c# 将textbox的值保存为doc格式到D盘

private void SaveToDoc()
        {
            byte[] fileBytes = System.Text.Encoding.Default.GetBytes(textBox1.Text.ToString().Trim());
            SaveFileDialog sfd = new SaveFileDialog();
            sfd.Filter = "word文件|*.doc";
            if (sfd.ShowDialog() == DialogResult.OK)
            {
                try
                {
                    string saveFileName = sfd.FileName;
                    FileStream fs = new FileStream(saveFileName, FileMode.OpenOrCreate, FileAccess.Write);
                    BinaryWriter br = new BinaryWriter(fs);
                    br.Write(fileBytes, 0, fileBytes.Length);
                    br.Close();
                    fs.Close();
                    if (MessageBox.Show("文件保存成功，是否立即打开文件？") == System.Windows.Forms.DialogResult.OK)
                    {
                        Process.Start(saveFileName);
                    }
                }
                catch (Exception ex)
                {
                    MessageBox.Show(ex.Message);
                }
            }
        }

你要是路径已经确定了的话，就不用SaveFileDialog了，直接给saveFileName赋值就可以了。
