ASP .NET perguntas e respostas de entrevista
Pergunta 11. Explain the differences between Server-side and Client-side code?
Server-side code executes on the server.Client-side code executes in the client's browser.
Pergunta 12. What type of code (server or client) is found in a Code-Behind class?
The answer is server-side code since code-behind is executed on the server.However,
during the code-behind's execution on the server, it can render client-side code such
as JavaScript to be processed in the clients browser.But just to be clear, code-behind
executes on the server, thus making it server-side code.
Pergunta 13. Should user input data validation occur server-side or client-side?Why?
All user input data validation should occur on the server at a minimum.Additionally,
client-side validation can be performed where deemed appropriate and feasable to
provide a richer, more responsive experience for the user.
Pergunta 14. What is the difference between Server.Transfer and Response.Redirect?Why would I choose one over the other?
Server.Transfer transfers page processing from one page directly to the next page
without making a round-trip back to the client's browser.This provides a faster
response with a little less overhead on the server.Server.Transfer does not update the
clients url history list or current url.Response.Redirect is used to redirect the user's
browser to another page or site.This performas a trip back to the client where the
client's browser is redirected to the new page.The user's browser history list is
updated to reflect the new address.
Pergunta 15. Can you explain the difference between an ADO.NET Dataset and an ADO Recordset?
Valid answers are:
A DataSet can represent an entire relational database in memory, complete with
tables, relations, and views.
A DataSet is designed to work without any continuing connection to the original data
source.
Data in a DataSet is bulk-loaded, rather than being loaded on demand.
There's no concept of cursor types in a DataSet.
DataSets have no current record pointer You can use For Each loops to move
through the data.
You can store many edits in a DataSet, and write them to the original data source in
a single operation.
Though the DataSet is universal, other objects in ADO.NET come in different
versions for different data sources.
