如何使用 C# 從 IOS 設備獲取 IMEI

Question

我需要使用 C# 讀取 IOS 設備的 IMEI ...

這在 C#/Xamarin 中是否可行？ 還是有另一個值可以用來識別設備？

Answer 1

一些設備標識符現在無法從 iOS 的公共 API 中獲取：

IMSI - 國際移動用戶識別碼（SIM 卡號）

IMEI - 國際移動設備識別碼（設備 ID）

UDID - Apple iDevices 的唯一設備標識符

MAC 地址 - 媒體訪問控制地址（網絡地址）

看看這里： http : //studyswift.blogspot.gr/2015/12/asidentifiermanager-get-idfv-vendor.html

如果您可以使用任何提供的 ID，代碼在 Swift 中，但如果您使用 C#/Xamarin，則轉換起來並不困難。

希望這有幫助

我也試圖找到一種方法來捕獲 IMEI，但我相信這是不可能的。 我解決它的唯一方法是使用此代碼，它返回序列號

 public class IosDevice 
 {
        [DllImport("/System/Library/Frameworks/IOKit.framework/IOKit")]
        private static extern uint IOServiceGetMatchingService(uint masterPort, IntPtr matching);

        [DllImport("/System/Library/Frameworks/IOKit.framework/IOKit")]
        private static extern IntPtr IOServiceMatching(string s);

        [DllImport("/System/Library/Frameworks/IOKit.framework/IOKit")]
        private static extern IntPtr IORegistryEntryCreateCFProperty(uint entry, IntPtr key, IntPtr allocator, uint options);

        [DllImport("/System/Library/Frameworks/IOKit.framework/IOKit")]
        private static extern int IOObjectRelease(uint o);

        public string GetIdentifier()
        {
            string serial = string.Empty;
            uint platformExpert = IOServiceGetMatchingService(0, IOServiceMatching("IOPlatformExpertDevice"));

            if (platformExpert != 0)
            {
                NSString key = (NSString)"IOPlatformSerialNumber";
                IntPtr serialNumber = IORegistryEntryCreateCFProperty(platformExpert, key.Handle, IntPtr.Zero, 0);

                if (serialNumber != IntPtr.Zero)
                {
                    serial = NSString.FromHandle(serialNumber);
                }

                IOObjectRelease(platformExpert);
            }

            return serial;
        }
    }

如果有人想在 MacOS 中獲得 USB 設備的 vid、pid

public class OsxDeviceDiscovery
{
    [DllImport("/System/Library/Frameworks/IOKit.framework/IOKit")]
    private static extern int IOServiceGetMatchingService(int masterPort, IntPtr matching);

            if (vendorID != 0x1234 || productID != 0x5678)
            {
