int loop1;
 HttpFileCollection MyFileColl = Request.Files;

 for( loop1 = 0; loop1 < MyFileColl.Count; loop1++)
 {
    if( MyFileColl.GetKey(loop1) == "CustInfo")
    {
       //...
    }
 }

Dim loop1 As Integer
 Dim MyFileColl As HttpFileCollection = Request.Files
 
 For loop1 = 0 To MyFileColl.Count - 1
    If MyFileColl.GetKey(loop1) = "CustInfo" Then
       '...
    End If
 Next loop1
