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(G etPropertyValue (oCustomer,prop name)) <-- returns
oCustomer.First Name

Hi,
Check out System.Type.Inv okeMember()

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

http://msdn.microsoft.com/library/de...mefunction.asp

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

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

Dim properties As System.Componen tModel.Property DescriptorColle ction
properties =
System.Componen tModel.TypeDesc riptor.GetPrope rties(oCustomer )
Dim value As Object = properties("Fir stName").GetVal ue(oCustomer)

Hope this helps

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