Its very easy to overload operators in C# 4.0.

You can add different overloading values such as +,-,* or /

But we will be focusing on "+" in this blog.

Lets say we create a class named Word:


public class Word
{

public string Text
{
get;
set;
}

public static string operator +(Word w1, Word w2)
{
return w1.Text + " " + w2.Text;
}

public static Word operator +(Word w, int j)
{

return new Word()
{
Text=w.Text + j.ToString()
};
}

public override string ToString()
{
return Text;
}


}
class Program
{
static void Main(string[] args)
{

Word word1 = new Word() { Text = "Hello" };
Word word2 = new Word() { Text = "World" };

Console.WriteLine(word1);
Console.WriteLine(word2);
Console.WriteLine(word1 + word2);
Console.WriteLine(word1 + 7);

Console.ReadLine();
}
}



As you can see its very easy to overload an operator.You can add these (+,-,*,/) values after operator keyword.

And im fully surprised how fast C# 4.0 compiler is! Its like as if im building an application in C++


Dont you think?
