检查你代码中所有定义了  Dim g As Graphics 的地方

是否都配对了g.Dispose()

目测有两处没有配对，内存不能及时释放。

类似的这种代码有问题，频繁的增加，不消除就会占用资源。

你项目有两处要改。

Dim p As WinForm.Painter =e.Form.CreateControl("p", ControlTypeEnum.Painter)
p.Width = zwidth \'原始照片宽动态赋给画板宽
p.Height = zheight \'原始照片高动态赋给画板高
Dim g As Graphics = p.Graphics
g.Clear(Color.White)
g.DrawImage(getImage(route),0,0,zwidth,zheight)
g.DrawImage(bar.GetImage,(zwidth-200),(zheight-680),150,150)
Dim rm As New prt.RenderImage \'定义一个图片对象
rm.Image = GetImage("archives.ico") \'设置图片
rm.Style.ImageAlign.StretchHorz = True \'水平拉伸
g.DrawImage(rm.Image,(zwidth-75),(zheight-85),30,30)
Dim fnt As New Font("黑体",20,FontStyle.Bold) \'黑体,10号,加粗
g.DrawString(fn,fnt,Brushes.Aqua,(zwidth-250),(zheight-35))
p.Repaint()
Dim img As Image = p.Image
p.Save(route2)
img.save(route2)

改成

Dim p As WinForm.Painter =e.Form.CreateControl("p", ControlTypeEnum.Painter)
For Each r As DataRow In DataTables("newtrj").Select("id>1")   \'从数据表中提取数据
    bar.Code = r("qrcord")
    Dim fn As String = ""
    fn = r("cn_name")
    If fn <> "" And filesys.FileExists("d:\\as\\" & fn & ".jpg") = True Then
        Dim route As String = "d:\\as\\" & fn & ".jpg" \'原始照片存放路径
        Dim route2 As String ="d:\\qrcord\\" & fn & ".jpg"
        Dim zwidth = getImage(route).width \'原始照片宽
        Dim zheight = getImage(route).height \'原始照片高
       
        p.Width = zwidth \'原始照片宽动态赋给画板宽
        p.Height = zheight \'原始照片高动态赋给画板高
        Dim g As Graphics = p.Graphics
        g.Clear(Color.White)
        g.DrawImage(getImage(route),0,0,zwidth,zheight)
        g.DrawImage(bar.GetImage,(zwidth-200),(zheight-680),150,150)
        Dim rm As New prt.RenderImage \'定义一个图片对象
        rm.Image = GetImage("archives.ico") \'设置图片
        rm.Style.ImageAlign.StretchHorz = True \'水平拉伸
        g.DrawImage(rm.Image,(zwidth-75),(zheight-85),30,30)
        Dim fnt As New Font("黑体",20,FontStyle.Bold) \'黑体,10号,加粗
        g.DrawString(fn,fnt,Brushes.Aqua,(zwidth-250),(zheight-35))
        p.Repaint()
        Dim img As Image = p.Image
        p.Save(route2)
        img.save(route2)
    End If
Next
e.Form.RemoveControl("p")
