c# - Multiple Applications, Shared Settings: Use the registry or XML-based configuration? -


my landscape

I have an orbit library that is being called by several separately Executable Applications To gain access to this class library, it is necessary to know the address of the database server (and many other configuration options, information, etc.).

My question

set H2>

Is it common to store these specific configuration options in the Windows registry? Thing, or Class library likes to use the specific 'App.config' XML approach to the configuration tool to change it and modify it?

I am leaning towards the Registry approach, but I know that many people have opinions about not using it. What would you do?

The best practice is to use the XML configuration file in the user's% appdata% directory.

There are several reasons for this:

  1. Your application is likely to be installed in the program file. If the user has not given the administrative authority (or given) the process of your application, then you will not be able to write the file.
  2. I have worked partially in a trusted environment where the registry access is not just an option. The client completely disabled the registry permissions for the .NET runtime on that server.

  3. Your user should always have access to their own% appdata% directory. Here's a sample: 

      string configFilePath = environment. Gatefolder Path (Environmental Specialfolder. Application Data) + "myAppConfig.config"; ExeConfigurationFileMap Map = New ExeConfigurationFileMap (); Map.ExeConfigFilename = configFilePath; Configuration cfg = ConfigurationManager.OpenMappedExeConfiguration (map, configuration user .nn); Cfg.AppSettings.Settings.Add ("mySetting", "myValue!"); Cfg.Save (ConfigurationSaveMode.Modified); // MySetting = cfg.AppSettings.Settings ["mySetting"] to read the settings again. Values; // At this point, mySetting = "myValue!"

Remember to add the system. Configuration v2.0.0.0 References for your project! Default system The configuration namespace does not have all the required classes.

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
