查询了API中FindFirstUrlCacheEntryEx方法的定义，后修改FindFirstUrlCacheEntryEx定义如下：

        [DllImport("wininet.dll")]

        //Starts a filtered enumeration of the Internet cache.

        public static extern IntPtr FindFirstUrlCacheEntryEx(

          //A pointer to a string that contains the source name pattern to search for. 

          //This parameter can only be set to "cookie:", "visited:", or NULL. 

          //Set this parameter to "cookie:" to enumerate the cookies 

          //or "visited:" to enumerate the URL History entries in the cache. 

          //If this parameter is NULL, FindFirstUrlCacheEntryEx returns all content entries in the cache.

          string lpszUrlSearchPattern,

          //Controls the enumeration. No flags are currently implemented; this parameter must be set to zero.

          uint dwFlags,

          //A bitmask indicating the type of cache entry and its properties. 

          //The cache entry types include: 

          //history entries (URLHISTORY_CACHE_ENTRY), 

          //cookie entries (COOKIE_CACHE_ENTRY), 

          //and normal cached content (NORMAL_CACHE_ENTRY).

          uint dwFilter,

          //ID of the cache group to be enumerated. Set this parameter to zero to enumerate all entries that are not grouped.

          Int64 GroupId,

          //Pointer to a INTERNET_CACHE_ENTRY_INFO  structure to receive the cache entry information.

          IntPtr lpFirstCacheEntryInfo,

          //Pointer to variable that indicates the size of the structure referenced by the lpFirstCacheEntryInfo parameter, in bytes.

          ref uint lpdwFirstCacheEntryInfoBufferSize,

          //This parameter is reserved and must be NULL.

          IntPtr lpGroupAttributes,

          //This parameter is reserved and must be NULL.

          IntPtr pcbGroupAttributes,

          //his parameter is reserved and must be NULL.

          IntPtr lpReserved

        );

然后这么调用就可以了：


 FindNextUrlCacheEntryEx(vHandle, (IntPtr)null, ref vFirstCacheEntryInfoBufferSize, IntPtr.Zero, IntPtr.Zero, IntPtr.Zero);

FindNextUrlCacheEntryEx(vHandle, vBuffer, ref vFirstCacheEntryInfoBufferSize, IntPtr.Zero, IntPtr.Zero, IntPtr.Zero)

要取到标题
API里面能取到标题吗

通过下面的方式使用wininet.dll里面的API可以实现，下面是一个函数的声明。
[DllImport("wininet.dll", CallingConvention=CallingConvention.StdCall, CharSet=CharSet.Auto, SetLastError=true)]
public static extern bool FindNextUrlCacheGroup(IntPtr hFind, ref long lpGroupId, IntPtr lpReserved);

wininet.dll的方法你可以参考MSDN里面：ms-help://MS.MSDNQTR.v90.en/wininet/wininet/wininet_functions.htm

或者在索引里面输入FindNextUrlCacheGroup找到这个函数然后关联过去即可。

别人已经实现的你也可以参考一下，有源代码的：http://www.freevbcode.com/ShowCode.asp?ID=6702
