iterating a list with ForEach

I have a list like this

Dim emailList as new List(Of String)
emailList.Add("[email protected]")
emailList.Add("[email protected]")
emaillist.Add("[email protected]")

How can I iterate the list with ForEach to get one string with the emails like this 

[email protected];[email protected];[email protected]

Dim emailList As New StringBuilder()

For Each (email As String In emails)
     emailList.Append(String.Format("{0};", email))
Next

Return emailList.ToString()

Forgive me if there are any syntax errors ... my VB.NET is a little rusty and I don't have a complier handy.

       Dim emailList As New List(Of String)
    emailList.Add("[email protected]")
    emailList.Add("[email protected]")
    emailList.Add("[email protected]")

    Dim output As StringBuilder = New StringBuilder
    For Each Email As String In emailList
        output.Append(IIf(String.IsNullOrEmpty(output.ToString), "", ";") & Email)
    Next

I wouldn't actually use a ForEach loop for this. Here is what I would do:

String.Join(";", emailList.ToArray());

You can try

Dim stringValue As String = String.Join(";", emailList.ToArray)

Have a look at String.Join Method

I'm not sure why you would want to use a foreach instead of a String.Join statement. You could simply String.Join() the list using a semi-colon as your joining character.

String.Join(";", emailList.ToArray())
