Created Unassigned: Adding host primitive types [49]

Dear Sir or Madam,
I need to be able to pass in primitive types.

I cannot use AddHostObject(). Calling AddHostObject() for boxed primitive types (double, int, etc.) raises exception "Invalid host item".

I cannot use AddRestrictedHostObject(). Although exception is not raised when using AddRestrictedHostObject(), however, the resulted value cannot be used within the script: any arithmetic operation results in NaN.

A workaround that I currently employed is to wrap the primitive type into a class or Array. I used Array successfully. However this is less convenient as a script writer would have to be aware of this. I wonder if it is possible to pass primitive types directly. Note that I cannot use 'engine.Script.p = 2.1' construct as parameters are added at run time and are not known during build.

I would perhaps have expected something like AddHostValue(), but could find any.

Sample script:
function foo()
{
string s;

try
{
double d = 2.1;
object paramValue = (object)d;
ScriptEngine engine = new JScriptEngine();
// exception is rasied:
engine.AddHostObject("p", paramValue);
// same exception is rasied: engine.AddHostObject("p", d);
// cannot do this: engine.Script.p = 2.1;
}
catch (Exception ex)
{
s = ex.Message;
}
}

Please help,
Yours faithfully
