How to create, read and write Windows C # forms?
There are about three options (I assume at least .NET 3.5):
- Settings as per @Andrew
- Built-in Serialization tools that handle the fun and do some hard work for you.
- Use Linq for XML (XDocument, XElement, XAttribute, etc.), which makes it relatively trivial to manually read and write XML in whatever format you want.
In all fairness, you will probably achieve the result you want the fastest by using Linq to XML, and possibly the most flexible approach, however you should consider which is the most appropriate solution for your particular application. if the values you are storing are application settings then using config / settings might be more appropriate.

See Using Settings in C # :
The .NET Framework 2.0 allows you to create and access values that are persisted between application execution sessions. These values are called settings. Settings can represent user preferences or valuable information an application needs to use. For example, you can create a set of settings that store user preferences for the color scheme of an application. Or, you can store a connection string that specifies the database used by your application. Settings allow you to simultaneously store information that is critical to the application outside of the code and to create profiles that store the preferences of individual users.
