To install Puppeteer-Sharp in a .NET project, you'll need to use NuGet, which is the package manager for .NET. Puppeteer-Sharp is a .NET port of the Node library Puppeteer which provides a high-level API to control headless Chrome or Chromium over the DevTools Protocol.
Here's how you can install Puppeteer-Sharp in your .NET project:
Using Visual Studio:
- Package Manager Console:
Open the Package Manager Console by going to
Tools
->NuGet Package Manager
->Package Manager Console
and then run the following command:
Install-Package PuppeteerSharp
- NuGet Package Manager:
- Right-click on your project in the Solution Explorer and select
Manage NuGet Packages
. - Switch to the
Browse
tab and search forPuppeteerSharp
. - Find the PuppeteerSharp package in the list and click
Install
.
- Right-click on your project in the Solution Explorer and select
Using .NET CLI:
If you prefer to use the command line, you can use the .NET CLI to add the package. Open your command prompt or terminal and navigate to the directory that contains your project file (.csproj
). Run the following command:
dotnet add package PuppeteerSharp
Using .csproj File:
You can also manually add the dependency by editing your .csproj
file. You'll need to add a PackageReference
to the ItemGroup
that's for PackageReference
items. Here's an example:
<Project Sdk="Microsoft.NET.Sdk.Web">
<!-- ... other settings ... -->
<ItemGroup>
<!-- ... other package references ... -->
<PackageReference Include="PuppeteerSharp" Version="x.x.x" />
</ItemGroup>
<!-- ... other settings ... -->
</Project>
Replace x.x.x
with the specific version of Puppeteer-Sharp you wish to use. After saving the file, you can run dotnet restore
to install the package.
After Installing:
Once you have installed Puppeteer-Sharp, you can start using it in your project. Here's a simple example of how to use Puppeteer-Sharp to take a screenshot of a webpage:
using System;
using System.Threading.Tasks;
using PuppeteerSharp;
class Program
{
public static async Task Main(string[] args)
{
// Download the Chromium revision if it does not already exist
await new BrowserFetcher().DownloadAsync(BrowserFetcher.DefaultRevision);
// Launch the browser
using var browser = await Puppeteer.LaunchAsync(new LaunchOptions
{
Headless = true // Launches Chrome in headless mode.
});
// Create a new page
using var page = await browser.NewPageAsync();
// Navigate to the URL
await page.GoToAsync("http://example.com");
// Take a screenshot of the page
await page.ScreenshotAsync("screenshot.png");
Console.WriteLine("Screenshot captured.");
}
}
Make sure you have the using PuppeteerSharp;
directive at the top of your file to reference the Puppeteer-Sharp namespace.
Remember that Puppeteer-Sharp may require a specific version of the .NET runtime, so make sure your project is compatible with the requirements of the package.
