• c# word文档与二进制数据的相互转换


    最近项目出使用到了将word文档以二进制的方法存到数据库中,并再次读取出二进制数据转换为word文档。最后总结了一下,不多说看示例方法:
     

    代码
            /// <summary>
            
    /// 二进制数据转换为word文件
            
    /// </summary>
            
    /// <param name="data">二进制数据</param>
            
    /// <param name="fileName">word文件名</param>
            
    /// <returns>word保存的相对路径</returns>
            public string ByteConvertWord(byte[] data, string fileName)
            {
                
    string savePath = @"SystemWord"+FormatNowTime(2)+@"";

                
    if (!System.IO.Directory.Exists(GetPath() + savePath))
                {
                    Directory.CreateDirectory(GetPath() 
    + savePath);
                }
                savePath 
    += fileName + ".doc";
                
    string filePath = GetPath() + savePath;

                FileStream fs;
                
    if (System.IO.File.Exists(filePath))
                {
                    fs 
    = new FileStream(filePath, FileMode.Truncate);
                }
                
    else
                {
                    fs 
    = new FileStream(filePath, FileMode.CreateNew);
                }
                BinaryWriter br 
    = new BinaryWriter(fs);
                br.Write(data, 
    0, data.Length);
                br.Close();
                fs.Close();
                
    return savePath;
            }

            
    /// <summary>
            
    /// word文件转换二进制数据(用于保存数据库)
            
    /// </summary>
            
    /// <param name="wordPath">word文件路径</param>
            
    /// <returns>二进制</returns>
            private byte[] wordConvertByte(string wordPath)
            {
                
    byte[] bytContent = null;
                System.IO.FileStream fs 
    = null;
                System.IO.BinaryReader br 
    = null;
                
    try
                {
                    fs 
    = new FileStream(wordPath, System.IO.FileMode.Open);
                }
                
    catch
                {
                }
                br 
    = new BinaryReader((Stream)fs);
                bytContent 
    = br.ReadBytes((Int32)fs.Length);

                
    return bytContent;
            }

            
    /// <summary>
            
    /// 项目所在目录
            
    /// </summary>
            
    /// <returns></returns>
            public string GetPath()
            {
                
    return Application.StartupPath;
            }

            
    /// <summary>
            
    /// 格式化当前时间: 
            
    /// 1:yyMMddHHmmss; 2:yyyy-MMdd
            
    /// </summary>
            
    /// <returns></returns>
            public string FormatNowTime(int num)
            {
                
    if (num == 1)
                {
                    
    return DateTime.Now.ToString("yyMMddHHmmss");
                }
                
    else if (num == 2)
                {
                    
    return DateTime.Now.ToString("yyyy-MM"+ @"" + DateTime.Now.Day;
                }
                
    return "";
            }

    //测试方法
     private void button1_Click(object sender, EventArgs e)
            {
                
    string newWord = ByteConvertWord(wordConvertByte(@"D:测试文件.doc"), "测试成功");
            }

    //将文件转换为二进制,并保存到数据库中
               
    string strResult = strPath + @" esult.doc";
                System.IO.FileStream fs
    = new System.IO.FileStream(@strResult, System.IO.FileMode.Open);
                fs.Position
    = 0;
               
    byte[] content = new byte[fs.Length];
                fs.Read(content,
    0, (int)fs.Length);
                fs.Close();
                fluidDesignDoc.qhse1
    = content;//其中qhse1在数据库中保存的类型为OLE对象
                IFluidDesignDocManager manager = new FluidDesignDocManager(); manager.UpdateFluidDesignDoc(fluidDesignDoc); ----

    //将二进制数据转化为指定位置文件
    private void getFile(byte[] content, string filePath)
            {
               
    string fileName = filePath;
               
    if (System.IO.File.Exists(fileName))
                {
                    System.IO.File.Delete(fileName);
                }
               
    //FileStream sw = new FileStream(@fileName, FileMode.Create);
               
    //StreamWriter fs = new StreamWriter(sw, Encoding.UTF8);
               
    //fs.Write(entity.Content);
                System.IO.FileStream fs = new System.IO.FileStream(fileName, System.IO.FileMode.Create);
                fs.Write(content,
    0, content.Length);
                fs.Flush();
                fs.Close();
                fileName
    = System.IO.Path.Combine(Application.StartupPath, fileName);
            }
