错在哪里了为什么读取出来打开word里面只显示：System.Byte[]这几个字
//word文件上传按钮
private void button2_Click(object sender, EventArgs e)
{
OleDbConnection Conn;
Conn = new OleDbConnection(StartWindow.StrConn);
Conn.Open();
string location = textBox1.Text;
string[] argLocation= location.Split(new Char[] {'\\'});
int i = argLocation.Length;
linkLabel1.Text = argLocation[i-1];
System.IO.FileStream fs = new System.IO.FileStream(@location,System.IO.FileMode.Open);
fs.Position = 0;
byte[] content = new byte[fs.Length];
fs.Read(content, 0, (int)fs.Length);
fs.Close();
// OleDbDataAdapter da;
string strUpdate = "update Base_TAnswerFile set DeviationTable='" + content + "',ItemInformation='招标项目信息'";
OleDbCommand cmd = new OleDbCommand(strUpdate,Conn);
cmd.CommandText = strUpdate;
cmd.ExecuteNonQuery();
cmd.Dispose();
Conn.Close();
Conn.Dispose();
Conn.Close();
}
private void linkLabel1_LinkClicked(object sender, LinkLabelLinkClickedEventArgs e)
{
//读取二进制文件转化为word文档
string filePath = "E:\\test.doc";
string fileName = filePath;
if (System.IO.File.Exists(fileName))
{
System.IO.File.Delete(fileName);
}
//OleDbDataAdapter da;
OleDbConnection Conn;
Conn = new OleDbConnection(StartWindow.StrConn);
Conn.Open();
//da = new OleDbDataAdapter(@"select DeviationTable from Base_TAnswerFile ", Conn);
OleDbCommand com = Conn.CreateCommand();
//DataSet testDataSet = new DataSet();
//da.Fill(testDataSet, "Base_TAnswerFile");
com.CommandText = "select DeviationTable from Base_TAnswerFile";
byte[] content = (byte[])com.ExecuteScalar();//读取之后转换成二进制字节数组
System.IO.FileStream fs = new System.IO.FileStream(fileName, System.IO.FileMode.Create);
fs.Write(content, 0, content.Length);
fs.Flush();
fs.Close();
Conn.Close();
}
