Dynamically creating type of System.Int32, how??

[Søren M. Olesen]

Hi

How do I dynamically create a type of System.Int32 with the value 123?? I've tried the following:

Dim keyci As ConstructorInfo = Type.GetType("S ystem.Int32").G etConstructor(N ew Type() {Type.GetType(" System.Int32")} )
Dim key As Object = keyci.Invoke(Ne w Object() {"123"})


however it doesn't seem to work....

TIA

.... because 'Int32' doesn't have a parameterized constructor.

I kind of figured that, but is there a way to do it, or do I have to use a
select case and then cast on the type??

Re: Dynamically creating type of System.Int32, how??

Søren,
It appears you simply want to convert a String to an arbitrary type.

Have you considered Convert.ChangeT ype?

Something like:

Dim key As Object = Convert.ChangeT ype("123",
Type.GetType("S ystem.Int32"))

Where the GetType changes based on outside criteria.

However if you know you will always be using Int32, then a simply cast is
easier:

Either of the following:
key = CInt("123")
key = Convert.ToInt32 ("123")


Hope this helps
Jay
