Lamda Expression

Lambda expression is an anonymous function that you can use to create delegates or expression tree types

Func<double, double> cpointer = x => x * 3.123; //Input and Output

Action<string> action = y => Console.WriteLine(y); //Void

Predicate<int> GreaterThanFive = z => z > 5; //Input and Always return Bool

double area = cpointer(2);

action("action display");

bool isGreater = GreaterThanFive(4);

BinaryExpression b1 = Expression.MakeBinary(ExpressionType.Add, Expression.Constant(10), Expression.Constant(20));

BinaryExpression b2 = Expression.MakeBinary(ExpressionType.Add, Expression.Constant(5), Expression.Constant(3));

BinaryExpression b3 = Expression.MakeBinary(ExpressionType.Subtract, b1, b2);

int result = Expression.Lambda<Func<int>>(b3).Compile()();
