如何釋放內存：
1 [DllImport("kernel32.dll", EntryPoint = "SetProcessWorkingSetSize")] 2 public static extern int SetProcessWorkingSetSize(IntPtr process, int minSize, int maxSize); 3
4 /// <summary>
5 /// 釋放內存 6 /// </summary>
7 public static void ClearMemory() 8 { 9 GC.Collect(); 10 GC.WaitForPendingFinalizers(); 11 if (Environment.OSVersion.Platform == PlatformID.Win32NT) 12 { 13 SetProcessWorkingSetSize(Process.GetCurrentProcess().Handle, -1, -1); 14 } 15 }
如何獲取當前應用占用的內存大小：
1 /// <summary>
2 /// 釋放內存 3 /// </summary>
4 public static void ClearMemory() 5 { 6 //獲得當前工作進程
7 Process proc = Process.GetCurrentProcess(); 8 long usedMemory = proc.PrivateMemorySize64; 9 if (usedMemory > 1024 * 1024 * 20) 10 { 11 GC.Collect(); 12 GC.WaitForPendingFinalizers(); 13 if (Environment.OSVersion.Platform == PlatformID.Win32NT) 14 { 15 SetProcessWorkingSetSize(Process.GetCurrentProcess().Handle, -1, -1); 16 } 17 } 18 }
