如何从Win32处理器获取处理器ID

问题描述

string strProcessorId = string.Empty;
SelectQuery query = new SelectQuery("Win32_processor");
ManagementObjectSearcher search = new ManagementObjectSearcher(query);

foreach (ManagementObject info in search.Get())
{
    strProcessorId = info["processorId"].ToString();
}
Console.WriteLine(strProcessorId);
Console.ReadLine();

它给出了行错误

strProcessorId = info["processorId"].ToString();

错误是：对象引用未设置为对象的实例。

如何清除此错误

推荐答案

尝试

    string strProcessorId = string.Empty;
    SelectQuery query = new SelectQuery("Win32_processor");
    ManagementObjectSearcher search = new ManagementObjectSearcher(query);

    foreach (ManagementObject info in search.Get())
    {
        strProcessorId = info["ProcessorID"].ToString();
    }
    Console.WriteLine(strProcessorId);
    Console.ReadLine();

认为只是缺少资本意味着返回了空值

think it was just the capital missing that meant a null was being returned
