What is the use of Using Statement

Answer:

Using statement is used similar to finally block that is to dispose the object.
It declares that you are using a disposable object for a short period of time.
Once the using block ends,the CLR releases the corresponding object immediately by calling its dispose() method.

Example:

//Write code to allocate some resource

//List the allocated resource in a comma-separated list inside

//the parenthesis of the using block



using(...)

{

//use the allocated resource

}



//Here dispose() method is called for all the object referenced without writing any additional code.
