How to save or get Images through Database.

Recently, I see lots of friends in CSDN　ask how to exchange non-text data with Database,
I looked up some materials and summary a sample . I will show you how to save or get images from SQL Server.
I hope it can give you some help.
Firstly, Create a database and a table in your SQL Server ,the table name is MyImages.
I create 3 fields in this table as follows:
1.Identity field that is named as “ID” type of int
2.Name field that is named as “Name”type of varchar
3.Image field that is named as “ImgField”type of Image
Secondly , create an C# Windows Application ,and add two buttons on the main form.
One’s name is “Save” the other’s “Get”.

Thirdly, add the following namespace which are necessary:
Using System.Data;
Using System.Data.SqlClient;
Using System.IO;
Fourthly, add Save and Get button’s Click event
Save_Click Event:
// Database Connection String
SqlConnection con = new SqlConnection("Server=YourServer;uid=yourName;pwd=yourpwd;database=yourdb");
SqlDataAdapter da = new SqlDataAdapter("Select * From MyImages", con);
SqlCommandBuilder MyCB = new SqlCommandBuilder(da);
DataSet ds = new DataSet("MyImages");
da.MissingSchemaAction = MissingSchemaAction.AddWithKey;
// Read Bitmap from file
FileStream fs = new FileStream(@"C:/winnt/Gone Your.BMP", FileMode.OpenOrCreate, FileAccess.Read);
// Put the data into byte array
byte[] MyData= new byte[fs.Length];
fs.Read(MyData, 0, System.Convert.ToInt32(fs.Length));

fs.Close();
da.Fill(ds,"MyImages");
DataRow myRow;
// Add a new Row to DataSet
myRow=ds.Tables["MyImages"].NewRow();
myRow["Description"] = "This would be description text";
// Set Img field value
myRow["imgField"] = MyData;
// Insert a record into database
ds.Tables["MyImages"].Rows.Add(myRow);
da.Update(ds, "MyImages");
con.Close();

Get_Click Event:
SqlConnection con = new SqlConnection("Server=YourServer;uid=yourName;pwd=yourpwd;database=yourdb");
SqlDataAdapter da = new SqlDataAdapter("Select * From MyImages", con);
SqlCommandBuilder MyCB = new SqlCommandBuilder(da);
DataSet ds = new DataSet("MyImages");
byte[] MyData= new byte[0];
da.Fill(ds, "MyImages");
DataRow myRow;
myRow=ds.Tables["MyImages"].Rows[0];
MyData = (byte[])myRow["imgField"];
int ArraySize = new int();
ArraySize = MyData.GetUpperBound(0);

FileStream fs = new FileStream(@"C:/winnt/Gone Fishing2.BMP", FileMode.OpenOrCreate, FileAccess.Write);
fs.Write(MyData, 0,ArraySize);
fs.Close();
