Protected configuration providers are registered in the configProtectedData section of the machine. NET Framework. The values shown here have been truncated for readability. You can configure additional protected configuration providers by adding them to the machine. You can also create your own protected configuration provider by inheriting from the ProtectedConfigurationProvider abstract base class.
The following table describes the two configuration files included with the. Both providers offer strong encryption of data. However, if you are planning to use the same encrypted configuration file on multiple servers, such as a Web farm, only the RsaProtectedConfigurationProvider enables you to export the encryption keys used to encrypt the data and import them on another server. The System. Configuration namespace provides classes to work with configuration settings programmatically.
The ConfigurationManager class provides access to machine, application, and user configuration files. If you are creating an ASP. NET application, you can use the WebConfigurationManager class, which provides the same functionality while also allowing you to access settings that are unique to ASP.
Cryptography namespace contains classes that provide additional options for encrypting and decrypting data. Use these classes if you require cryptographic services that are not available using protected configuration. Some of these classes are wrappers for the unmanaged Microsoft CryptoAPI, while others are purely managed implementations. For more information, see Cryptographic Services. This example demonstrates how to toggle encrypting the connectionStrings section in an app.
In this example, the procedure takes the name of the application as an argument, for example, "MyApplication. The app. The code uses the OpenExeConfiguration method to open the app.
The code then checks the IsProtected property, calling the ProtectSection to encrypt the section if it is not encrypted. The UnprotectSection method is invoked to decrypt the section. The Save method completes the operation and saves the changes.
You must set a reference to System. Note that in this case you can supply the relative path to the Web. The code requires a reference to the System. Configuration class.

Note You can save part of a connection string in a configuration file and use the DbConnectionStringBuilder class to complete it at run time. Note The machine.
Note Accessing configuration files at run time requires granting permissions to the caller; the required permissions depend on the type of application, configuration file, and location. Note System. But this is hard corded method for connection string. I want to change the connection string in a easy way. But when I used data set, then connection string get from application property.
Are there any solution for this situation? You might want to look at How to: Transform Web. Other than the suggestion provided by JP Hellemons to do configuration transformations, there is something else you can do, as that is only supported natively by. NET 4. Now, in order to use these without intervention each time environment is changed you can use trace constants. Say on local in Visual Studio you're compiling with the DEBUG constant set and when deploying for release it's not present, then you can do something like the following:.
