打开 Winform 窗口后，内存一直增加，关闭窗口后，内存不会还原，使用Dispose();没有效果
比如第一段代码中使用 Winform 显示图片
另外找到 .NET API 中，GC.Collect();和SetProcessWorkingSetSize函数，会降低内存显示，实际上是转移到虚拟内存中，效果非常不好
是否有好的办法关闭 form 窗口后，清理内存的呢
var Forms = forms.System.Windows.Forms; var form = new Forms.Form; form.StartPosition = Forms.FormStartPosition.Manual; form.FormBorderStyle = Forms.FormBorderStyle.None; form.TopMost = true; form.COntrolBox= false; form.ShowInTaskbar = false; form.Margin = new Forms.Padding(0); form.Padding = new Forms.Padding(1); form.MinimumSize = new Size(10, 10); form.Size = new Size(10, 10); form.Location = new Point(100, 100); form.AutoSize = true; form.GetType().GetProperty("DoubleBuffered", host.flags(clr.System.Reflection.BindingFlags.NonPublic, clr.System.Reflection.BindingFlags.Instance)) .SetValue(form, true); form.BackColor = drawing.System.Drawing.SystemColors.HotTrack; var pic = new Forms.PictureBox; pic.Name = 'pic'; pic.SizeMode = Forms.PictureBoxSizeMode.Zoom; pic.Size = new Size(450, 500); pic.BackColor = drawing.System.Drawing.SystemColors.Control; pic.Location = new Point(0, 0); pic.Image = img; form.Controls.Add(pic); var autoSize = form.Size; var t = (form.ClientSize.Width - pic.Width - form.Padding.Horizontal); autoSize.Width -= t; autoSize.Height -= t; form.AutoSize = false; form.Size = autoSize; pic.Dock = Forms.DockStyle.Fill; var form_shown = form.Shown.connect( function (sender, args) { form.TopMost = true; form.Activate(); }); var pic_doubleClick = pic.DoubleClick.connect( function (sender, args) { form.Dispose(); pic.Dispose(); Forms.Application.Exit(); form.Close(); }); Forms.Application.Run(form); img.Dispose(); 使用SetProcessWorkingSetSize
form.Close(); FlushMemory(); function FlushMemory() { System.GC.Collect(); System.GC.WaitForPendingFinalizers(); if (System.Environment.OSVersion.Platform == System.PlatformID.Win32NT) SetProcessWorkingSetSize(System.Diagnostics.Process.GetCurrentProcess().Handle, -1, -1); }
