Read and write app.config

NET application's config file. Now comes the fun part: Only then the Save will succeed. Following class contains some default values if value is not available in configuration section. NET if you access your resources via the static properties. Another example of the path is this… C: SetAttribute "value",value ; node.

To create new configuration values you have full Designer integration within Visual Studio see picture below. There you can define one or more values to be used by your application.

GetSection "mySection" ; config. Application — is read-only at runtime; you can edit a value and have the app use without recompiling. AppSettings["Test1"]; Easy enough, right. Write "Database", "Devs", "sa" ; When the write is complete to the INI file, open the file to see the newly written values.

ConfigurationManager returns only objects with read only properties. It takes in 2 arguments i. They are really just default values that your application can access at runtime if needed. For example you can add a special MySettings.

Here is where I keep running into problems. NET config mechanism supports setting inheritance from the Machine. When you use the MySettings Feature and add a settings collection with an auto generated settings class you will receive in the Appdomain.

When I say large, I mean on the order of over printed pages. NET code, preferably VB. You had an header file with resource ids generated by the resource compiler which spits out a header file which is compiled compile time checking of the existence of resources and an object file which is linked into your target.

And because I am tired of typing and my wife is waiting for me to start a movielet's just cut to the code. Your file should look like the one below. It is basically grouping the same type of section in a group. The Application scope defines configuration values which cannot be changed by the user and are the same for all users of this application.

This constraint requires you to create every time a new instance for you e. FromName If the value is defined with a scope of User, then you can save the value back to an XML file for later retrieval.

I would recommend looking at a custom ConfigurationSection which allows you to define more complex configuration hierarchies that are strongly-typed. Well that kinda stinks, don't you think. This makes our configuration values distinguishable from other configuration values inside the App.

You have to open the config file manually and add them by "hand". Using the code Today I will show you, four different ways to get the values from configuration section. If you can take the time to read and understand the basics, you will be glad you did. AppSettings has been deprecated in favor of ConfigurationManager.

Jul 26,  · I use excel-dna to read from and write to excel with a C# interface. It seems that this is what is causing the app-config not being used. In order to test that I have created a small project with excel-dna, producing the same output as the console, but in excel.
