Hi,
first, let's talk about convert scraper from VB.NET to C#. The best way to do this is:
1, Compile the VB.NET code into assembly
2, Decompile the assembly with .NET Reflector or similar tools, view the source code in C#
3, Export the C# code
4, Fix the syntax errors and test the program to see whether it works well.
second, the google map scraper, we can also use Selenium what I think is better than WebBrowser control, because it's more convenient to locate HTML elements through WebDriver ( can use XPath and find by text), and it's convenient to do web automation through WebDriver(such as click on button, select drop down values etc)
Could you please provide detail to me? Thank you.
