Generating Code with Code Completion

One of the easiest way to generate code with ReSharper 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:

Generating overriding and implementing members
Generating properties for fields
Generating type constructors
Live templates in completion lists

Generating 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 to ger the suggestion to override it in the current type:

/help/img/dotnet/2017.1/Coding_Assistance__Code_Completion__Generative__generative_completion_01.png

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);
    }
}

Generating properties for fields

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

/help/img/dotnet/2017.1/Coding_Assistance__Code_Completion__Generative__generative_completion_04.png

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; }
    }
}

Generating type constructors

Depending on the existing members of the current type, ReSharper 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 properties
ctorfp - a constructor that initializes all fields and properties

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

/help/img/dotnet/2017.1/Coding_Assistance__Code_Completion__Generative__generative_completion_05.png

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;
    }
}

Live 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:

/help/img/dotnet/2017.1/Reference__Options__Templates__Live_Templates__Predefined__CSharp__Other__psvm__before.png

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

public static void Main(string[] args)
{

}

This feature is supported in the following languages/technologies:

C#	VB.NET	C++	HTML	ASPX	Razor	JavaScript	TypeScript	CSS	XML	XAML	RESX	Build Scripts	Protobuf	JSON

The instructions and examples given here address the use of the feature in C#. For details specific to other languages, see corresponding topics in the ReSharper by Language section.
