c# - 瀑布结束问题。它提示回到其他对话框而不是结束

Question

我总共有 4 个对话。在其中一个对话框(名为“产品问题”)中，我必须进入一个名为“解决方案”的新对话框，在该对话框的末尾，它们本身处于特定条件。从产品问题中显示自适应卡，其中有 4 个选项，在“过载”、“计算机重启”、“低备份”上，它转到名为“解决方案”的新对话框，其中有两个步骤:在第一步中显示自适应卡再次用 4 个选项命名的卡片 “重启机器”，“关闭设备”，“按下，需要帮助……当我选择从第 1 步打开的任何选项三个时，如“重启机器”，“关闭设备”，“按下……它应该显示自适应卡和结束他们自己并需要帮助，它将返回到产品问题并为其显示定义的步骤。但是当我选择 “重启机器”、“关闭设备”或按 ..对话框没有结束，它又回到了产品问题。

如果你想结束一个对话框而不返回到任何之前的对话框，你需要使用CancellAllDialogs。看起来您只使用了 EndDialog，它只会结束当前事件的对话框。
