问题描述
我想在Windows上自动登录Chrome，Selenium部分已完成，但现在有一个需要自动化的窗口。链接数据按钮的调用。看起来我发现我的代码中有正确的元素，它确实尝试调用，但无济于事。

解决方案
你的代码对我来说似乎很好。
你有什么异常吗？请让我知道如果是这样的话。
如果您没有得到任何异常，Button不会以正确的方式实现InvokePattern。 （它实现的方式属于被测试的应用程序（AUT），并且更具体地指向） - 例如：提供程序告诉调用模式调用右键单击而不是左键单击后台，不能从外面改变。
解决方法（如果您无法修改AUT strong>）是使用边界矩形或clickablePoint属性。将光标移动到此位置并模拟点击（例如，通过user32.dll）。注意你的窗口在前台（这限制了你的脚本并行执行几个应用程序！）
如果你能够改变AUT，最好的深入了解UI自动化提供程序文档或查找相关教程。
I would like to automatically sign into Chrome on Windows, the Selenium part is done but now there is a Window that needs to be automated. The invocation of the Link data push button. It appears I find the right element with my code and it does attempt an invoke but to no avail.
Below snippet is from WPF :

using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
using System.Windows.Automation;
using System.Diagnostics;
using System.Runtime.InteropServices;
namespace Chrome_WPF_SSO
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
public InvokePattern GetInvokePattern(AutomationElement element)
{
return element.GetCurrentPattern(InvokePattern.Pattern) as InvokePattern;
}
public MainWindow()
{
InitializeComponent();
//1
var Chrome = Process.GetProcessesByName("chrome");
if (Chrome.Length <= 0) { }
else
{
foreach (var cp in Chrome)
{
if (!(cp.MainWindowHandle == IntPtr.Zero))
{
//To find the tabs we first need to locate something reliable - the 'New Tab' button
AutomationElement rootElement = AutomationElement.FromHandle(cp.MainWindowHandle);
System.Windows.Automation.Condition condNewTab = new PropertyCondition(AutomationElement.NameProperty, "Google Chrome");
System.Windows.Automation.Condition condCustom = new PropertyCondition(AutomationElement.NameProperty, "Link your Chrome data to this account?");
AutomationElementCollection allNames = rootElement.FindAll(TreeScope.Descendants, condCustom);
TreeWalker tWalker2 = TreeWalker.ControlViewWalker;
System.Windows.Automation.Condition LinkData = new PropertyCondition(AutomationElement.NameProperty, "Link data");
AutomationElementCollection elementscoll = rootElement.FindAll(TreeScope.Descendants, LinkData);
foreach (AutomationElement a in elementscoll)
{
if (a.Current.LocalizedControlType.ToString() == "button")
{
try
{
((InvokePattern)a.GetCurrentPattern(InvokePattern.Pattern)).Invoke();
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
}
}
}
}
}
}
}

解决方案
Your code seems just fine for me.Do you get any exception? please let me know if so.
In case you don't get any exception, the Button does not implement the InvokePattern the right way. (The way it's implemented belongs to the application under test(AUT), and to be more specific to the actually UI Automation Provider of that element.) - e.g.: the provider tells the invoke pattern to invoke right-click instead of left-click in the background which sadly can not be changed from the outside.
A work-around on that (in case you can not modify the AUT) is to use the bounding rectangle or clickablePoint propertery. Move the cursor to this location and simulate a click (by "user32.dll" for example). Take care that your window is in the foreground (which limits your script in parallel execution of several applications!)
In case you are able to change the AUT, the best is to dig into the UI Automation Provider documentation or find some tutorial on that.
