thanks for your fast reply

Are you looking for something like below code?

static void Main(string[] args)
{
string word =System.Console.ReadLine();

if (word == null)
return;

var arrWord = word.Split(' ');
foreach (var wrd in arrWord)
{
int count = wrd.Where((t, i) => wrd.Substring(i, 1).ToLower() == "e").Count();

if(count>=3)
Console.WriteLine(wrd + " "+count.ToString());

}
Console.ReadKey();
}
