将RichTextBox的内容直接写入数据库：
private void button1_Click(object sender, EventArgs e) { System.IO.MemoryStream mstream = new System.IO.MemoryStream(); this.richTextBox1.SaveFile(mstream, RichTextBoxStreamType.RichText); //将流转换成数组 byte[] bWrite = mstream.ToArray(); //将数组写入数据库 System.Data.SqlClient.SqlParameter[] pram ={ sqlHelper.MakeInParam("@XX",System.Data.SqlDbType.Image) }; pram[0].Value = bWrite; sqlHelper.RunSql("insert into XXX (XX) values (@XX)", pram); } 将数据库中的RTF读出并填充到RichTextBox private void button2_Click(object sender, EventArgs e) { //从数据库中读出数据 DataTable dt=sqlHelper.GetDataTable("select XX from XXX where ....."); byte[] bWrite = (byte[])dt.Rows[0][0]; //将数组转换成stream System.IO.MemoryStream mstream = new System.IO.MemoryStream(bWrite, false); //将stream填充到RichTextBox this.richTextBox1.LoadFile(mstream, RichTextBoxStreamType.RichText); } |
