We will be create a new class in C# called Chapter9. Here, we will create various methods to illustrate the use of regex.
For the purpose of this book, we will create a simple console application to illustrate the use of regex. In reality, you would probably not have this logic mixed in with your production code, because this would result in code being rewritten. The best place to add something like regex is in a helper class within an extension method.
- Start by right-clicking the solution, going to Add, and then to New Project from the context menu:
- The Add New Project window opens up. Select the Class Library project type and call the project
Chapter9:
- After the new class file has been added, your Solution Explorer should look like this:
- Right-click the
Class1.csfile and select Rename from the context menu:
- Rename the
Class1.csfile toRecipes.csand select Yes from the confirmation dialog:
- In the console application, click on the References section and select Add Reference from the context menu:
- In Reference Manager for the console application, select
Chapter9and click on OK to add it as a reference to the console application:
- In the
Recipesclass, add the followingusingstatement so that we can use the regex assembly in .NET:using System.Text.RegularExpressions;
- After you have done all this, your
Chapter9class should look like this:using System.Text.RegularExpressions; namespace Chapter9 { public class Recipes { } }
