我有一个应用，我希望datagridview刷新每行5秒。我的代码运行良好，除非我发生内存泄漏，我想所有资源都没有释放...但是它是一个循环运行线程，我不想处理它...
我这样开始我的任务
Private Sub Desktop_Load(sender As Object, e As EventArgs) Handles Me.Load
Dim F As String = Main.UserDataFolder & "\Wemine4U\Config\MinerList.wemine"
If IO.File.Exists(F) = True Then
Dim NOF2 As Integer = FreeFile()
Dim texte2 As String
ListView1.Items.Clear()
FileOpen(NOF2, Main.UserDataFolder & "\Wemine4U\Config\MinerList.wemine", OpenMode.Input, OpenAccess.Read, OpenShare.Shared)
Do Until EOF(NOF2)
texte2 = LineInput(NOF2)
Main.DataMiner.Rows.Add(Split(texte2, Chr(9))(1).ToString, "0" + " C", "0.00", "0.00", "0", "0", "0", "0", "N/D", "N/D", Split(texte2, Chr(9))(3).ToString, "", "", "0")
Dim updatem As System.Threading.Thread
updatem = New Thread(AddressOf loadTableMiner)
updatem.Name = Split(texte2, Chr(9))(1) & Chr(9) & Split(texte2, Chr(9))(3)
updatem.IsBackground = True
updatem.Start()
Loop
FileClose(NOF2)
End If
DataGridView1.DataSource = DataSource
DataGridView1.Columns(11).Visible = False
DataGridView1.Columns(12).Visible = False
DataGridView1.Columns(13).Visible = False
End Sub
在我想要循环运行这样的线程之后

并且内存慢慢长大...我不知道为什么...有人知道我的代码有什么问题吗？
