How to create Key Pair?

Posted By :Abhisek Panda     Posted Date :December 28, 2009    Points :10   Category :.NET Framework 
You can create a key pair using the Strong Name tool (Sn.exe). Key pair files usually have an .snk extension. To create a key pair at the command prompt, type the following command:
sn k

In this command, file name is the name of the output file containing the key pair. The following example creates a key pair called myKey.snk.
sn -k myKey.snk

What is Private Constructor? and it's use? Can you create instance of a class which has Private Constructor?

When a class declares only private instance constructors, it is not possible for classes outside the program to derive from the class or to directly create instances of it. (Except Nested classes)
Make a constructor private if:

1) You want it to be available only to the class itself. For example, you might have a special constructor used only in the implementation of your class' Clone method.

2) You do not want instances of your component to be created. For example, you may have a class containing nothing but Shared utility functions, and no instance data. Creating instances of the class would waste memory. (More...)

Is it possible to create Cluster Index on Unique Key Column?

Unique key column by default creates a non-cluster index on the column. Primary key creates cluster index on the column. The only difference is Unique key column allows only one null value. So is it possible to have cluster index on Unique key column?

The answer is YES. Though Unique key allows null value but it still maintains the uniqueness of the column. (More...)

Is it possible to create cookies with keys? Explain using some example.

Yes, it is possible to create cookies with keys.
Cookies is a dictionary at the time of initialization, if key is specified with it. (You can determine whether cookie is dictionary or not using HasKeys property. )
For an example:

Response.Cookies("Testcookie")("key1") = "key1"
Response.Cookies("Testcookie")("key2") = "key2"

After this if you make assignment like,
Response.Cookies("Testcookie") = "noKey"
Then," key1" and "key2" of cookie("Testcookie") will be deleted. (More...)

What will you do if you need to create clustered index on more than one field? Is it possible?

The answer is yes and no.
You can create clustered index only one clustered index in table.
Either you can create index on entire table or you can create clustered index on a view covering entire table.
Suppose, you have created table with following:
CREATE TABLE [dbo].[Table1](
[field1] [int] IDENTITY(1,1) NOT NULL,
[field2] [nchar](10) ,
[field3] [nchar](10) ,
[field4] [nchar](10)
Create index on entire table:
CREATE INDEX idx_coverTable ON Table1(field1, field2) INCLUDE (field3, field4)
Create clustered index on a view covering entire table:
SELECT field1, field2, field3, field4 FROM dbo.Table1
CREATE UNIQUE CLUSTERED INDEX idx_viewClustered ON dbo.v1111(field1, field2, field3, field4)
GO (More...)
