What is the use of ‘using’ statement in C#?

The ‘using’ block is used to obtain a resource and process it and then automatically dispose of when the execution of the block completed.

In simple words, The reason for the using statement is to ensure that the object is disposed of as soon as it goes out of scope, and it doesn’t require explicit code to ensure that this happens.

Example,

using (MyResource myRes = new MyResource())
{
    myRes.DoSomething();
}
