# MyObject. cs


Using System;



Namespace MyProjects


{


Public class MyObject: IDisposable


{


Public MyObject ()


{


}



Public void Dispose ()


{


// Dispose


Console. WriteLine ("Disposed ");


//...


}


}


}



# Class1.cs


Using System;



Namespace MyProjects


{


Public class Class1


{


Public Class1 ()


{


}



Public static void Main (string [] args)


{


Using (MyObject myObject = new MyObject ())


{


Console. WriteLine ("quit ");


}


}


}


}



Using will automatically call the Dispose method of MyObject.


If MyObject does not implement the IDispose interface, an error occurs during compilation: The type "MyProjects. MyObject" cannot be implicitly converted to "System. IDisposable"


This writing method can replace


Try


{//...}


Catch


{}


Finnaly


{MyObject. Dispose ();}
