'Assign the Security GroupName from File to the String
Dim NewSecurityGroupName As String = line
Dim objGroupInfo1 As GroupInfo = BRApi.Security.Admin.GetGroup(si, NewSecurityGroupName)
If Not objGroupInfo1 Is Nothing Then
'Create a Object for Class Group
Dim objGroup As Group = New Group()
objGroup.Name = NewSecurityGroupName
'Create a Object for Class GroupInfo
Dim objGroupInfo As GroupInfo = New GroupInfo()
objGroupInfo.Group = objGroup
'Check the Group Already Exists
'BRApi.Security.Admin.SaveGroup(si, objGroupInfo, False, Nothing, TriStateBool.TrueValue)
BRApi.Security.Admin.DeleteGroup(si,NewSecurityGroupName)
BRApi.ErrorLog.LogMessage(si,NewSecurityGroupName & " " & "Group Deleted")
End If
