Use the using operator in C #

Isn't the using operator in C # used by many people? Don't even know?
In fact, this operator is very useful in small places.

String 8

 

According to the msdn explanation
Http://msdn2.microsoft.com/zh-CN/library/yh598w02 (vs.80). aspx
The using keyword is also used to create using statements. This type of statement defines when the object string 8 will be released.

For example
Class Demo: idisposable
{
Public void dispose ()
{
Console. writeline ("dispose ");
} String 6

Public void demomethod ()
{
Console. writeline ("hi ");
}
}; String 9

Using (demo a = new demo ())
{
A. demomethod ();
}
We can see that the dispose () method will be executed at the same time, which makes the convenience self-evident.

String 4
