I failed to convert following 2 type of data into readable record by using following code. This data migrated from lotus note to sql server by using LEI.
Anyone know how?

in image data type:

in binary data type:

string sqlText = "..."
 SqlConnection connection = new SqlConnection(ConfigurationManager.ConnectionStrings["connectionString"].ToString());
        SqlCommand command = new SqlCommand(sqlText, connection);

        //open the database and get a datareader
        SqlDataReader dr = command.ExecuteReader();
        if ( dr.Read()) //yup we found our image
const int CHUNK_SIZE = 2 * 1024;
       byte[] buffer = new byte[CHUNK_SIZE];
       long bytesRead;
       long fieldOffset = 0;
       using (var stream = new MemoryStream())
           while ((bytesRead = dr.GetBytes(dr.GetOrdinal("checklist"), fieldOffset, buffer, 0, buffer.Length)) > 0)
           // while ((bytesRead = dr.GetBytes(dr.GetOrdinal("CCList"), fieldOffset, buffer, 0, buffer.Length)) > 0)
               stream.Write(buffer, 0, (int)bytesRead);
               fieldOffset += bytesRead;

Solution 1

what exactly do you want to do?
I think you want to save a image to a database and then retrieve it?

import: load your image, then convert it to a byte-array and then you can add it into your db..
orm you can convert the byte array into a base64-string?
