What is a lambda expression, Computer Engineering

Assignment Help:

 A Lambda expression is not anything but an Anonymous Function, can have expressions and statements. Lambda expressions can be used mostly to make delegates or expression tree types. Lambda expression uses lambda operator => and read as 'goes to' operator.

 

Left side of this operator specifies the input parameters and haves the expression or statement block at the right side.

 

Example: myExp = myExp/10;

 

Now, let see how we can assign the above to a delegate and make an expression tree:

 

delegate int myDel(int intMyNum);

static void Main(string[] args)

{

//assign lambda expression to a delegate:

myDel myDelegate = myExp => myExp / 10;

int intRes = myDelegate(110);

Console.WriteLine("Output {0}", intRes);

Console.ReadLine();

 

//Create an expression tree type

//This needs System.Linq.Expressions

Expression myExpDel = myExp => myExp /10;

}

 

Note:

The => operator has the similar precedence as assignment (=) and is right-associative.

 

Lambdas are used in method-based LINQ queries as arguments to standard query operator methods such as Where.
