How to retrieve image from database
Aug 20 2012 9:28 AM
i have insert a image in database but when i retrieving the image from database then i m getting a error that parameter not find. i search the error then find that when the image is converted into bytes and stored into database then it takes 21432 bytes but when i retrieving that image from database then it shows only 13 bytes which are coming from database.
here i am posting my insert and retrieve code.
Code for insert image
------------------------------------
byte[] content = ImageToStream(openFileDialog1.FileName);
//string s = Encoding.ASCII.GetString(content).ToString();
byte[] imagebute = content.ToArray();
string s = (imagebute.Length).ToString();
con.Open();
SqlCommand com = new SqlCommand("insert into Table_1 values('" + content + "','" + s + "')", con);
com.ExecuteNonQuery();
pictureBox1.Image = null;
con.Close();--------------------------------------------------------
code for Retreive Image
-------------------------------------------
con.Open();
string sqlStatement="select image from Table_1 where id=" + textBox1.Text + " ";
SqlDataAdapter adapter=new SqlDataAdapter(sqlStatement,con);
DataTable dt=new DataTable("image");
adapter.Fill(dt);
MemoryStream ms=new MemoryStream((byte[])dt.Rows[0]["image"]);
Image image=Image.FromStream(ms,true);
byte[] content = (byte[])(dt.Rows[0]["image"]);
MemoryStream stream = new MemoryStream(content); // getting error here. parameter is not find
pictureBox2.Image = Image.FromStream(stream);
------------------------------------------------------------
is there any solution for this

Microsoft .NET libraries write directly to fields instead of using properties?
