C# Jagged Array Meaning:
It is basically an array. All its elements, likewise, are arrays which may be of variable dimensions, lengths, forms, and sizes. These are special array types in C#.
Arrays can be easily initialised upon declaration of specific nature or types. The elements of an array can be defined as reference types. Such arrays are initialized to null. Under it, it is permissible for a programmer to mix jagged and multidimensional arrays.
Under this programming system, the number of rows or lines may remain fixed at the declaration time, but the number of columns can vary or be made to vary. Arrays can be two dimensional: one dimensional and two dimensional.
Following are the main points of special array-types in C#:
- Mixing jagged and multidimensional arrays are possible
- It may store arrays instead of literal values, in some cases
- Arrays can be accessed upon using the specific index number
- Loops can be used or applied upon to iterate through each element of the jagged array
- Arrays can increase the ability of high-level languages in programming
- While working with complex algorithms in programmes, arrays can be useful.
- In memory management, arrays play a crucial role.
C# Arrays are capable of storing various values under the name of a single variable. It makes things easier where the need to store data in a multidimensional way using the same variable name arises. It acts as the most important component or aspect of the high-level programming language.See less

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
