如何以编程方式获取(ASP).NET应用程序的总分配内存？

要以编程方式获取ASP.NET应用程序的总分配内存，您可以使用以下代码片段：

using System;
using System.Diagnostics;
using System.Runtime.InteropServices;

public class MemoryInfo
{
    [DllImport("kernel32.dll", SetLastError = true)]
    [return: MarshalAs(UnmanagedType.Bool)]
    static extern bool GetProcessMemoryInfo(IntPtr hProcess, out PROCESS_MEMORY_COUNTERS_EX counters, uint size);

    [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Auto)]
    public struct PROCESS_MEMORY_COUNTERS_EX
    {
        public uint cb;
        public uint PageFaultCount;
        public UIntPtr PeakWorkingSetSize;
        public UIntPtr WorkingSetSize;
        public UIntPtr QuotaPeakPagedPoolUsage;
        public UIntPtr QuotaPagedPoolUsage;
        public UIntPtr QuotaPeakNonPagedPoolUsage;
        public UIntPtr QuotaNonPagedPoolUsage;
        public UIntPtr PagefileUsage;
        public UIntPtr PeakPagefileUsage;
        public UIntPtr PrivateUsage;
    }

    public static ulong GetTotalAllocatedMemory()
    {
        var process = Process.GetCurrentProcess();
        var processHandle = process.Handle;
        var counters = new PROCESS_MEMORY_COUNTERS_EX();
        GetProcessMemoryInfo(processHandle, out counters, (uint)Marshal.SizeOf(counters));
        return (ulong)counters.PrivateUsage;
    }
}

这段代码定义了一个名为MemoryInfo的类，其中包含一个名为GetTotalAllocatedMemory的静态方法，该方法返回ASP.NET应用程序的总分配内存。

在这个方法中，我们首先获取当前进程的句柄，然后使用GetProcessMemoryInfo方法获取进程内存信息。最后，我们返回PrivateUsage字段的值，该值表示进程的总分配内存。

要使用此代码片段，只需在您的ASP.NET应用程序中调用MemoryInfo.GetTotalAllocatedMemory()方法即可。
