Doesnt search the right data from Database

Question

Hi,

 

I have data into my DB (five records). When I search for example the number "3" its sturk and give the error message: the parameter it's not valide. Curiosly all number out of numbers inside of my DB (1,2,3,4,5) its says "Data not find".

private void button2_Click(object sender, EventArgs e)
{
conn.Open();
string sqlQuery = "select * from test where id ='" + textID.Text + "'";
cmd = new SqlCommand(sqlQuery, conn);
SqlDataReader DataRead = cmd.ExecuteReader();
DataRead.Read();
if (DataRead.HasRows)
{
textName.Text = DataRead[1].ToString();
byte[] img = ((byte[])DataRead[2]);
if (img == null)
{
pictureBox1.Image = null;
}
else
{
MemoryStream mstream = new MemoryStream(img);
pictureBox1.Image = Image.FromStream(mstream); // Its sturk here on this line
}
}
else
{
MessageBox.Show("Data not find");
}
conn.Close();
}
