private string Distinguish64or32System()
{
try
{
string addressWidth = String.Empty;
ConnectionOptions mConnOption = new ConnectionOptions();
ManagementScope mMs = new ManagementScope("//localhost", mConnOption);
ObjectQuery mQuery = new ObjectQuery("select AddressWidth from Win32_Processor");
ManagementObjectSearcher mSearcher = new ManagementObjectSearcher(mMs, mQuery);
ManagementObjectCollection mObjectCollection = mSearcher.Get();
foreach (ManagementObject mObject in mObjectCollection)
{
addressWidth = mObject["AddressWidth"].ToString();
}
return addressWidth;
}
catch
{
return "版本类型不支持";
}
}
