求助:如何将Byte[]保存成Word文档

Question

求助:如何将Byte[]保存成Word文档Oracle 10g 中的Blob字段如果存储的是图片,可以方便地用Image对象转化成本地图片(如代码中注释的两行).
问题是如果BLOB字段中存储的是Word文档,如何取回在本地打开或保存.
谢谢  private void GetDBBlob(string strSelectCommandText)
        {
            DataSet ds = new DataSet();            ds = SelectOracle(strSelectCommandText, "T_ZTWJ");
            int rowCount = ds.Tables[0].Rows.Count;            if (rowCount > 0)
            {
                Byte[] byteBLOBData = new Byte[0];
                byteBLOBData = (Byte[])(ds.Tables[0].Rows[0]["WJNR"]);                System.IO.MemoryStream stmBLOBData = new System.IO.MemoryStream(byteBLOBData);
                //pictureBox1.Image = System.Drawing.Image.FromStream(stmBLOBData);
                //return System.Drawing.Image.FromStream(stmBLOBData);
            }
            else
            {
                //return null;
            }
        }

Answer 1

如果当时放入BLOB的就是该Word文档，用BinaryWriter写到后缀为.doc文件中就好了。

Answer 2

        private void GetDBBlob(string strSelectCommandText)
        {
            DataSet ds = new DataSet();            ds = SelectOracle(strSelectCommandText, "T_ZTWJ");
            int rowCount = ds.Tables[0].Rows.Count;            if (rowCount > 0)
            {
                Byte[] byteBLOBData = new Byte[0];
                byteBLOBData = (Byte[])(ds.Tables[0].Rows[0]["WJNR"]);                string fileName = "mydoc.doc";
                System.IO.FileStream fs=new System.IO.FileStream(fileName,System.IO.FileMode.Create,System.IO.FileAccess.Write);
                System.IO.BinaryWriter bw= new System.IO.BinaryWriter(fs);
                bw.Write(byteBLOBData);                bw.Flush();
                fs.Flush();
                bw.Close();
                fs.Close();
            }
            else
            {
                //return   null; 
            }
        }

Answer 3

Byte[] byteBLOBData = new Byte[0];
                byteBLOBData = (Byte[])(ds.Tables[0].Rows[0]["WJNR"]);
===============
这个写法有问题。应该直接写
Byte[] byteBLOBData = (Byte[])(ds.Tables[0].Rows[0]["WJNR"]);
