創(chuàng)建DAT文件 及讀取數(shù)據(jù) DAT文件 *.DAT 從后綴名上也能理解其中的含義即：data文件，數(shù)據(jù)文件；
首先引入：using System.IO;
創(chuàng)建bat文件:

public static string FILE_PATH_ENTRUST = @"../\../\File/\FileRecord/\EntrustRecord.dat";

寫入數(shù)據(jù)：

private void WriteDicFile(){BinaryWriter bw = null;try{//將模塊數(shù)據(jù)寫入二進(jìn)制文件bw = new BinaryWriter(new FileStream(FILE_PATH_ENTRUST, FileMode.Create));FileDic.WriteBinary(bw, m_dic);bw.Close();}catch (IOException ex){if (null != bw){bw.Close();}MessageBox.Show(ex.Message + "\n Cannot write to file.");return;}} public static void WriteBinary(BinaryWriter bw, Dictionary<string, FileDic> dic){//寫入字典的長(zhǎng)度bw.Write(dic.Count);//遍歷寫入字典內(nèi)容foreach (KeyValuePair<string, FileDic> kv in dic){bw.Write(kv.Key);kv.Value.WriteBinary(bw);}}

讀取數(shù)據(jù)：

private bool ReadDicFile(){if (!File.Exists(FILE_PATH_ENTRUST)){return false;}BinaryReader br = null;try{br = new BinaryReader(new FileStream(FILE_PATH_ENTRUST, FileMode.Open));FileDic.ReadBinary(br, m_dic);br.Close();}catch (IOException ex){if (null != br){br.Close();}MessageBox.Show(ex.Message + "\n Cannot read to file.");return false;}return true;} public static void ReadBinary(BinaryReader br, Dictionary<string, FileDic> dic){//讀取字典長(zhǎng)度int size = br.ReadInt32();//依次讀取字典內(nèi)容for (int i = 0; i < size; i++){string filename = br.ReadString();FileDic fd = new FileDic();fd.ReadBinary(br);dic.Add(filename, fd);}}
