C# BinaryFormatter二进制格式序列化和反序列化对象

1. 从文件中获取二进制信息并反序列化，返回指定的type的对象

 /// 

 /// 二进制反序列化，并返回指定的type的对象
 /// 
 /// 要返回类型的对象
 /// 二进制文件完整路径
 /// 
 private static object FromFile(Type type, string strPath)
    {
      if (type == (Type) null)
        return (object) null;
      object obj = (object) null;
      if (!string.IsNullOrEmpty(strPath) && File.Exists(strPath))
      {
        System.IO.FileStream fileStream = new System.IO.FileStream(strPath, FileMode.Open, FileAccess.Read, FileShare.Read);
        try
        {
          obj = new BinaryFormatter().Deserialize((Stream) fileStream);
          fileStream.Close();
        }
        catch (Exception ex)
        {
          FormReportException.Report(ex);
          fileStream.Close();
          return obj;
        }
      }
      return obj;
    }

2. 将对象序列化为二进制，并存储到文件中

/// 

/// 将对象序列化为二进制
/// 
/// 需要序列化的对象
/// 二进制存储文件路径
private static void ToFile(object obj, string strPath)
    {
      if (obj == null || string.IsNullOrEmpty(strPath))
        return;
      System.IO.FileStream fileStream = !File.Exists(strPath) ? new System.IO.FileStream(strPath, FileMode.OpenOrCreate) : new System.IO.FileStream(strPath, FileMode.Truncate);
      try
      {
        new BinaryFormatter().Serialize((Stream) fileStream, obj);
        fileStream.Close();
      }
      catch (Exception ex)
      {
        FormReportException.Report(ex);
        fileStream.Close();
      }
    }

3. 使用

private DataTable m_dt;
 public AntGISEditorSetting(IEngineEditor pEngineEditor)
    {
      string m_strFilePath = System.IO.Path.Combine(AntGIS.Desktop.Config.Path.Config, "Editor\\Option.dat");
      if (!File.Exists(m_strFilePath))
      {
        this.m_dt = new DataTable();
        this.m_dt.TableName = "EditorSetting";
        this.m_dt.Columns.Add("SettingName", typeof (string));
        this.m_dt.Columns.Add("SettingValue", typeof (object));
        this.m_dt.Columns.Add("SettingType", typeof (string));
        DataRow row1 = this.m_dt.NewRow();
        row1[0] = (object) "OptionByArcGIS";
        row1[1] = (object) false;
        row1[2] = (object) "bool";
        this.m_dt.Rows.Add(row1);
        DataRow row2 = this.m_dt.NewRow();
        row2[0] = (object) "AutoChamfer";
        row2[1] = (object) false;
        row2[2] = (object) "bool";
        this.m_dt.Rows.Add(row2);
        DataRow row3 = this.m_dt.NewRow();
        row3[0] = (object) "AutoReShape";
        row3[1] = (object) false;
        row3[2] = (object) "bool";
        this.m_dt.Rows.Add(row3);
      //序列化二进制
       ToFile(this.m_dt, this.m_strFilePath);
      }
      else
        //反序列化二进制
        this.m_dt = FromFile(typeof (DataTable), this.m_strFilePath) as DataTable;
    }
