I am trying to convert BLOB data that's coming from MySQL database to Base64 and then displaying this to an jpg image.. here's the code am using:
using (MySql.Data.MySqlClient.MySqlConnection connection = new MySql.Data.MySqlClient.MySqlConnection("S;Port=P;Database=DB;Uid=U;Pwd=P"))
{
connection.Open();
MySql.Data.MySqlClient.MySqlCommand cmd = connection.CreateCommand();
cmd.CommandText = "SELECT blobValue FROM Table WHERE blob_id = '333'";
MySql.Data.MySqlClient.MySqlDataReader datr = cmd.ExecuteReader();
if (datr.Read())
{
byte[] xx = (byte[])datr.GetValue(0);
string base64String = Convert.ToBase64String(xx, 0, xx.Length);
Image1.ImageUrl = "data:image/jpg;base64," + base64String;
}
I guess am not having a problem with the code, but when running the code i get an empty picture, like this one -->
Please some help.
Use following code.
public string BlobToStringConverter(OracleDbType.Blob blobObject){
if (blobObject != null){
return Encoding.UTF8.GetString((byte[])(blobObject));
} else {
return string.Empty;
}
}
