程序 我百度搜到了。。 - -但是不会转成窗体 我刚学不到3天。。只是上大一学了点C语言基础 让我写这个太难为我了- -

using System;

namespace CRC {  public interface ICRC  {        long Value   {     get;   }      void Reset();      void Crc(int bval);      void Crc(byte[] buffer);      void Crc(byte[] buf, int off, int len);

 } }

你画个窗体,在窗体里调用这个方法就行了;那些控件编写编学就学会了。
