在C#中使用process.kill()关闭了word文档，但在打开新的word文档时，它会打开上次保存的word文档。我想要新的word文档窗口

Process wordProcess = Process.GetProcessesByName("WINWORD").FirstOrDefault();
if (wordProcess != null)
{
    wordProcess.CloseMainWindow();
    wordProcess.WaitForExit(3000); // 等待3秒
    if (!wordProcess.HasExited)
    {
        wordProcess.Kill();
    }
}

string tempPath = Path.GetTempPath();
string[] tempFiles = Directory.GetFiles(tempPath, "*.tmp", SearchOption.AllDirectories);
foreach (string tempFile in tempFiles)
{
    try
    {
        File.Delete(tempFile);
    }
    catch (Exception ex)
    {
        // 处理异常，例如文件被占用
        Console.WriteLine($"无法删除文件 {tempFile}: {ex.Message}");
    }
}

Application wordApp = new Application();
Document doc = wordApp.Documents.Open("path_to_your_document.docx");
// 进行操作...
doc.Close();
wordApp.Quit();

// 释放COM对象
Marshal.ReleaseComObject(doc);
Marshal.ReleaseComObject(wordApp);

Process[] processes = Process.GetProcessesByName("WINWORD");
foreach (Process process in processes)
{
    process.Kill();
    process.WaitForExit(); // 等待进程完全退出
}
