In Visual Studio 2008 vb.net i have created a windows forms application containing 2 web references: wr1 and wr2.
wr1 contains a public class "Person" and wr2 also contains a public class "Person". They both have exactly the same properties.
What i would like to achieve is to convert an object of type wr1.person to wr2.person. Something like this:
dim p1 as wr1.person
p1 = wr1.GetPerson(123)
dim p2 as wr2.person
p2 = p1
wr2.AddPerson(p2)

I am using Linq to convert an array of any object to a CSV list:String.Join(",", (From item In objectArray Select item.ToString()).ToArray())
This is giving me the strange error: "Range variable name cannot match the name of a member of the 'Object' class."I can get round it by wrapping the string in a VB StrConv method, with a setting of "Nothing":String.Join(",", (From item In oArray Select StrConv(item.ToString(), VbStrConv.None)).ToArray())
However, this seems like a bit of a hack and I would like to avoid it.Does anyone have any ideas when this problems occurs, and any better ways to get round it?
in my project I use an Excel workbook as template. Right now, this workbook is located in the same directory as the exe-assembly and can be opened and manipulated by the user. To avoid this, I thought about adding the workbook to a ressource. That works. Problem: how can I convert the resulting byte-array/stream back to a workbook-object?I tried like this, but - obviously - the conversion fails:
Public Shared Sub test()
Dim wkb As Excel.Workbook
Dim bytes As Byte() = My.Resources.Template_1

I am looking for a way to convert my List(Of string) into an Object in vb. So in the end it would be the same as declaring Dim cArray() As Object = new Object. Can anyone point me to how i can achieve this? I cannot use the LINQ .ToArray as that creates a string array and this is not acceptable for my work. I need to pass this object into another one that has the parameter (aArray as Object).

wrote a procedure that accepts as input a parameter of type decimal, or type Long as well as an array type ar() as Boolean. First thing I will do in the procedure is establish just what type of parameter I received. No problem with the scalar types, I'll use the .GetType,determine whether it's Long of Decimal, and assign the parameter I just received to a variable of that type by using convert.toInt64 or convert.toDecimal, then do what I need to do. Not so if the parameter I received happens to be an array. .GetType will tell me what it is, for example returns "system.int64[]" if its an array of Longs, but then I fail to assign it to a variable for further processing as there appears to be no conversion method to do that.
