VB.NET读内存储器用用哪个类？刚学~·不明白

VB.NET读内存用用哪个类？？？刚学~~·不明白！
在VB6.0中，读内存常常用到这样的API，分5个步骤就搞定了
（1-找窗口标题，2-得到ThreadProcessId，3-打开进程，4-读取内存，5-CloseHandle）

Public   Declare   Function   FindWindow   Lib   "user32 "   Alias   "FindWindowA "   (ByVal   lpClassName   As   String,   ByVal   lpWindowName   As   String)   As   Long
Public   Declare   Function   GetWindowThreadProcessId   Lib   "user32 "   (ByVal   hwnd   As   Long,   lpdwProcessId   As   Long)   As   Long
Public   Declare   Function   OpenProcess   Lib   "kernel32 "   (ByVal   dwDesiredAccess   As   Long,   ByVal   bInheritHandle   As   Long,   ByVal   dwProcessId   As   Long)   As   Long
Public   Declare   Function   ReadProcessMemory   Lib   "kernel32 "   (ByVal   hProcess   As   Long,   lpBaseAddress   As   Any,   lpBuffer   As   Any,   ByVal   nSize   As   Long,   lpNumberOfBytesWritten   As   Long)   As   Long
Public   Declare   Function   CloseHandle   Lib   "kernel32 "   (ByVal   hObject   As   Long)   As   Long

到了VB2005,我不知道该怎么办了~~~~？？？？？

用内存流啊。
