c# - 路径错误visual studio Selenium WebDriver

Question

我正在尝试运行一个简单的程序，但出现以下错误:

An unhandled exception of type 'OpenQA.Selenium.WebDriverException' occurred in WebDriver.dll

Additional information: Cannot find Firefox binary in PATH or default install locations. Make sure Firefox is installed. OS appears to be: Vista

代码:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using OpenQA.Selenium;
using OpenQA.Selenium.Firefox;

namespace selenium
{
    class Program
    {
           static void Main(string[] args)
        {
            IWebDriver driver = new FirefoxDriver();

            driver.Navigate().GoToUrl("http://www.reuters.com");
            driver.Manage().Window.Maximize();

            IWebElement searchInput = driver.FindElement(By.XPath("//html/body/div[10]/div[3]/div/td[1]"));
            searchInput.GetAttribute("value").ToString();

            driver.Close();           

        }
    }
}

我检查了环境变量，路径中有以下内容:

PATH=C:\Program Files\Mozilla Firefox\firefox.exe

我目前正在运行 Windows 10、Visual Studio 2015 和 selenium Webdriver 2.53.0

Answer 1

无法在 PATH 中找到 firefox 二进制文件。确保安装了 firefox C# 解决方案。

var opt = new FirefoxOptions
{
    BrowserExecutableLocation = @"c:\program files\mozilla firefox\firefox.exe"
};
var driver = new FirefoxDriver(opt);
