Generative Completion

One of the easiest way to generate code with JetBrains Rider is to use code completion - all you need to do is to type several characters. Code generation suggestions are included in the lists of Automatic completion and Basic completion.

Here are a few examples of how you can generate code with code completion.

Overriding and implementing members

In the example below, code completion helps create an override for a virtual member from a base class. Start typing the method name and you will get a suggestion to override it in the current type:

JetBrains Rider: Compeltion suggestion for method override

After you accept the suggestion, the method body with the default implementation expands in the editor:

public class Derived : BaseClass
{
    protected override void DoSomething(int x, string s)
    {
        base.DoSomething(x, s);
    }
}
        

Properties for fields

To generate properties for a field, start typing the name of the field. JetBrains Rider will suggest to create a read-only or a read-write property with the corresponding name according to your naming style:

JetBrains Rider: Completion suggestion to generate a property for a field

After you accept the suggestion, the property body expands in the editor:

public class Properties
{
    private int _myField;

    public int MyField
    {
        get { return _myField; }
        set { _myField = value; }
    }
}
        

Type constructors

Depending on the existing members of the current type, JetBrains Rider suggests different constructors in the completion list. To create a constructor, type ctor. In the completion list, you may see the following suggestions:

ctor — a constructor without parameters
ctorf — a constructor that initializes all fields
ctorp — a constructor that initializes all auto-properties
ctorfp — a constructor that initializes all fields and auto-properties

In the example below, all kinds of constructors are available.

JetBrains Rider: IntelliSense for generating constructors.

If you accept the ctorfp suggestion, the constructor expands in the editor:

public class Person
{
    private string age;
    public string Name { get; set; }

    public Person(string age, string name)
    {
        this.age = age;
        Name = name;
    }
}
        

Templates in completion lists

All your live templates appear in the completion list. Templates are identified by their shortcuts (here are the list of shortcuts of predefined templates). You can recognize them by the corresponding icon .

For example, to invoke the public static void Main template, type its shortcut psvm:

After you accept the suggestion, the Main method expands in the editor:

public static void Main(string[] args)
{

}
