c# - Why can't new[] {AnonymousType, AnonymousType} be casted to IEnumerable? -

-

I have an anonymous type array that has been declared as: 

  Var list = new [] {New {name = "a", age = 10}, new {name = "b", age = 15}}

Is received, which implements IEnumerable fails the following: 

  convert. Type the exchange (list, typef (IEnumerable);

Also fails: 

  convert.changeTip (list, type (array));

Kind regards,

convert Change type requires implementation of IConvertible - Announcement to convert from source type to target type originally. The System.Array IConvertible does not implement the interface.

What you are trying to do is from one type to another, and (

edit:

As John It says that the artist here is contained, so an ordinary income (i.e. the underlying artist) also works as an IEnumerable.

This is my first time working with asp.net and javascript, so I do not know very good web resources, or Much about javascript debugging I have to find out that on line oFormObject.submit (); Microsoft JScript Runtime Error: Object does not support this property or method I am using the link to work as a button because I am terrible in aesthetics and I think That link will look more professional than a table of 50 buttons. I have read that this solution can cause problems with browsers due to pre-rendering of my links and many additional traffic and problems, but CSS gives me a button like a link, which has issues of alignment and difference seemed to. & lt ;!

I am trying to implement one for Delphi, but there are some problems with communication. Fitnesse will start my process, and give me a portmember as a command line argument.

-
I have a strange problem that I really do not know. In addition to developing a new ASP.NET site, I have to support the old "classic ASP" site. It is written in VBScript with a batch of JavaScript functions. Many of the JavaScript functions include 'files' Everything is fine on our production system (which security is controlled by another group - this is a military installation) Debugging them once did not work I). However, I have a fix for a vague bug that needs to be fully tested and some functions do not run under the "local" copy of the website that runs on my PC. For the record, I am running IIS 5.1 on XP. The problem is that some Javascript functions are running "OK" on the production server, but when they use it as a server, they are not defined on my PC what is happening that last Programmer, for some reason, has decided to put some functions in a series of files, which according to the observations, imitate the "need_once
