在现有的.net compact framework中，无论是1.0、2.0还是3.5版本，都没有直接获取用户通话记录的接口，那么，我们只能自己封装底层API来实现了。
改接口在phone.dll中，调用PhoneGetCallLogEntry方法会返回一个通话记录结构，在该结构中，包含号码、姓名、通话开始时间、通话结束时间等信息。在我们调用此API之前，首先要PhoneOpenCallLog打开通话记录句柄，同时在操作结束后，要调用 PhoneCloseCallLog关闭句柄，废话少说，看代码。

public struct CALLLOGENTRY
{

public bool fOutgoing;
public bool fConnected;
public bool fEnded;
public bool fRoam;
public short cidt;
public IntPtr pszNumber;

在windows mobile5.0和windows mobile6.0上测试通过。
