winform中如果每次打开的窗体都是通过new出来的,发现几次过后就会出现提示”内存不足“问题,那么在关闭窗体的时候怎么处理可以及时释放内存?dispose方法可能也无法解决这个问题。我们可以每次在关闭窗体的时候刷新存储器来彻底释放内存。
using System;using System.Collections.Generic;using System.Diagnostics;using System.Drawing;using System.IO;using System.Runtime.InteropServices;using System.Windows.Forms;[DllImport("kernel32.dll")]private static extern bool SetProcessWorkingSetSize(IntPtr process, int minSize, int maxSize);//关闭窗体按钮 private void btnReturn_Click(object sender, EventArgs e){ this.Close(); FlushMemory();}//刷新存储器private static void FlushMemory(){ GC.Collect(); GC.WaitForPendingFinalizers(); if (Environment.OSVersion.Platform == PlatformID.Win32NT) { SetProcessWorkingSetSize(Process.GetCurrentProcess().Handle, -1, -1); } }
