Unit Testing Authorization on your Controllers

Published 4 years ago

In many of my ASP.NET web applications (mostly MVC or Web APIs) I have a mix of content with endpoints that either require authentication and authorization or that can be accessed anonymously. For example I have mostly public content (such as my own web site) with a protected management (admin) section. Or I have a Web API project with many endpoints protected by authorization but with a few of them publicly available. To ensure you protect your controllers well, you have many different options. In this article I'll show you a short unit test that you can use to ensure your controllers are properly configured when using a mixed authorization scenario.

With previous versions of ASP.NET you couldn't attach an uploaded file directly to a mail message. Instead, you needed to save the file to disk, attach it to the mail message and then when sending the message succeeded you had to clean up the old file again.

This not only meant a lot of work, it also had some security implications. Because the file needed to be written to disk, the account used by the web server required write permissions to a folder to store the attachments.

Now, with the new constructors for the Attachment class from the System.Net.Mail namespace, these problems are gone....

Filling a DataTable or DataSet the Quick Way

Published 18 years ago

In .NET 1.x filling a DataSet or a DataTable meant quite some work. You needed to create a Connection object, a DataAdapter and optionally a Command object. Then you had to call the Fill method on the DataAdapter and pass it a newly created DataSet or DataTable.

In .NET 2.0, this code model has been simplified, thanks to the Load method on the DataTable and DataSet classes that takes an IDataReader as a parameter.
