【问题描述】：

我正在使用 C# 语言的 Appium 使用 WinAppDriver 自动化桌面应用程序。我面临的问题是键盘交互的代码都不起作用，例如 setText、keys.ArrowDown 等。最初，它工作得很好，但从过去几天开始，它完全停止工作。 谁能建议怎么做？

using OpenQA.Selenium;
using OpenQA.Selenium.Appium.Windows;
using System;

namespace UITest

public class Test

    public string Name  get; set;  = string.Format("A_EN_0", DateTime.Now.Ticks.ToString());
    public string Description  get; set;  = string.Format("A_ED_0", DateTime.Now.Ticks.ToString());
    private readonly Records records = null;
    public Test()
    
        records = new Records();
    

    public void SetValue(string fieldName, string value = "", bool pressTab = true)
    
        string propValue;
        if (!string.IsNullOrWhiteSpace(value))
        
            propValue = value;
        
        else
        
            propValue = Common.GetPropValue(this, fieldName).ToString();
        
        switch (fieldName)
        
            case "Name":
                Common.RE7Session.FindElementByAccessibilityId("30").SendKeys(propValue);
                break;
            case "Description":
                Common.RE7Session.FindElementByAccessibilityId("18").SendKeys(propValue);
                break;
        
        if (pressTab)
        
            Common.SendKeys(Keys.Tab);
        
    

      public void AddEvent(Common.SaveOptions saveOptions = Common.SaveOptions.None)
    
        Common.RE7Session.OpenFunctionalArea("Records");
        records.OpenTask("Events");
        Common.RE7Session.FindElementByName("New Event").Click();
        Common.RE7Session.SwitchWindowWithWait(3);
        this.SetValue(nameof(this.Name));
        this.SetValue(nameof(this.Description));
        Common.RE7Session.SetText("test");
        Common.SendKeys(Keys.ArrowDown);
        Common.RE7Session.PressTab();
        Common.RE7Session.SetText(new Random().Next(10000, 99999).ToString(), false);

       

在这里，在最后一行代码中，SetText、PressTab、Key.ArrowDown，这些都不起作用。 PressTab、SendKeys的方法如下：

public static void PressTab(this WindowsDriver<WindowsElement> RE7Session, int iteration = 1)
    
        for (int i = 0; i < iteration; i++)
        
            Common.SendKeys(Keys.Tab);
        
    

public static void SendKeys(string keysToSend)
    
        System.Windows.Forms.SendKeys.SendWait(ReplaceKeyCode(keysToSend));
        Sleep(100);
    

private static string ReplaceKeyCode(string keys)
    
        keys = keys.Trim('+');
        //Action characters like tab, arrow down and etc
        keys = keys.Replace(Keys.Backspace, "BACKSPACE");
        keys = keys.Replace(Keys.Delete, "DELETE");
        keys = keys.Replace(Keys.ArrowDown, "DOWN");
        keys = keys.Replace(Keys.End, "END");
        keys = keys.Replace(Keys.Enter, "ENTER");
        keys = keys.Replace(Keys.Escape, "ESC");
        keys = keys.Replace(Keys.Help, "HELP");
        keys = keys.Replace(Keys.Home, "HOME");
        keys = keys.Replace(Keys.Insert, "INSERT");
        keys = keys.Replace(Keys.ArrowLeft, "LEFT");
        keys = keys.Replace(Keys.PageDown, "PGDN");
        keys = keys.Replace(Keys.PageUp, "PGUP");
        keys = keys.Replace(Keys.ArrowRight, "RIGHT");
        keys = keys.Replace(Keys.Tab, "TAB");
        keys = keys.Replace(Keys.ArrowUp, "UP");
        keys = keys.Replace(Keys.F1, "F1");
        keys = keys.Replace(Keys.F2, "F2");
        keys = keys.Replace(Keys.F3, "F3");
        keys = keys.Replace(Keys.F4, "F4");
        keys = keys.Replace(Keys.F5, "F5");
        keys = keys.Replace(Keys.F6, "F6");
        keys = keys.Replace(Keys.F7, "F7");
        keys = keys.Replace(Keys.F8, "F8");
        keys = keys.Replace(Keys.F9, "F9");
        keys = keys.Replace(Keys.F10, "F10");
        keys = keys.Replace(Keys.F11, "F11");
        keys = keys.Replace(Keys.F12, "F12");
        keys = keys.Replace(Keys.Add, "ADD");
        keys = keys.Replace(Keys.Subtract, "SUBTRACT");
        keys = keys.Replace(Keys.Multiply, "MULTIPLY");
        keys = keys.Replace(Keys.Divide, "DIVIDE");

        //Special Keys like control, shift and alt
        keys = keys.Replace(Keys.Control, "^");
        keys = keys.Replace(Keys.LeftControl, "^");
        keys = keys.Replace(Keys.Shift, "+");
        keys = keys.Replace(Keys.LeftShift, "+");
        keys = keys.Replace(Keys.Alt, "%");
        keys = keys.Replace(Keys.LeftAlt, "%");
        return keys;
    

库中发生了一些更改，导致直接键.[key] 不起作用。因此，我使用上述 relaceKeyCode 方法对键进行了更改。但是，这仍然行不通。

【问题讨论】：

你能解决这个问题吗？

【参考方案1】：

也许这会有所帮助：https://github.com/Microsoft/WinAppDriver/issues/134

简而言之，SendKeys(Keys.Contro + "a").，例如，e 按下控制键但不释放它。如果要释放控制键，则需要像 SendKeys(Keys.Control + "a" + Keys.Control) 一样重复。

写得好，繁荣昌盛！
