PPC丢失后，手机信息如何保护？(C#)

核心提示： 首页完成改版，来提意见int dwsize = 0;SimInitialize(0, IntPtr.Zero, 0, ref hSim);SimReadRecord(hSim, EF_ICCID, SIM_RECORDTYPE_TRANSPARENT, 0, iccid, iccid.Length, ref dws

首页完成改版，来提意见

int dwsize = 0;

SimInitialize(0, IntPtr.Zero, 0, ref hSim);

SimReadRecord(hSim, EF_ICCID, SIM_RECORDTYPE_TRANSPARENT, 0, iccid, iccid.Length, ref dwsize);//在这里获取了SIM卡ID

SimDeinitialize(hSim);

return FormatAsSimString(iccid);

}

///

/// 对SIM卡ID进行格式化

///

///

byte格式的ID

/// 字符串格式

private static string FormatAsSimString(byte[] iccid)

{

string rawString = GetRawIccIDString(iccid);

return String.Format("{0} {1} {2} {3}", rawString.Substring(0, 6), rawString.Substring(6, 5), rawString.Substring(11, 4), rawString.Substring(15, 4));

}

///

/// 格式转换函数

private static string GetRawIccIDString(byte[] iccid)

{

System.Text.StringBuilder builder = new System.Text.StringBuilder();

int i = 0;

while (i < iccid.Length)

{

byte b = iccid[i];

builder.Append(ConvertInt4PairToString(b));

Math.Max(System.Threading.Interlocked.Increment(ref i), i - 1);

}

return builder.ToString();

}

private static string ConvertInt4PairToString(byte byteValue)

{

return ((byte)(byteValue << 4) | (byteValue >> 4)).ToString("x2");

}

}

}

核心代码我们有了，大家应该通过查资料和注释大概能理解程序要做的事情了吧，其实很简单，对不对?好，下一步我们在Programs.cs中添加功能调用代码如下：

Main

using System;

using Microsoft.WindowsMobile.PocketOutlook;

using System.Collections.Generic;

using System.Text;

using Microsoft.Win32;

using Microsoft.VisualBasic;

namespace SmartDeviceProject1

{
