Introduction to Intellisense in Visual Studio 2008

By Sateesh Arveti on Aug 23, 2009
This article explains about Visual Studio 2008 Intellisense features.

In this article, we will discuss about Intellisense features and adding those features to our classes and methods. Intellisense is a set of features provided by Visual Studio to ease our coding. We can reduce our coding time by using Intellisense in a better way. We will look into it by a sample application.

Create a console application named as IntellisenseDemo in Visual Studio 2008. VS Intellisense helps us by providing names of valid members of a class, parameter names and its types and complete declaration of an identifier in our code. First, we look each feature present in Intellisense one by one.

List Members:

We can get a list of valid members of a type like class by typing its name followed by "." as shown below:


By default, Auto list members will be enabled. We can manually List members of a type by pressing Ctrl+J.

Parameter Info:

This will give information about parameters like its type, name and number of parameters for a method as shown below:


We can invoke Parameter Info manually by using Ctrl+Shift+Space.

Quick Info:

This option will display the complete declaration of an identifier as shown below:


We can get Quick Info of an identifier by placing a cursor over it. We can manually invoke it by Ctrl+K, Ctrl+I.

Complete Word:

This option will helps us to complete a word without typing full name of it. We can type first few letters of an identifier and press Ctrl+SpaceBar to complete the word. If we have multiple matches, it will show list of matching words in List Members popup.

Adding Parameter Info details to our code:

By using XML documentation comments (///, ... in VB) for a method, we can add information for displaying in Parameter Info and Quick Info box as shown below:

        /// Appends s1 to s2 and returns it back.
        /// </summary>
        /// <param name="s1"></param>
        /// <param name="s2"></param>
        /// <returns>string</returns>
        static string TestIntellisense(string s1, string s2)
            return s1 + s2;

I am ending the things here. I hope this article will be helpful for all.
