Здравствуйте! Есть тестовое задание:
Your test task is to create a demo application for Google and Yahoo financial data.
The requirements for the application are as follows:
1. The application must be written in ASP.NET MVC
2. User should be given an option to enter quote symbol (ex.: MSFT, APPL, GOOG) and date range.
3. The application should send the parameters to a web service and get historical data in XML/CSV/JSON format.
4. User should have an ability to switch historical data provider between Google and other (or random data generator at runtime).
5. Historical data should be displayed in a table.
6. Add paging for the table.
7. The data should be updated without full page reload.
8. Show plain XML/CSV/JSON output in formatted way (optional advanced task).
For historical data providers you have to use:
1. Google historical data in CSV format.
2. Some other free web service for historical quotes data (please find it by yourself)

Как при вводе MSFT, AAPL, GOOG осуществить их поиск в интернете?

Мне нужно чтоб при вводе в textbox MSFT, APPL, GOOG моя программа сама искала информацию.
