c# - Shorten this reflection property name helper method? -

-

I want a static helper method to remove magic strings. Of course, I could pack the property method within TestContainer, which will remove the requirement to provide TestContainer as a reasoning. This is done well.

But I want to have helpful methods in a stable class, if I later decide to optimize my code and remove the method. I managed to downgrade it, but to provide a little ugly (string type, does not look very good)

Keep in mind to know any better way to "expression God", the static class should be kept universal and nothing should be known about the Test Container (otherwise it is as easy as the link provided). ) 

  Internal class Property Name Resolving {Internal Class Test Container {Public String LastName {Receive; Set; }} Internal Static Class Binding Helper {Public Stable String Property Name and Lieutenant; Tubact, TVL> (Expression & lt; Funk & Left; Tobagect, TVLux> PropertiesCycler) {var Members Expression = PropertiesThich. As a Member Member; If (member intent! = Null) leave the member Expression.member .name; And throw a new exception ("something went wrong"); }} Internal Static Zero Test () {var t = New TestContainer {LastName = "Hans"}; Console.light line (binding helper. Property name & lt; test container, string & gt; (x = & gt; x.LastName)); Console.ReadLine (); }}

BTW, the output is "lastime" and it can be used to set binding.

And another question, can I safely remove the check of the tap? 3 options for you:

  • Generate and normalize the square, and use the

  • Use an example item to estimate based on the method
  • Forget the object type completely and use only one example
    • < P> All of these are shown below. null Again to security - Expression type (you can handle methods too, BTW) - Examination to check some more code Will take 

      using the system; Using System.Linq.Expressions; Internal Category TestContainer {Public String LastName {get; Set; }} Fixed class program {static zero main () {var t = New TestContainer {LastName = "Hans"}; String s1 = binding helper & lt; Test Container & gt; . Property Name (x = & gt; x.ListName); String s2 = binding helper Property Name (T, X = & gt; x.ListName); String s3 = binding helper. Property Name ((= = gt; t.LastName); }} Internal Static Binding Binding Helper {Public Stabilized String Superman & Lt; Tubex, TLL & gt; (Tobuk template, expression & lt; funk & lieutenant; tubeckt, tvview & gt; property selector) {var member expansion = attribute. As a Member Member; If (member intent! = Null) leave the member Expression.member .name; And throw a new exception ("something went wrong"); } Public static string asset name & lt; TValue & gt; (Expression & lt; funk & lt; tvalu & gt; select property property) {var member expansion = attribute. As a Member Member; If (member intent! = Null) leave the member Expression.member .name; And throw a new exception ("something went wrong"); }} Internal Static Class Binding Helper & Lt; Tobias & gt; {Public static string communication name & lt; TValue & gt; (Expression & lt; funk & lieutenant; tubeckt, tvview & gt; property selector) {var member expression = property secretary. As a Member Member; If (Member Purpose! = Null) leave the member Expression.member .name; And throw a new exception ("something went wrong"); }}

    asp.net - Javascript/DOM Why is does my form not support submit()? -

    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 ;!

    sockets - Delphi: TTcpServer, connection reset when reading -

    -
    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. Then I should make a socket on the port number given to me, and fitness will connect to that port I am using a TCPCP server for the job: < Pre> TcpServer1.LocalPort: = ParamStr (ParamCount); TcpServer1 Active: = true; On OnEXEPT () -Event, I send the protocol version to use as specified in the protocol. Process TForm1.TcpServer1Accept (From: TOBject; ClientSocket: TCustomIpClient); Var s: ansistring; Start clientSocket. Syndrome ('slim - v 0.0', # 10); SetLength (S, 6); ClientSketts Receavebook (S, 6); End; When I call ReceiveBuf (), the process ends, and fitness throws an exception: java.net.SocketException: connection Reset I have seen what sent and received. It shows that my code sends the protocol version, fitness sends back a message, and when I try to get this message

    javascript - Classic ASP "ExecuteGlobal" statement acting differently on two servers -

    -
    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
