本文介绍了两种方法在C#中获取运行的窗体标题，特别是WPF应用窗体。方法1利用PInvoke调用Windows API，遍历任务栏结构来获取窗口标题，但可能会包含额外的后台进程。方法2通过遍历窗口句柄并检查属性来获取应用程序标题，适用于WinForms但可能不适用于WPF。文章提供了详细代码示例和来源链接。

方法1：

using System; using System.Collections.Generic; using System.Linq; using System.Text; 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.Shapes; using System.Runtime.InteropServices; namespace Backup { /// <summary> /// Window1.xaml 的交互逻辑 /// </summary> public partial class Window1 : Window { public Window1() { InitializeComponent(); } private void button1_Click(object sender, RoutedEventArgs e) { System.Diagnostics.Debug.Print("【】【】【】BEGIN【】【】【】【"); IntPtr vHandle = FindWindow("Shell_TrayWnd", null); vHandle = FindWindowEx(vHandle, IntPtr.Zero, "ReBarWindow32", null); vHandle = FindWindowEx(vHandle, IntPtr.Zero, "MSTaskSwWClass", null); vHandle = FindWindowEx(vHandle, IntPtr.Zero, "ToolbarWindow32", null); int vCount = SendMessage(vHandle, TB_BUTTONCOUNT, 0, 0); uint vProcessId; GetWindowThreadProcessId(vHandle, out vProcessId); IntPtr vProcess = OpenProcess(PROCESS_VM_OPERATION | PROCESS_VM_READ | PROCESS_VM_WRITE, false, vProcessId); IntPtr vPointer = VirtualAllocEx(vProcess, IntPtr.Zero, 0x1000, MEM_RESERVE | MEM_COMMIT, PAGE_READWRITE); char[] vBuffer = new char[256]; uint vNumberOfBytesRead = 0; try { for (int i = 0; i < vCount; i++) { SendMessage(vHandle, TB_GETBUTTONTEXTW, i, vPointer.ToInt32()); ReadProcessMemory(vProcess, vPointer, Marshal.UnsafeAddrOfPinnedArrayElement(vBuffer, 0), vBuffer.Length * sizeof(char), ref vNumberOfBytesRead);
