C#实现微信自动发送消息_c#发送微信消息

看到大家对于这部分微信自动发送消息实际运行时遇到很多问题，目前微信的界面也变了，这部分代码已经不再适用了。因此针对现在微信界面重新调整了代码。目前适配的微信版本是3.9.6.33。使用依赖如下
.NetFramework 4.8
FlaUI.UIA3 4.0.0
编译好的执行文件
最新源码
FlaUI.UIA3再结合inspect.exe来进行编程，可以支持很多桌面程序的自动化，大家可以自行发挥
代码如下：

using FlaUI.Core;
using FlaUI.Core.AutomationElements;
using FlaUI.Core.Conditions;
using FlaUI.Core.Definitions;
using FlaUI.Core.Input;
using FlaUI.Core.WindowsAPI;
using FlaUI.UIA3;
using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Linq;
using System.Runtime.InteropServices;
using System.Text;
using System.Threading;
using System.Threading.Tasks;



class Program
{
    [DllImport("user32.dll", CharSet = CharSet.Auto)]
    public static extern bool SwitchToThisWindow(IntPtr hWnd, bool fAltTab);


    [STAThread]
    static void Main(string[] args)
    {
        //微信主界面窗口从左向右分3分窗口，可以使用inspect.exe  程序来看实际窗口，控件排列
        string target = "文件传输助手";
        string sendMsg = "hello  this is a test " + DateTime.Now.ToString();
        if (args.Length != 2)
        {
            Console.WriteLine("=======================================================================");
            Console.WriteLine("WebChatAuto  联系人  发送消息");
            Console.WriteLine("注意：联系人和发送消息需要使用双引号包括");
            Console.WriteLine("示例：WebChatAuto \"文件传输助手\"  \"Hello WebChat\"");
            Console.WriteLine("=======================================================================");
        }
        else
        {
            target = args[0];
            sendMsg = args[1];
        }

        Process[] processes = Process.GetProcessesByName("WeChat");
        if (processes.Count() != 1)
        {

        }
        else

                    //窗口置顶显示  避免其它窗口遮挡影响后续操作
                    IntPtr handle = processes.First().MainWindowHandle;
                    SwitchToThisWindow(handle, true);    // 激活，显示在最

以下是之前写的内容及代码。

搞定pywinauto微信自动发送消息后，看到是使用的UIA,然后看到FlaUI。好吧，C#也能做，然后就开干了。具体代码如下：

    class Program
    {
        [STAThread]
        static void Main(string[] args)
        {
            Process[] processes= Process.GetProcessesByName("WeChat");
            if(processes.Count() != 1)
            {
                Console.WriteLine("微信未启动或启动多个微信");
            }
            else
            {
                //1.附加到微信进程
                using (var app = Application.Attach(processes.First().Id))
                {
                    using (var automation = new UIA3Automation())
                    {

                        //2.获取主界面
                        var mainWindow = app.GetMainWindow(automation);
                        Console.WriteLine("获取主界面");
                        //3.切换到通讯录
                        var elements = mainWindow.FindAll(FlaUI.Core.Definitions.TreeScope.Subtree, TrueCondition.Default);
                        var addressBook = mainWindow.FindFirstDescendant(cf => cf.ByName("通讯录"));
                        addressBook.DrawHighlight(System.Drawing.Color.Red);
                        Console.WriteLine("点击通讯录");
                        addressBook.Click();

                        4.搜索
                        string target = "文件传输助手";
                        var searchTextBox = mainWindow.FindFirstDescendant(cf => cf.ByName("搜索")).AsTextBox();
                        searchTextBox.Click();
                        Keyboard.Type(target);
                        Keyboard.Type(VirtualKeyShort.RETURN);
                        Console.WriteLine("搜索目标对象");

                        //5.切换到对话框
                        Thread.Sleep(500);
                        
                        var searchList= mainWindow.FindFirstDescendant(cf=>cf.ByName("搜索结果"));
                        if (searchList != null)
                        {
                            var searchItem = searchList.FindAllDescendants().FirstOrDefault(cf => cf.Name == target && cf.ControlType == FlaUI.Core.Definitions.ControlType.ListItem);
                            searchItem?.DrawHighlight(System.Drawing.Color.Red);
                            searchItem?.AsListBoxItem().Click();
                        }
                        else
                        {
                            Console.WriteLine("没有搜索到内容");
                        }
                        Thread.Sleep(500);
                        //6.输入文本
                        string sendMsg = "hello  this is a test "+DateTime.Now.ToString();
                        var msgInput = mainWindow.FindFirstDescendant(cf => cf.ByName("输入")).AsTextBox();
                        msgInput?.Click();
                        System.Windows.Forms.Clipboard.SetText(sendMsg);
                        Keyboard.TypeSimultaneously(new[] { VirtualKeyShort.CONTROL, VirtualKeyShort.KEY_V });
                        var sendBtn= mainWindow.FindFirstDescendant(cf=>cf.ByName("发送(S)"));
                        sendBtn?.DrawHighlight(System.Drawing.Color.Red);
                        sendBtn?.Click();

                    }
                }
                 

            }

            Console.ReadLine();
        }
