converting an arraylist to an array...

[ultimia]

i'm somewhat new to vb, but i am writing this code using vb.net and in the process of learning stumbled across an arraylist

i tried converting the arraylist to an array using

dim a as array
a = mailbody.toarray()

and then attempted to print out the array on a email

message.body = string.join(vbnewline, a)

somehow this code isn't working and i can't figure out how, any help would be gladly appreciated ^^

What's not working about it? Some sort of run time error, or a compile error?

well heres the whole code, but i'm not sure how to put it in vb format on this forum... <-- newbie

and when i debug it gives me a system.invaldidcastexception


Public Sub sender(ByRef mailbody As ArrayList)
Dim a As Array
Dim message As System.Web.Mail.MailMessage = New System.Web.Mail.MailMessage
Dim NumberEmail As Integer
'Dim errorlinenumber As Integer
Try
For NumberEmail = 1 To projectnum - 1
'message.To = "[email protected]"
message.To = fformstorage(NumberEmail)
message.From = "[email protected]"
'note to self: edit sender line later
'i'm not sure what the server is called yet so i'm calling it "server" for now
message.Subject = "code error"
message.BodyFormat = MailFormat.Text
'all this other commented out material are here just for test/debugging purposes only
'message.Body = ("wow IT WORKED!")
'For errorlinenumber = 1 To sp.stringnumber
a = mailbody.ToArray()
message.Body = String.Join(vbNewLine, a)
Try
'SmtpMail.SmtpServer = "server"
SmtpMail.Send(message)
Catch ehttp As System.Web.HttpException
Console.WriteLine(ehttp.Message)
Console.WriteLine("Here is the full error message")
Console.Write(ehttp.ToString())
End Try
Next
Catch e As System.Exception
'display text of uknown error
Console.WriteLine("unknown exception occured ", e.Message)
Console.WriteLine("Here is the full error message")
Console.WriteLine(e.ToString())

End Try

End Sub

I assume this is falling over at the

a = mailbody.ToArray()

line...?

If so, try this:-

mailbody.CopyTo(a)

Let me know how you get on...

Hi,

Click on the "faq" tag at the top of the forum and go to the third section for full formatting instructions.

i thought i'd post this to help you with another vb.net feature:

you have a comment that says 'note to self:edit sender line later

you can use a 'token' to mark this in your TASKS. try this:

'todo edit sender line later

this will make it show up in your task view and you can double click on that task and go straight to that comment. no more searching for buried comments

wow thanks guys for the tips and advice. I ended up doing

a = mailbody.ToArray(Type.GetType("System.String"))
message.Body = String.Join(vbNewLine, a)

and got it through that way. Thanks for the advice though ^^
