SetProcessWorkingSetSize减少内存占用

[DllImport("kernel32.dll", EntryPoint = "SetProcessWorkingSetSize")]
public static extern int SetProcessWorkingSetSize(IntPtr process, int minSize, int maxSize);

/// <summary>
/// 释放内存
/// </summary>
public static void ClearMemory()
{
     GC.Collect();
     GC.WaitForPendingFinalizers();
     if (Environment.OSVersion.Platform == PlatformID.Win32NT)
     {
         SetProcessWorkingSetSize(Process.GetCurrentProcess().Handle, -1, -1);
     }
}

如何获取当前应用占用的内存大小:

/// <summary> /// 释放内存 /// </summary> public static void ClearMemory() {     //获得当前工作进程     Process proc = Process.GetCurrentProcess();     long usedMemory = proc.PrivateMemorySize64;     if (usedMemory > 1024 * 1024 * 20)     {         GC.Collect();         GC.WaitForPendingFinalizers();         if (Environment.OSVersion.Platform == PlatformID.Win32NT)         {             SetProcessWorkingSetSize(Process.GetCurrentProcess().Handle, -1, -1);         }     } }
