Execute JavaScript with Selenium WebDriver in C#

When attempting to use Selenium WebDriver to execute JavaScript in C#, developers often encounter difficulties locating the appropriate syntax. To address this, let's dive into the mechanics of executing JavaScript using C#.

In Java, executing JavaScript is accomplished through the JavascriptExecutor interface, while in C#, the corresponding interface is IJavaScriptExecutor. This simple change in naming reflects the goal of making the C# bindings feel natural to C# programmers.

To execute JavaScript in C#, utilize the following code snippet:

<code class="csharp">IWebDriver driver; // assume assigned elsewhere
IJavaScriptExecutor js = (IJavaScriptExecutor)driver;
string title = (string)js.ExecuteScript("return document.title");</code>

This code snippet retrieves the title of the web page using JavaScript. Note that the interface name, IJavaScriptExecutor, is used instead of JavascriptExecutor.
