.net - Workaround for lack of 'nameof' operator in C# for type-safe databinding? -

-

There are many emotions to include a nameof operator in C #. An example of how this operator will work will return name (customer name) string "name" .

I have a domain object. And I have to pair it. And I need the names of properties to be strings I and I want them to be type-safe.

I remember that the workaround is coming to NAT 3.5 which provides functionality of nameof and includes lambda expressions. However, I am unable to locate this solution. Can someone provide this solution for me?

If possible, then. I am also interested in implementing the functionality of the nameof in NET 2.0.

This code basically does this: 

  class programs {Static void main () {var propName = Nameof & lt; SampleClass & gt; Property (E => E. Name); Console.WriteLine (propName); }} Name of the public class & lt; T & gt; {Static String property & lt; TProp & gt; (Expression & lt; funk & lt; t, tprop & gt; & gt; expression) {var body = expression. As a member expression; If (body == faucet) throwing the new argument exception ("'expression must be a member expression'); return body.member .name;}}

(Of course this is 3.5 code. ..)

javascript - data.match(var) not working it seems -

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.) On the website, I'm trying to remove it. & lt; Span class = "robux" data-plus = "item-privatesale-price" & gt; 115 & lt; / Span & gt; Keep in mind
