Any .NET examples for Yahoo Query Language (YQL)?

Question

I\'d like to make some simple calls to Yahoo Query Language (YQL). Has anyone implemented this in .NET?

Here is the query I\'d like to make from .NET:

There is a complete example (with downloadable .NET source code) here:

http://andy.edinborough.org/C-OAuth-Implementation/

This example implements OAuth to let you take advantage of the higher usage limit of 100,000 requests / day and 10,000 requests / hour.

To create an OAuth key, see So, you want to use some Yahoo! APIs.

The code won't work without a minor change: replace the query for pizza with "show tables".

Update:

YQL didn't work with without appending the following string to the query:

&env=http%3A%2F%2Fdatatables.org%2Falltables.env

The full query string is:

http://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20yahoo.finance.quotes%20where%20symbol%20in%20%28%22MSFT%22%29&diagnostics=true&env=http%3A%2F%2Fdatatables.org%2Falltables.env

To obtain a full query URL from a YQL query:

• Browse to the Yahoo YQL query console.
• Create a query, e.g. select * from yahoo.finance.quotes where symbol in ("MSFT")
• On the base of the page, there is a section under "The Rest Query". Copy this. This URL will work in any browser (or any desktop app that uses YQL).
• Modify the C# source to append the string &env=http%3A%2F%2Fdatatables.org%2Falltables.env to the url within the two overloaded QueryYahoo functions.
