vj#: A property in C# is having System.Security.Permissions.PermissionSet Attribute. When I try to convert the same with same permissionset attribute in VJ#, the code does not compile saying that "Attribute 'System.Security.Permissions.PermissionSetAttribute' is not valid on this declaration"

Following is the property written in C#
public override string Tex

[System.Security.Permissions.PermissionSet(System.Security.Permissions.SecurityAction.Demand, Name="FullTrust")]
ge

return _text

[System.Security.Permissions.PermissionSet(System.Security.Permissions.SecurityAction.Demand, Name="FullTrust")]
se

_text = value



And following is its conversion into equivalent VJ# code
/** @property(
*
/** @attribute System.Security.Permissions.PermissionSet
System.Security.Permissions.SecurityAction.Demand, Name = "FullTrust"
*
public String get_Text(

return _text
}

/** @property(
*
/** @attribute System.Security.Permissions.PermissionSet
System.Security.Permissions.SecurityAction.Demand, Name = "FullTrust"
*
public void set_Text(String value

_text = value
}

If I remove the attribute declaration it compiles and executes fine and the output matches with the C# output. But logically is it alright to remove the permissionset attribute declaration? Will it affect the meaning of the code
Please reply if anybody knows i

I don't think it will change anything. J# must run with "FullTrust" anyway.

The syntax you used is for attaching the attribute on the accessor method
not on the property. For example:

Attaching on the accessor:

public override string Text
{

[System.Security.Permissions.PermissionSet(System.Security.Permissions.Secur
ityAction.Demand, Name="FullTrust")]
get
{
return _text;
}
}

Attaching on the property itself. This gives an error:

[System.Security.Permissions.PermissionSet(System.Security.Permissions.Secur
ityAction.Demand, Name="FullTrust")]
public override string Text
{

[System.Security.Permissions.PermissionSet(System.Security.Permissions.Secur
ityAction.Demand, Name="FullTrust")]
get
{
return _text;
}
}

The same can be achieved in J# too. The sample code that is posted is:

** @property()
*/
/** @attribute System.Security.Permissions.PermissionSet(
System.Security.Permissions.SecurityAction.Demand, Name =
"FullTrust")
*/
public String get_Text()
{
return _text;
}


This attaches the attribute on the property itself hence the error. To
attach on the accessor, use @attribute.method

** @property()
*/
/** @attribute.method System.Security.Permissions.PermissionSet(
System.Security.Permissions.SecurityAction.Demand, Name =
"FullTrust")
*/
public String get_Text()
{
return _text;
}
