Lambda Expressions in C#
Now we are going to learn about Lambda expressions in c#.
Introduction
A lambda expression make program easier, lambda expression is a anonymous function by creating delegates. we can pass local function by the value of the function calls.
Example
namespace ConsoleApplication2
{
delegate bool D();
delegate bool D2(int i);
class Test
{
D del;
D2 del2;
public void TestMethod(int input)
{
int j = 0;
del = () => { j = 10; return j > input; };
del2 = (x) => { return x == j; };
Console.WriteLine("j = {0}", j);
bool boolResult = del();
Console.WriteLine("j = {0}. b = {1}", j, boolResult);
}
static void Main()
{
Test test = new Test();
test.TestMethod(5);
bool result = test.del2(10);
Console.WriteLine(result);
Console.ReadKey();
}
}
}
Output
