问题 Does anyone know how to put the enableCors into the controller on vb.net. i am working along with a pluralsight course and tried a code translator with no luck. my attempt is below. <EnableCors(origins: "http://localhost:53080", headers: "*", methods: "*")> 回答1: The correct syntax would be something like this: <EnableCors("http://localhost:53080", "*","*")> The C# example appears to use named parameters. VB.NET supports that too, however the EnableCorsAttributes has properties and contractor

问题 I'm trying to get a VB regex to match only the numbers in a currency sequence without additional substitution lines if possible. It needs to look for a number with + on end $ at the start and return what's in the middle, minus any commas.
