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);
}
}
