Purpose

Using this Code Provider , you can easily make any class disposable. This Code Provider adds the IDisposable implementation along with all required methods (Dispose() and other optional methods) to the class.

Availability

It is available when the caret is in a class declaration.

Usage

1. Place the caret in a class declaration.

2. Press the Ctrl + . or Ctrl + ~ shortcut to invoke the Code Actions menu.

3. Select Implement IDisposable from the menu.

4. Select the members to dispose of using the mouse or Space key.

5. Optionally, open the Options menu using the Ctrl key.

6. Hit Enter to confirm the members’ selection.

After execution, the Code Provider implements the IDisposable interface and adds a common implementation of the required overloads.

Assuming that you have all available members selected ( S1 and S2 ) and left all options disabled, the following code is generated:

• C#
• VB.NET

public class DisposableClass : IDisposable {
    public Stream S1;
    public Stream S2 { get; set; }
    public void Dispose() {
        S1.Dispose();
        S2.Dispose();
    }
}

Public Class DisposableClass
    Implements IDisposable
    Public S1 As Stream
    Public Property S2() As Stream
    Public Sub Dispose() Implements IDisposable.Dispose
        S1.Dispose()
        S2.Dispose()
    End Sub
End Class

Options

Use the Options menu to configure the Code Provider.

You can change the following parameters by hitting the corresponding Key or by using your mouse:

Fields can be null

Key: N

Check this option if the fields or properties for which you are going to define the dispose pattern are null. If this option is selected, the members are checked for null before being disposed of.

Type can be inheritable

Key: I

Check this option to create another protected virtual Dispose method accepting a boolean parameter, which allows you to disable the actual disposing.

Type contains unmanaged resources

Key: U

Check this option to create the ReleaseUnmanagedResources method and the destructor that calls ReleaseUnmanagedResources and optionally calls Dispose.
