我尝试每隔30秒将临时目录保存为临时目录，但每次只能保存一次

Question

我尝试每隔30秒将临时目录保存为临时目录，但每个目录只保存一次，给我一个错误 这是我的错误

A generic error occurred in GDI+. 

堆栈跟踪

at System.Drawing.Image.Save(String filename, ImageCodecInfo encoder, EncoderParameters encoderParams) 

在System.Drawing.Image.Save（字符串文件名，格式的imageformat） 在WindowsApplication1.Form1.savetempfoto（）在Form1中.vb：line 372

而行的错误是

PB1.Save(path, System.Drawing.Imaging.ImageFormat.Bmp) 

这是我的代码

Public Function temdirx() 
    My.Computer.FileSystem.CreateDirectory(tempdir) 
End Function 


Public Function timesavetemp() 
    Timer2.Start() 

End Function 

Private Sub Timer2_Tick(sender As Object, e As EventArgs) Handles Timer2.Tick 
    timetosavetemp = timetosavetemp + 1 

    If timetosavetemp >= 30 Then 
     savetempfoto() 
     timetosavetemp = 0 

    End If 
End Sub 
Public Function savetempfoto() 
    Dim PB1 As New Bitmap(PictureBox1.Image) 
    'Dim frame As Long 'individual frames 
    'Dim strings As String 

    'strings = frame 
    'Dim path As String = String.Format("C:\Mediamemebuilderpro\MDAL1Image{0}.jpg", nametosave) 
    'PB1.Save(path, System.Drawing.Imaging.ImageFormat.Bmp) 
    'PB1.Save("C:\Mediamemebuilderpro\MDAL1Image" & strings & ".jpg", System.Drawing.Imaging.ImageFormat.Bmp) 
    'frame += 1 
    Dim filename As String = "MDAL1Image" 'Change as needed 
    Dim path As String = String.Format("C:\Mediamemebuilderpro\{0}{1}.jpg", filename, nametosave) 
    PB1.Save(path, System.Drawing.Imaging.ImageFormat.Bmp) 
    timetosavetemp = 0 
End Function 
Private Sub Button5_Click(sender As Object, e As EventArgs) Handles Button5.Click 
    For Each file As String In IO.Directory.GetFiles("C:\Mediamemebuilderpro", "*.*") 

     ListBox1.Items.Add(file) 

    Next 
End Sub 

Private Sub Button20_Click(sender As Object, e As EventArgs) Handles Button20.Click 
    ListBox1.Items.Clear() 

End Sub

有任何原因，你为什么会得到这个错误。通常

Saving image: A generic error occurred in GDI+. (vb.net)

次它的东西很简单：从这里开始。
