Storing Images in MySQL database

We may need to store the images in the database. It is easy and pretty simple.

The basic idea is;
1) The images are stored in database as bytes. In MySQL database we need to create a field/column of type "Blob".
2) Need to use FileStream and BinaryReader objects to convert images into bytes.

Here is the C# code, to do the task

Table schema:

C# code:
MySqlConnection mcon = null;
MySqlCommand cmd = null;
FileStream fsObj = null;
BinaryReader binRdr = null;
try
{
//converting image to bytes
fsObj = File.OpenRead(pictureBox1.ImageLocation);
byte[] imgContent = new byte[fsObj.Length];
binRdr = new BinaryReader(fsObj);
imgContent = binRdr.ReadBytes((int)fsObj.Length);
mcon = new MySqlConnection("server=localhost;user=root;pwd=root;database=test;");
mcon.Open();
//inserting into MySQL db
cmd = new MySqlCommand("insert into users (userid,username,userphoto) values (@userid, @username, @userphoto)", mcon);
cmd.Parameters.Add(new MySqlParameter("@userid", (object)textBox1.Text));
cmd.Parameters.Add(new MySqlParameter("@username", (object)textBox2.Text));
cmd.Parameters.Add(new MySqlParameter("@userphoto", (object)imgContent));
MessageBox.Show(cmd.ExecuteNonQuery().ToString() + " rows affected");
}
catch (MySqlException mex)
{
MessageBox.Show(mex.Message);
}
finally
{
if (binRdr != null)binRdr.Close();
binRdr = null;

if (fsObj != null)fsObj.Close();
fsObj = null;
if (cmd != null)cmd.Dispose();
cmd = null;

if (mcon != null)
{
if (mcon.State == ConnectionState.Open)
mcon.Close();
}
}

The above code will export the selected image into MySQL database. Please note that based on the image size we may need to define the blob datatype as "tinyblob", "blob", "mediumblob"or "longblob".

XML Documentation comments

Image
When we are doing the coding, we need to use our own functions/methods to do a certain task. But while writing the function we may missed out the function details like why the function has been written . So whenever writing a function, if we use the documentation comments standard, it will help in the future whoever uses the function. Here is syntax; /// /// documentation block /// Here is the simple function defined in C# IDE; documentation comments added here; Intellisense is displaying the documentation comments.

DataTable ExtendedProperties

While playing in data tables in .net, it may require to have some temporary values such as records counts, primary key field name, …etc. In those situations, instead of declaring new variables in the program, it is ideal way to use “ExtendedProperties” option in datatable. The property is holding the collection (hashtable) values. Here is the syntax; DataTable.ExtendedProperties.Add (object key, object value); Examples; DataTable dtObj = new DataTable("employees"); dtObj.ExtendedProperties.Add("totalCount", 500); dtObj.ExtendedProperties.Add("primaryKey", "employee_id"); dtObj.ExtendedProperties.Add("createdDate", DateTime.Now); For retrieving assigned properties, int iCount = Convert.ToInt32(dtObj.ExtendedProperties["totalCount"].ToString()); So simple and effective property.
