What is C# Delegate?
C# Delegate refers to methods with a certain parameter list to define a method signature. You can use a delegate to associate it with any method and a compatible signature type. Users and developers can invoke the method using delegate instances.
You can process delegates to use smoothen methods as arguments or other methods. All event handlers are triggered using a custom method like a window control. The method used in the process may be the instance method or static method.
Using delegate c#, you can modify calls programmatically or even include a code into existing classes. The signature of a method usually never returns a value. However, in delegates, the signature always comes with a return value.
In the programming language you can compare a couple of objects in your app. And you can opt for a delegate method for its algorithm through a sort algorithm.
What Is the Process Of Assigning Delegates?
When you are working on c# delegate, you have to follow all its processes and methods carefully.
Step 1: Declaring a Delegate
This is the primary step. You can declare your delegate by using a keyword and signature.
Use the following syntax to declare your delegate:
Step 2: Setting up a Target Method
When your step-1 is cleared, you have to set your new target method. In computer programming parlance, it’s also called lambda expression. Just insert an object of the delegate using the appropriate keyword and a passing method with a signature that matches with the signature originally created in step-1.
Alternatively, you can create a target method without creating a delegate object.
Step 3: Invoke a Delegate (Optional)
It can be further modified or invoked using the () operator symbols.
Multicast Delegate: Everything That You Should Know
Many people ask what is delegate in c#? While we have explained all vital points to it in the above sections, now we’ll look into its vital topic: Multicast Delegate.
In simple terms, the multicast delegate is a process of delegating a task through multiple methods. You can use + or += operator to include a new function. Contrarily, if you use – and -=, the operator will remove that function.
Generic Delegate is another crucial C# Delegate Example, which you shouldn’t miss out. Under this process, you have to use a generic type of parameters or return type. While setting targets, the use of generic types must be specified or else your programming may go wrong.
C# Delegate is always a tricky and lengthy subject. It might be easy for a programmer to understand all the nuances of Delegates but for a non-tech savvy person, it’s not so simple.
However, we have a programming hack for you. If you want a shortcut to a ‘delegate process’, just use the Action and Function command to complete necessary operations.
Always remember that function will return a certain value after its processing—while action represents a complete act and won’t return any value.See less
