Access Construct

===Access Construct===
The access construct can be added to a property or method declaration making the [dynamic access modifier|access modifier dynamic].  That is a method's or property's access modifier (whether it is private or public) can  change depending on role of the [login|logged in user].

For example 'MyMethod' will be 'public' when the [login|logged in user] has the [role] 'MyRole'.  When the logged in user does not have the role 'MyRole' then the method 'MyMethod' will be private.

Note: ''The access modifier changes the run time appearance of the property or the method, not whether a property or method is public or private at compile time.  This means that other code can still use a method or property.  Only at run time, when the method or property is called, will access roles be checked against the [login|login user] roles.''

((({{
public void MyMethod() :access(MyRole){br}
{ {br}
...{br}
}{br}
}})))
The access construct can also be used with properties.

((({{
public void MyProperty:access(MyRole){br}
{ {br}
:   get;{br}
:  set;{br}
}{br}
}})))
In the this example the property can be set if [login|logged in user] has the 
role of "MyRole".

((({{
public void MyProperty{br}
{ {br}
:   get;{br}
:  set:access(MyRole);{br}
}{br}
}})))
Note: ''The access construct can not be used to assign roles to a workflow object.  Workflow objects must have [role#rolesToworkflowprogrammatically|roles assigned programmatically].''

The access construct can also use a boolean property as parameter.   See [http://jetfire.codeplex.com/Wiki/View.aspx?title=Controling%20when%20a%20Method%20or%20Property%20can%20be%20called&amp;referringTitle=C-Sharp%20Examples|Basket Example (Controlling when a method can be called)]
