关于数据接口咨询
Imports System.Data
Imports System.Data.SqlClient
Imports System.ComponentModel

Public Class DataBase
Implements IDisposable
Private SqlConn As SqlConnection
Public Shared sConn As String = "Persist Security Info=False;Integrated Security=SSPI;database=hrmbook;server=localhost;Connect Timeout=30 "
Public Sub Dispose() Implements System.IDisposable.Dispose
Dispose(True)
GC.SuppressFinalize(True)
End Sub
Protected Sub Dispose(ByVal disposing As Boolean)
If disposing <> True Then
Return
End If
If SqlConn Is Nothing = False Then
SqlConn.Dispose()
SqlConn = Nothing
End If
End Sub
End Class
才开始学vb.net上面这句不是太理解，希望那位大哥大姐帮忙解释解释
Implements IDisposable ？
GC.SuppressFinalize(True) ？

Implements IDisposable 意思是
DataBase类实现接口 IDisposable
GC.SuppressFinalize(True) 是垃圾回收的意思
