What is the Uri class and what is its purpose and where should I use it?
Can not pass an object from it to a string variable see in the example:
String caminho = new Uri(@"c:\Windows");
Generate the following error:
Error 1 Can not implicitly convert type 'System.Uri' to 'string'
I read about that is used in strings , but I'm confused by that.
I have already replied what is URI .
In the background is a canonical "address" of a resource. And use where you need such an address. If you need an address for a web page, a file path, a reference that has a pattern of where you are and what is that.
Obviously it has a format and rules of what you can have there.
Not used in strings . It is possible to get a string generated with the contents of a URI. Like creating a URI by trying parse a string .
The syntax is clearly incorrect. You are creating an object of type Uri and trying to save it in a type String . It does not work.
documentation might help something.
