Accessing a property using a string containing the property name?

[Don]

Is it possible to access the property of an object using a string containing
the name of the property you want to access? Something like:

oCustomer = New Customer
propname = "FirstName"
Console.Write(GetPropertyValue(oCustomer,propname)) <-- returns
oCustomer.FirstName

Hi,
Check out System.Type.InvokeMember()

Is it possible to access the property of an object using a string containing
the name of the property you want to access? Something like:

oCustomer = New Customer
propname = "FirstName"
Console.Write(GetPropertyValue(oCustomer,propname)) <-- returns
oCustomer.FirstName

Don,
In addition to System.Type.InvokeMember, I find CallByName to be a handy
wrapper for System.Type.InvokeMember.

http://msdn.microsoft.com/library/d.../en-us/vblr7/html/vafctcallbynamefunction.asp

Dim value As Object = CallByName(oCustomer, "FirstName",
CallType.Get)

Also I've used TypeDescriptor.GetProperties with much success.

Dim properties As System.ComponentModel.PropertyDescriptorCollection
properties =
System.ComponentModel.TypeDescriptor.GetProperties(oCustomer)
Dim value As Object = properties("FirstName").GetValue(oCustomer)

Hope this helps
Jay

CallByName is, by far, the simplest of the bunch and wholly adequate for my
needs. Thanks to everyone who responded (and so quickly!)
