BlockingCollection in C# - Introduction and Examples

BlockingCollection is a collection class which ensures thread-safety. Multiple threads can add and remove objects in BlockingCollection concurrently. It implements the producer-consumer pattern. In this pattern, there are two threads one is called producer and other is called consumer. Both threads share a common collection class to exchange data between them. BlockingC...

C# Action

A delegate in C# represents a reference type that encapsulates a method. When we declare a delegate type we specify some parameters and a return type. We can only store those methods in delegates which has same parameters and same return type. Microsoft introduced some pre-built delegates so that we don't have to declare delegates every time. Action is one of the pre-b...

C# Predicate

Predicate is a pre-built delegate in the .NET framework class library. Delegates are used to store method which has same parameters and return types as specify in the delegate type. Predicate is a generic delegate. It takes one parameter and returns a boolean value. Predicate delegate is used for check whether a parameter meets specify condition or not. ...

C# Hashtable

C# Hashtable class is a collection class where we can store data in the key/value pair. Hashtable is not type-safe. Hashtable is not generic and both key and value are based on object type. Hashtable is used to store unique keys data. If we try to assign value to already used key, it just overrides the previous stored data. It is based on the Hashing algorithm&n...

ArrayList are dynamic means we can add any number of items without specifying the size of it. ArrayList vs Array ArrayList and Array looks same. But there are some major differences between them. Differences are: Array is fixed in size. We specify the...

C# Generics

Generics are introduced in C# 2.0. It is the most powerful features of C#. In C# 1.0, when we design a class that use other types that is not known at defining the structure of the class, then type should be an object type. In the class, we have to typecast the type using boxing and unboxing and then we can use the type. Generics introduced the concept of type parameters. Wi...

C# Generic Methods

In my previous post, I explained about Generics. C# also provides Generic Methods. We can create a method which defer the parameter data type until the method is called. These parameters are called Type parameters that means we can pass the actual data type later. Below is the example of Generic Method. static void Swap<T>(ref T input1, ref T input2) { T temp =...
