如何获得可用系统内存的大小？

Is it possible to get the size of system available memory in C#.NET? if yes how?

是否有可能在C＃.NET中获得系统可用内存的大小？如果有，怎么样？

5 个解决方案

Use Microsoft.VisualBasic.Devices.ComputerInfo.TotalPhysicalMemory.

使用Microsoft.VisualBasic.Devices.ComputerInfo.TotalPhysicalMemory。

Right-click your project, Add Reference, select Microsoft.VisualBasic.

右键单击项目“添加引用”，选择“Microsoft.VisualBasic”。

This answer is based on Hans Passant's. The required property is AvailablePhysicalMemory actually. and it (and TotalPhysicalMemory and others) are instance variables, so it should be

这个答案是基于Hans Passant的。实际所需的属性是AvailablePhysicalMemory。它（和TotalPhysicalMemory等）是实例变量，所以它应该是

new ComputerInfo().AvailablePhysicalMemory

It works in C#, but I wonder why this page says that for C#, "This language is not supported or no code example is available."

它适用于C＃，但我想知道为什么这个页面说C＃，“这种语言不受支持或者没有代码示例可用。”

You will need to add a reference to System.Management

您需要添加对System.Management的引用

using System;
using System.Management;

namespace MemInfo
{
    class Program
    {       
        static void Main(string[] args)
        {
            ObjectQuery winQuery = new ObjectQuery("SELECT * FROM Win32_LogicalMemoryConfiguration");

            ManagementObjectSearcher searcher = new ManagementObjectSearcher(winQuery);

            foreach (ManagementObject item in searcher.Get())
            {
                Console.WriteLine("Total Space = " + item["TotalPageFileSpace"]);
                Console.WriteLine("Total Physical Memory = " + item["TotalPhysicalMemory"]);
                Console.WriteLine("Total Virtual Memory = " + item["TotalVirtualMemory"]);
                Console.WriteLine("Available Virtual Memory = " + item["AvailableVirtualMemory"]);
            }
            Console.Read();
        }
    }
}

Output:

输出：

Total Space = 4033036

总空间= 4033036

Total Physical Memory = 2095172

总物理内存= 2095172

Total Virtual Memory = 1933904

总虚拟内存= 1933904

Available Virtual Memory = 116280

可用虚拟内存= 116280

var performance = new System.Diagnostics.PerformanceCounter("Memory", "Available MBytes");
var memory = performance.NextValue();

#5

Using the performance counters accessible via System.Diagnostics will be one option.

使用可通过System.Diagnostics访问的性能计数器将是一种选择。
