C# 讀取Bin檔案並修改其內容

FileStream file_path = new FileStream(@BinFile, FileMode.OpenOrCreate, FileAccess.ReadWrite);

BinaryReader bin_read = new BinaryReader(file_path);

int dl = System.Convert.ToInt32(file_path.Length);

//讀取位元陣列

byte[] InData;

//讀取資料

InData = bin_read.ReadBytes(dl);

//釋放資源

bin_read.Close();

file_path.Close();

                 

FileStream temp_file_path = new FileStream(@TempBinFile, FileMode.OpenOrCreate, FileAccess.ReadWrite);

BinaryWriter bin_write = new BinaryWriter(temp_file_path);//創建BIN文件流

bin_write.Write(InData);

bin_write.Seek(8, SeekOrigin.Begin);//修改BIN文件位置從第8字節

bin_write.Write((byte)0x01);//第8字節改為01

bin_write.Write((byte)0x02);//第9字節改為02

bin_write.Write((byte)(0x90));//第10字節改為90

bin_write.Close();

temp_file_path.Close();
