When you open the TV you will find a bunch of LED lights that are covered with plastic reflectors or lenses. Usually, they fall off due to the poor quality or the heat that is created inside the TV. These reflectors are placed in front of the LED backlight and are used to spread the LED light on the screen. So What Causes White Spots or Dots on TV Screen? White spots or dots on LCD TV are a result of a fallen reflector (lens) inside the LCD TV panel. What Causes White Spots or Dots on TV Screen?

What Causes White Spots or Dots on TV Screen?.In the third approach, we need to project the required properties into a new anonymous type, which already overrides the Equals() and GetHashCode() methodsĪpproach1: Implementing IEqualit圜omparer interfaceĬreate a class file with the name StudentComparer.cs and then implement the IEqualit圜omparer interface as shown below.In the second approach, we need to override the Equals() and GetHashCode() methods within the Student class itself. So here we will create a class that implements the IEqualit圜omparer interface and then we need to pass that compare instance to the Distinct() method. We need to use the other overloaded version of the Distinct() method which takes the IEqualit圜omparer interface as an argument.We can solve the above problem in four different ways. This is because the default comparer which is used for comparison is only checked whether two object references are equal and not the individual property values of the complex object. Now execute the query and see the output.Īs you can see, it will not select distinct students rather it select all the students. Here we have a string array of names and we need to return the distinct names from the collection. Note: In query syntax, there is no such operator call distinct, so here we need to use both query and method syntax to achieve the same. The following program shows how to get the distinct integer values using both Method and Query syntax: using System Our requirement is to fetch remove the duplicate values and return only the distinct values as shown below. Here we have an integer collection that contains duplicate integer values. Example1: LINQ Distinct Method on Value Type If this is not clear at the moment, don’t worry we will cover the use of the Comparer in this article also. The one and the only difference between these two methods is the second overloaded version takes an IEqualit圜omparer as input which means the Distinct Operator can also be used with Comparer also. There are two overloaded versions available for the Distinct Method as shown below. The LINQ Distinct Method in C# is used to return the distinct elements from a single data source.
