C#实现获取电脑硬件显卡信息的示例代码

// 获取显卡信息
ManagementObjectSearcher searcher1 = new ManagementObjectSearcher("SELECT * FROM Win32_VideoController");
foreach (ManagementObject queryObj in searcher1.Get())
{
    textBox1.AppendText($"显卡名称: {queryObj["Name"]}\r\n");
    textBox1.AppendText($"显存大小（字节）: {queryObj["AdapterRAM"]}\r\n");
    textBox1.AppendText($"驱动程序版本: {queryObj["DriverVersion"]}\r\n");
}

// 输出所有显卡字段信息
var scope = new ManagementScope("\\\\.\\ROOT\\CIMV2");
var query = new ObjectQuery("SELECT * FROM Win32_VideoController");

using (var searcher = new ManagementObjectSearcher(scope, query))
{
    foreach (ManagementObject obj in searcher.Get())
    {
        foreach (PropertyData property in obj.Properties)
        {
            textBox1.AppendText($"{property.Name}: {obj[property.Name]}\r\n");
        }
    }
}

// 获取显卡信息
ManagementObjectSearcher searcher1 = new ManagementObjectSearcher("SELECT * FROM Win32_VideoController");
var countData = searcher1.Get(); // 可能会有多条记录

string vName = string.Empty;
string vRam = string.Empty;
string vDriverVersion = string.Empty;
string vDriverDate = string.Empty;
string vAdapterCompatibility = string.Empty;

foreach (ManagementObject queryObj in countData)
{
    vName = $"{queryObj["Name"]}";
    vRam = $"{queryObj["AdapterRAM"]}";
    vDriverVersion = $"{queryObj["DriverVersion"]}";
    vDriverDate = $"{queryObj["DriverDate"]}";
    vAdapterCompatibility = $"{queryObj["AdapterCompatibility"]}";
}

// 容量单位转换
int byteData = 0;
int.TryParse(vRam, out byteData);
int megaByte = byteData / (1024 * 1024);

// 驱动日期
string vDriverDateNew = string.Empty;
if (!string.IsNullOrEmpty(vDriverDate) && vDriverDate.Length >= 8)
{
    vDriverDateNew = $"{vDriverDate.Substring(0, 4)}年{vDriverDate.Substring(4, 2)}月{vDriverDate.Substring(6, 2)}日";
}

textBox1.AppendText($"显卡名称: {vName}\r\n");
textBox1.AppendText($"显存大小: {vRam}B，{megaByte}MB\r\n");
textBox1.AppendText($"显卡厂商: {vAdapterCompatibility}\r\n");
textBox1.AppendText($"驱动版本: {vDriverVersion}\r\n");
textBox1.AppendText($"驱动日期: {vDriverDateNew}\r\n");
