Differences between constructor and destructor in C #

Put the object initialization work in the constructor, and put the cleanup work in the destructor. When an object is created, the constructor is automatically executed. When an object dies, the Destructor is automatically executed. In this way, you do not have to worry about the initialization and clearing of objects.

Destructor are controlled by the garbage collector.

 

The Destructor is controlled by the garbage collector. the initialization of the object is put in the constructor, And the cleanup is put in the destructor. When an object is created, the constructor is automatically executed. When an object dies, the Destructor is automatically executed. In this way, you do not have to worry about the initialization and clearing of objects. Do not define destructor. If you want to release unmanaged resources, let the class inherit the idisposable interface to implement the dispose mode.

 

The declared objects in using can be released. For more information, see the example.

 

Using System;

Namespace ConsoleApplication7
{
/** // <Summary>
/// Summary of test.
/// </Summary>
Public class Test: IDisposable
{
Public Test (string name)
{
This. name = name;
}

Private string name;

Public string Name
{
Get {return name ;}
Set {name = value ;}
}

Public static void main ()
{
Console. writeline ("programme start! ");

Test test1 = new test ("1 ");
Using (test1)
{
}
Using (Test test2 = new Test ("2"), test3 = new Test ("3 "))
{
Test test4 = new Test ("4 ");
}

Console. WriteLine ("Programme Over! ");
Console. ReadLine ();
}

Idisposable member # region idisposable Member

Public void dispose ()
{
Console. writeline ("{0} releasing resources", name );
}

# Endregion
}

}

This method is feasible.
