C#判断二进制文件读取到末尾！

1、objFileStream = New FileStream( MapPath( "files.cfg" ), FileMode.Open )objBinaryReader = New BinaryReader( objFileStream)file_id = objBinaryReader.ReadInt32()file_version = objBinaryReader.ReadInt32(）这是读二进制文件的代码，请问，如何判断读到文件尾了？

2、第一：try{file_id = objBinaryReader.ReadInt32()file_version = objBinaryReader.ReadInt32()}catch(EndOfStreamException e){到了结尾}

3、第二：先取出文件的长度。然后记得你每次读取的字节数FileStream fs = new 掂迎豢畦FileStream("data.bin&鳎溻趄酃quot;, FileMode.OpenOrCreate);BinaryReader r = new BinaryReader(fs);r.BaseStream.Seek(0,SeekOrigin.Begin); //将文件指针设置到文件开始while (r.BaseStream.Position < r.BaseStream.Length) // 当未到达文件结尾时｛｝

4、第三：r.BaseStream.Seek(0,SeekOrigin.Begin);while (r.Peek() > -1)｛｝
