Anonymous Methods in C#
Pass a code block as a delegate parameter in C#, using the Anonymous methods in C#. Anonymous methods are the methods without a name, just the body.
This is how you can declare Anonymous methods −
delegate void DemoMethod(int n);
...
DemoMethod dm = delegate(int a) {
Console.WriteLine("Our Anonymous Method: {0}", a);
};As shown above, the following is the body of the anonymous method −
Console.WriteLine("Our Anonymous Method: {0}", a);Example
You can try to run the following code to implement Anonymous methods in C# −
using System;
delegate void Demo(int n);
namespace MyDelegate {
class TestDelegate {
static int num = 10;
public static void DisplayAdd(int p) {
num += p;
Console.WriteLine("Named Method: {0}", num);
}
public static void DisplayMult(int q) {
num *= q;
Console.WriteLine("Named Method: {0}", num);
}
public static int getNum() {
return num;
}
static void Main(string[] args) {
Demo dm = delegate(int x) {
Console.WriteLine("Anonymous Method: {0}", x);
};
//calling the delegate using the anonymous method
dm(15);
//instantiating the delegate using the named methods
dm = new Demo(DisplayAdd);
//calling the delegate using the named methods
dm(10);
//instantiating the delegate using another named methods
dm = new Demo(DisplayMult);
//calling the delegate using the named methods
dm(4);
Console.ReadKey();
}
}
}Output
Anonymous Method: 15 Named Method: 20 Named Method: 80
