Storing images in SQL database using Asp.net

How can I Store images in SQL database using Asp.net ?

The following code shows how to use ADO.NET to store image field in SQL Server.

Code:

---

public void StorePicture( string filename )
{
  // Read the file into a byte array
  using(FileStream fs = new FileStream(filename, FileMode.Open, FileAccess.Read))
  {
    byte[] imageData = new Byte[fs.Length];
    fs.Read( imageData, 0, (int)fs.Length );
  }

  using( SqlConnection conn = new SqlConnection(connectionString) )
  {
    SqlCommand cmd = new SqlCommand("StorePicture", conn);
    cmd.CommandType = CommandType.StoredProcedure;
    cmd.Parameters.Add("@filename", filename );
    cmd.Parameters["@filename"].Direction = ParameterDirection.Input;
    cmd.Parameters.Add("@blobdata", SqlDbType.Image);
    cmd.Parameters["@blobdata"].Direction = ParameterDirection.Input;
    // Store the byte array within the image field
    cmd.Parameters["@blobdata"].Value = imageData;
    conn.Open();
    cmd.ExecuteNonQuery();
  }
}

You can use this stored procedure to add image to sql database manually.

Code:

---

CREATE      PROCEDURE [sp_AddImage]
        (   
                @img_pk        INT        OUTPUT    ,
                @img_data        IMAGE               
        )
AS
    INSERT INTO tbl_Image ( img_data)
    VALUES ( @img_data )

    IF @@ROWCOUNT=1
    SET @img_pk=@@IDENTITY
GO
