How to Display IntelliSense Attributes' Description in Visual Studio Code?

IntelliSense is a feature in Visual Studio Code (VS Code) that provides smart completions based on variable types, function definitions, and imported modules. It can make coding more efficient by reducing the amount of typing and providing accurate suggestions.

IntelliSense attributes are a way to provide additional information about your code, such as descriptions, examples, and parameters. This information can be displayed in VS Code, making it easier to understand and use your code. In this article, we will show you how to display IntelliSense attributes' description in VS Code.

Prerequisites

Before we begin, you will need to have the following:

• Visual Studio Code installed on your computer.
• A programming language that supports IntelliSense attributes, such as C# or TypeScript.

Enabling IntelliSense Attributes

To enable IntelliSense attributes, you will need to add a comment above the code you want to document. The comment should start with three forward slashes (///) for C# or two forward slashes (//) for TypeScript, followed by the attribute name and description.

Here is an example of how to document a function in C#:

/// <summary>
/// Adds two numbers.
/// </summary>
/// <param name="a">The first number.</param>
/// <param name="b">The second number.</param>
/// <returns>The sum of the two numbers.</returns>
int Add(int a, int b)
{
    return a + b;
}

And here is an example of how to document a function in TypeScript:

// Adds two numbers.
// @param a The first number.
// @param b The second number.
// @returns The sum of the two numbers.
function add(a: number, b: number): number {
    return a + b;
}

Displaying IntelliSense Attributes' Description

To display IntelliSense attributes' description in VS Code, you will need to hover over the code you want to see the description for. This will bring up a tooltip with the attribute's description.

Here is an example of how to display the IntelliSense attributes' description for the Add function in C#:

1. Open the C# file in VS Code.
2. Place the cursor on the Add function.
3. Hover over the Add function with the mouse.
4. The tooltip will display the function's description, parameters, and return value.

Here is an example of how to display the IntelliSense attributes' description for the add function in TypeScript:

1. Open the TypeScript file in VS Code.
2. Place the cursor on the add function.
3. Hover over the add function with the mouse.
4. The tooltip will display the function's description, parameters, and return value.

Customizing IntelliSense Attributes

You can customize IntelliSense attributes by changing the attribute's name, description, and other properties. The available properties depend on the programming language you are using.

Here is an example of how to customize the Add function's IntelliSense attributes in C#:

/// <summary>
/// Calculates the sum of two numbers.
/// <param name="a" type="int">The first number.</param>
/// <param name="b" type="int">The second number.</param>
/// <returns>The sum of the two numbers.</returns>
int Add(int a, int b)
{
    return a + b;
}

Here is an example of how to customize the add function's IntelliSense attributes in TypeScript:

// Calculates the sum of two numbers.
// @param a {number} The first number.
// @param b {number} The second number.
// @returns {number} The sum of the two numbers.
function add(a: number, b: number): number {
    return a + b;
}

In this article, we have shown you how to display IntelliSense attributes' description in VS Code. By adding comments with IntelliSense attributes, you can provide additional information about your code, such as descriptions, examples, and parameters. This information can be displayed in VS Code, making it easier to understand and use your code.
