Here is my class (product.cs) where is the method to insert the image:
public static void InsertProductIMG(byte[] image, string contentType) //Insere Produto.
{
string cs = "Data Source=(local);Initial Catalog=SiteTD;Integrated Security=True";
string comandoSql = "INSERT INTO [SiteTD].[dbo].[produto] (image, ContentType) VALUES (@image, @contentType)";
using (SqlConnection conn = new SqlConnection(cs))
{
conn.Open();
using (SqlTransaction trans = conn.BeginTransaction())
{
try
{
SqlCommand cmd = new SqlCommand(comandoSql, conn, trans);
SqlParameter[] parms = new SqlParameter[2];
parms[0] = new SqlParameter("@imagem", imagem);
parms[1] = new SqlParameter("@contentType", contentType);
foreach (SqlParameter p in parms)
{
cmd.Parameters.Add(p);
}
cmd.ExecuteNonQuery();
trans.Commit();
}
catch (Exception ex)
{
trans.Rollback();
throw (ex);
}
}
}
}
Here is the code behind of the apsx page where I call the method above:
byte[] imageBytes = new byte[fupld.PostedFile.InputStream.Length];
product.InsertProductIMG(imageBytes, "image/jpeg");//product is the class where the method is
Now I'd like to know how can I display this image?
Would I have to read the byte[] from sql
(SELECT), convert to string and so convert to byte[]? And after do that
convert to bitmap (System.Drawing). But how I show this bitmap in a aspx page?
I've no idea how to do it. Please help!! :]
Thanks
Obs.: In sql, the column image is a varbinary(MAX).
I don't know VB, only C# :[
