Boxing & UnBoxing

C# provides two types of variables they are Value types and Reference Types. Value Types are stored on the stack and Reference types are stored on the heap. The conversion of value type to reference type is known as boxing and converting reference type back to the value type is known as unboxing.


class Test
    static void Main() {
        int i = 1;
        object o = i;        // boxing
        int j = (int) o;     // unboxing

SQL Azure

Microsoft® SQL Azure delivers on the Microsoft Data Platform vision of extending the SQL Server capabilities to the cloud as web-based services, enabling you to store structured, semi-structured, and unstructured data. SQL Azure will deliver a rich set of integrated services that enable you to perform relational queries, search, reporting, analytics, integration and synchronize data with mobile users, remote offices and business partners. Currently, SQL Azure offers relational database service called Microsoft® SQL Azure Database. Other services will be available in future.

As a part of the Windows Azure platform, SQL Azure Database will deliver traditional relational database service in the cloud, supporting T-SQL over Tabular Data Stream (TDS) protocol. SQL Azure Database will be available in two editions: the Web Edition Database and the Business Edition Database.

Web Edition – 2GB of T-SQL based database space for $9.99 per month
Business Edition – 10GB of T-SQL based database space for $99.99 per month.
Customers can also purchase bandwidth for $.10 in and $.15 out per GB

SQL Azure Database is on track to deliver a public CTP in August and ship in the second half of calendar year 2009. In its initial release, SQL Azure Database will support relational capabilities suitable for relational apps, including multi-tenant apps requiring large levels of scale. Future releases of SQL Azure will support advanced features like distributed queries across partitions, and auto-partition. Developers will be able to utilize existing Transact-SQL code to access their data in the cloud.

whats the Difference between Page.RegisterClientScriptBlock and Page.RegisterStartupScript

The RegisterClientScriptBlock method inserts the client-side script immediately below the opening tag of the Page object's
element. Form elements at this stage are not instantiated, so the code cannot access the form elements.

The RegisterStartupScript method inserts the specified client-side script just before the closing tag of the Page object's
element. Form elements at this stage are instantiated, so the code can access the form elements.

Retrieve Content From Web Page - Screen Scraping

To retrieve the HTML code of a URL(this process is know as Screen Scraping), .NET provides WebClient class under System.Net namespace.Here I created a sample method which takes a URL and returns the HTML code.Include System.Net & System.Text namespaces

    private string GetPageContent(string url)
string src = string.Empty;
WebClient client = new WebClient();
UTF8Encoding encoding = new UTF8Encoding();
                      src = encoding.GetString(client.DownloadData(url));
catch (Exception ex)
return src;

Close Window from CodeBehind

Page.RegisterStartupScript("CloseWin", "<script language='javascript'>{self.close();}</script>;");

When we can declare a column as Unique and Not Null both at the same time. What is the use Primary Key then?

Unique Key creates Non-Cluster index in default, But in Primary Key creates Cluster index in default.

1)unique key can be null but Primary key cant be null.

2)primary key can be referenced to other table as Foreign Key.

3)we can have multiple unique key in a table but PK is one and only one.

Primary key in itself is unique key.

Primary key which allows only unique+not null values,where has unique allow unique and null values because a null value is not equal to a null value

Whats The Difference Between string and stringbuilder


Strings are immutable and they are actually returning a modified copy of the string.


Strings are mutable there object as a buffer that can contain a string with the ability to grow from zero characters to the buffer's current capacity. Until you exceed that capacity, the string is assembled in the buffer and no object is allocated or released. If the string becomes longer than the current capacity, the StringBuilder object transparently creates a larger buffer. The default buffer initially contains 16 characters
