Syntax

'Declaration
<ContentPropertyAttribute("Cases")> _
Public NotInheritable Class Switch _
    Inherits NativeActivity
'Usage
Dim instance As Switch

[ContentPropertyAttribute("Cases")]
public sealed class Switch : NativeActivity

[ContentPropertyAttribute(L"Cases")]
public ref class Switch sealed : public NativeActivity

public final class Switch extends NativeActivity

[<SealedAttribute>]
[<ContentPropertyAttribute("Cases")>]
type Switch =  
    class
        inherit NativeActivity
    end

Remarks

Each case in the Cases dictionary consists of a value (serving as the key for the dictionary) and an activity (serving as the value for the dictionary). The Expression is evaluated and compared against the values in the Cases dictionary. If a match is found, the corresponding activity is executed. Every key in the Cases dictionary must be unique according to the dictionary’s equality comparer.
