Type Conversion

[Alphonse Giambrone]

How can I convert a string to a different type based on another string or
other variable?

For instance, instead of
Dim i as Integer

i = ctype("1000", Integer)

I would like to do

Dim i as Integer

i = ctype("1000","I nteger")

In other words the type conversion would be done programmaticall y, rather
than specified in the code.

In old VB the 'types' had values (like Integer =3, Long = 4, etc). Is there
something similar in .NET?

TIA

use a switch() statement and ctype() accordingly

Alphonse,

You could do this:

Dim i As Integer = CType("1000", System.Type.Get Type("System.In t32"))

Where:
System.Type.Get Type([Type Name As String])

Your question doesn't make sense as stated. What exactly are you trying to
accomplish? What is your requirement?

Thanks, that would work, but I thought there should be a more compact way.
It is really not a necessity, just that I feel I am missing something.

Thanks Justin,

That is the type of statement I am looking for, but it does not work.
Error is, System.Type.Get Type is undefined.

Sorry for the confusion, Kevin.
I know there are other ways to do this, but it is bugging me now.
Simplistically, I want to have a database table with 3 fields.
ItemField (text)
ValueField (text)
TypeField (could be integer, text or whatever is necessary)

ItemField would contain the description of a value to lookup (for example
"LastDatabaseCo mpact").
ValueField would contain the associated value as a string (for example
"1/4/2004").
TypeField would indicate the type of data in ValueField.

I would then have a function that could look up the value in ValueField for
the requested ItemField and return the result as the appropriate type. In
this example a date.
Skipping all the db connectivity, etc.
It would be something like
Return Ctype(ValueFiel d, TypeField) '(this obviously would not work as
is).

Hi Alphonse,

You are getting an object is undefined error because CType does not allow
variables or calculations within the type parameter. The Visual Basic
Language Reference - CType Function documentation shows this:

typename
Any expression that is legal within an As clause in a Dim statement, that
is, the name of any data type, object, structure, class, or interface.

We are not allowed to dim a variable as type System.Type.Get Type(...). The
same thing applies to the type parameter of the CType function.

I think you need to use a Select Case statement, as mentioned earlier.

Thank you, Mike
