Once done, you will see a XML menu in the menu bar.Save a sample output from APIs to a XML file.C# Wrapper Classes for XML Deserialization But Visual Studio provides very easy way to accomplish this task. They sometimes end up in wrong class / variable assignment as well. In order to store the deserialized object, we need to write class files which correspond properly stores node values for XML.īut writing C# wrapper classes for large XML with numerous nodes is a tedious task. Normally, parsing XML is done by XMLSerialize.Deserialize() function. API response XMLs are complex, and can't easily be converted as such. Next comes the big work of parsing the XML from the REST API response. Weather, World geography, local US yellow pages, Google and its associated websites like news, search, Microsoft Bing, etc. Yahoo! also provides the corresponding REST query so that Webclient can utilize the URL and formulate the JSON/XML response as needed. This utilizes Yahoo! APIs eliminating the need to write complex API programming. Results of the query are either retrieved in JSON or XML as chosen. is the YQL console which has complete details on tables, sample queries. It's similar to SQL and is designed to retrieve and manipulate data from APIs through a single Web interface. Mostly APIs are required to sign up and secret keys are to be included in the request so that the server-side can understand it's a legitimate request. Who Provides APIs?Ĭompanies like Google, Yahoo!, Starbucks, Netflix and multiple others provide lot of APIs which can be utilized to get necessary information. The response is usually a JSON or XML which needs to be parsed as required for our requirement. Similarly, Web APIs are requests triggered by a client usually with a secret key for authentication.
Microsoft itself provides numerous APIs in various DLLs like user32.dll, advapi32.dll, etc. Desktop APIs are usually DLL file which have functions defined in them. What is API?ĪPI is Application Programming Interface. Yahoo! APIs provide various information like weather, geographical information like country, city, ocean details, local US complete city information etc. This tip aims at getting numerous amount of data using Yahoo! APIs using C#.
