打开visual studio.net 2003,依次点击文件--新建--项目--控制台应用程序，语言选C#,在程序里增加以下方法，然后在main()函数里加入
System.Console.WriteLine("系统内存是："+GetPhisicalMemory().ToString());
--------------------------------------------------------
private int GetPhisicalMemory()
{
ManagementObjectSearcher searcher = new ManagementObjectSearcher(); //用于查询一些如系统信息的管理对象
searcher.Query = new SelectQuery("Win32_PhysicalMemory","",new string[]{"Capacity"});//设置查询条件
ManagementObjectCollection collection = searcher.Get(); //获取内存容量
ManagementObjectCollection.ManagementObjectEnumerator em = collection.GetEnumerator();
int capacity = 0;
while(em.MoveNext())
{
ManagementBaseObject baseObj = em.Current;
if(baseObj.Properties["Capacity"].Value != null)
{
try
{
capacity += int.Parse(baseObj.Properties["Capacity"].Value.ToString());
}
catch
{
MessageBox.Show("有错误发生！请联系软件作者！\n","错误信息",MessageBoxButtons.OK,MessageBoxIcon.Error,MessageBoxDefaultButton.Button1);
return 0;
}
}
}
return capacity;}
