string seletc = "select * from search1 where contains(MyImage, '" +TextBox1.Text + "')";
SqlDataAdapter da = new SqlDataAdapter(seletc, myConn);
DataSet ds = new DataSet();
da.Fill(ds, "search");
DataGrid1.DataSource = ds.Tables["search"].DefaultView;
DataGrid1.DataBind();

TextBox1.Text = "";

string sql = "select * from search1 where id = '" + Request.QueryString["id"] + "'";
SqlConnection connection = new SqlConnection("server=(local);database=object;uid=sa;pwd=11331144;");
SqlCommand command = new SqlCommand(sql, connection);
connection.Open();
SqlDataReader dr = command.ExecuteReader();
if (dr.Read())
{
Response.Clear();
Response.Charset = "GB2312";
Response.ClearHeaders();
Response.BufferOutput = true;
Response.AddHeader("content-type", Request.QueryString["FileType"]);
Response.ContentType = "application/msword";
dr["MyImage"].ToString().Replace(TextBox1.Text, "<font color=red>" + TextBox1.Text + "</font>");
Response.BinaryWrite((byte[])dr["MyImage"]);
}
dr.Close();
connection.Close();
}
}
我用replace替换了关键字但打开文件还是什么效果都没，哪位大侠看看是怎么回事谢谢，在线等 --------------------编程问答-------------------- 哪位大侠帮忙看看 100分求各位大侠解决一下问题谢谢 --------------------编程问答--------------------
--------------------编程问答-------------------- 不好意思,忘不了tostring 了
// dr["MyImage"].ToString().Replace(TextBox1.Text, " <font color=red> " + TextBox1.Text + " </font> ");
//上面这行不要
//Response.BinaryWrite((byte[])dr["MyImage"]);
//上面这行换为
Response.BinaryWrite((byte[])dr["MyImage"].Replace(TextBox1.Text, " <font color=red> " + TextBox1.Text + " </font> ");
--------------------编程问答-------------------- 大哥还是提示错误呀
Response.BinaryWrite((byte[])dr["MyImage"].ToString().Replace(TextBox1.Text, " <font color=red> " + TextBox1.Text + " </font> ");
提示无法将byte[]类型转换为string类型能教我怎么解决吗 --------------------编程问答-------------------- 那么哪一列是要被高亮的,列名叫什么,你将对应的处理一下就行了. --------------------编程问答-------------------- MyImage列是要被高亮的myImage列是我数据库文件存储的列,我需要怎么处理呀? --------------------编程问答-------------------- jf
