大俠們,do me a favor!很急。。。
vb.net我在本機上編譯的時候ok的，可以在別的服務器上就出錯，錯誤描述如下：
代碼部分：
注：1174 line不註釋的話也是一樣哦！
Line 1170: Dim mail As MailMessage = New MailMessage
Line 1171: Dim sqlstr As String
Line 1172: Dim age As Integer = Left(FormatDateTime(Date.Today, DateFormat.GeneralDate), 4) - LstBirthY.SelectedValue
Line 1173: Dim dbclass As DataAccess = New DataAccess
Line 1174: 'Dim edate As Date = Date.Today

[解决办法]
看样子好象你只需要用年份，那就用
Date.Today.Year
吧
另外，Integer.Parse( string ) 正确执行的前提是你必须保证 string 是有效格式（可正确转换为 Integer）
[解决办法]
需要SMTP的配置
