Generative 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.

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:

ReSharper: 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. ReSharper will suggest to create a read-only or a read-write property with the corresponding name according to your naming style:

ReSharper: 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, 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 auto-properties

  • ctorfp— a constructor that initializes all fields and auto-properties

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

ReSharper: 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 and postfix 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 ThemedIcon LiveTemplate Screen Gray png.

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

ReSharper: Code template in completion list

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

public static void Main(string[] args) { }

When you select items in completion lists using keyboard, the selection will jump to the first item after the last item and vice versa. You can disable this behavior by clearing Loop selection around ends of a list on the Environment | IntelliSense | Completion Appearance page of ReSharper options (Alt+R O) .
