int pageWidth, pageHeight, totalPages, headerLength;
FileStream f = File.OpenRead(@"e:\test\1.docin");
//if(mFile.GetLength()<2) return;
//Stream f=
if (f.Length < 2) return;
//mFile.SeekToBegin();
//mFile.Read(&pageWidth,4);
//mFile.Read(&pageHeight,4);
//mFile.Read(&totalPages,4);
//mFile.Read(&headerLength,4);
byte[] temp = new byte[16];
f.Read(temp, 0, 16);
pageWidth = ConvertByte2Int(temp, 0, 4);
pageHeight = ConvertByte2Int(temp, 4, 4);
totalPages = ConvertByte2Int(temp, 8, 4);
headerLength = ConvertByte2Int(temp, 12, 4);

//BYTE *com=new BYTE[headerLength];
//mFile.Read(com,headerLength);
byte[] p = new byte[headerLength];
f.Read(p,4, headerLength);
报 偏移量和长度超出数组的界限，或者计数大于从索引到源集合结尾处的元素数量,怎么解决???

f.Read(p,4, headerLength);
如果headerLength=10的话那么你设置的参数4就是重第4个开始写入。。。而且写10个。。肯定要超出啊

[xu56180825]

要不你将headerLength+4要摸f.Read(p,0, headerLength);

byte[] buffer= System.IO.File.ReadAllBytes(@"");
int i = BitConverter.ToInt32(buffer, 0);
string s = Encoding.Default.GetString(buffer, 4, 60);
