There are many times when I need to convert an array to a delimited string. Here is an easy way to do it using generics in .NET 2.0.
Public Shared Function ConvertArrayToString(Of arrayType As {IEnumerable})(ByVal array As arrayType(), ByVal separator As Char) As String
If Not IsValidArray(array) Then
Throw New ArgumentNullException("array")
End If
If IsNothing(separator) Then
Throw New ArgumentNullException("separator")
Dim result As New System.Text.StringBuilder
For Each arrayItem As arrayType In array
If result.Length > 0 Then
result.Append(separator)
result.Append(arrayItem.ToString)
Next
Return result.ToString
End Function
