A delegate is a variable that holds a function.

namespace delegateexample1
{
    delegate string[] mydelegate(string str);

    class Program
    {

        static void Main(string[] args)
        {
            mydelegate mymy = new mydelegate(testdeligate.replacestring);
            mydelegate mimi = new mydelegate(testdeligate.splitstringup);

            string[] str= mymy("Ade is a good boy");
            string[] str1 = mimi("Ayo is a nice boy");
            foreach (string x in str)
            {
                Console.WriteLine("\t\n{0}", x);
            }
            Console.WriteLine("\t ");
            foreach (string x in str1)
            {
                Console.WriteLine("\t\n{0}", x);
            }
            Console.ReadLine();

        }
        class testdeligate
        {

            public static string[] replacestring(string s)
            {
                string[] marray = s.Split(' ');
                //StringSplitOptions option=new StringSplitOptions();
                //Console.WriteLine("Replace Space with Hyphen...");
                //return s.Split(marray, option);
                //return s.Replace(' ','-');
                return marray;
            }
            public static string[] splitstringup(string s)
            {
                 string[] hiarray = s.Split(' ');
                 return hiarray;

Silverlight:

silverlight allows deffernt browsers thru .net code on variety of operating system.
silverlight works thru a browser plug-in and provides a subset of the .net framework class library..

silverlight is for client, allows to create richer pages than you could with HTML,DHTML, and JavaScript alone.

silvertlight duplicates the features of adobeflash and echoes the goals of Adobe flash.
BY using silverlight you can draw sophisticated 2D graphics, animate scence and play video and other media files.

Silverlight is perfect for creating a mini-applet, like a browser-hosted game.

It’s also a good choice for adding interactive media and animation to a website

but you can freely mix ASP.NET pages and Silverlight pages on a website—or place Silverlight content in an ASP.NET page.

For example,
although you can use Silverlight to create an animated button, this is a risky strategy. Users without the
Silverlight plug-in won’t be able to see your button or interact with it. (Of course, you could create more
than one front end for your web application, using Silverlight if it’s available or falling back on regular
ASP.NET controls if it’s not. However, this approach requires a significant amount of work.)

c# tutorial

Coding4Fun book, Coding4Fun 10 .NET Programming Projects for Wiimote, World of Warcraft, YouTube, and More officially released to the world last week. Unlike your typical .NET development book, Coding4Fun is about learning how to use your developer skills to do fun, cool projects (see below for the full list). All of the .NET projects are in VB and C#, with the exception of the XNA chapter as XNA only supports C# at this time.

c# tutorial

USING LINQ TO SQL INSERT INTO DATABASE

Saving to the database using LINQToSQL

Step1:
Create the database in MSSQL Management studio

Step2:
Connect to the MSSQL Database from Visual Studio

Step3:
Design the interface to take name,Mat no and picture

Step4:
Add LINQ to Sql classes from Visual Studio

Step5:
Write The codes like this

CODES TO INSERT INTO THE DATABASE:

customerDataContext db;
        CustomerTB cust;
        private void btnsubmit_Click(object sender, EventArgs e)
        {
            db = new customerDataContext();
            cust = new CustomerTB()
            {
                ID = txtboxmatno.Text,
                name = txtboxname.Text,
                photo=pix
            };

            db.CustomerTBs.InsertOnSubmit(cust);
            db.SubmitChanges();
            txtboxmatno.Clear();
            txtboxname.Clear();
        }

CODES TO BROWSE FOR THE PICTURE:

OpenFileDialog openfile;
        string path;
        byte[] pix;
        FileStream fs;
        private void btnbrowse_Click(object sender, EventArgs e)
        {
            openfile = new OpenFileDialog();
            openfile.ShowDialog();
            path = openfile.FileName;
            pictureBoxsubmit.Image = Image.FromFile(path);
            pictureBoxsubmit.SizeMode = PictureBoxSizeMode.StretchImage;
            fs = new FileStream(path, FileMode.Open, FileAccess.Read);
            pix=new byte[fs.Length];
            fs.Read(pix, 0, Convert.ToInt32(fs.Length));

        }

CODES TO RETRIVE NAME AND PICTURE:

ImageConverter imageconvert;
        private void btnretrieve_Click(object sender, EventArgs e)
        {
            byte[] retrevedPix = null;
            imageconvert = new ImageConverter();
            db = new customerDataContext();
            cust = new CustomerTB();
            cust = (from c in db.CustomerTBs where c.ID == txtboxretrivematno.Text select c).Single<CustomerTB>();
            txtboxretrievename.Text = cust.name;
            retrevedPix = cust.photo.ToArray();
           pictureBoxretrive.Image=(Image)imageconvert.ConvertFrom(retrevedPix);
            pictureBoxretrive.SizeMode=PictureBoxSizeMode.StretchImage;
        }
