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-MM\dd\
/// </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 newWor
d = 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 + @"\result.doc";getsavefilename
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);
}
