Binaryworld - ConcatenateStrings - Concatenating an array of strings ... [ VB.net -> String ]

' Concatenate the input strings, and return the resulting string. The first
' input string is used as a separator.
'
' Example:
' Dim i As Integer = 4
' Dim d As Double = 34.45
' Dim s As String = "VB-2-The-Max"
' Dim ret As String = ConcatenateStrings(" ", s, "is a nice site, ins't it?",
' "It has been online for", i, "years.", "Just test the function with a Double
' now:", d)
' MessageBox.Show(ret)

Function ConcatenateStrings(ByVal sep As String, ByVal ParamArray args() As _
  Object) As String
  Dim builder As New System.Text.StringBuilder()
  ' add each item of the input array to the StringBuilder's string
  Dim o As Object
  For Each o In args
    If builder.Length > 0 Then
      ' add the separator if this is not the first item we add
      builder.Append(sep)
    End If
    builder.Append(o)
  Next
  ' return the final string
  Return builder.ToString()
End Function

' If all arguments are strings, then the following method is simpler and faster:

Function ConcatenateStrings2(ByVal sep As String, ByVal ParamArray args()
As String) As String
  Return String.Join(sep, args)
End Function
