i am trying to increment string value by 1 after converting it into int type.
but it is concatenating string value not number.

```
Mail(email, "SUB", "Test body.:" + lbloText.InnerText + lblame.InnerText + lblNo.InnerText + "  with Revision:" + Convert.ToInt32( lblRevision.InnerText )+1 + " Has ben genrated");

```

in the above i am trying to increment lblRevision.InnerText by 1 after converting it into int but it concates as string value is not incrementing.
Any idea would be appreciated.
