C# 气球提示文本：从通知中删除项目文本

我在C#中使用气球提示文本，一切都按预期进行。然而，每当我的通知出现时，就会有与项目名称相关的子文本

如何删除此文本

通知图像：

好吧，我想我至少可以给你一个开始。正如您在下图中所看到的，我设法删除了运行它的可执行文件的名称

我在这里找到了一个示例，还有来自cokeman19的示例，您可以在其中添加自己的自定义图标。虽然当您不希望可执行名称位于底部时，这似乎不起作用

如果你想做一些改变，我建议你看看，因为它提供了一些很好的提示。 这是我做了一些修改的代码，这样我们就可以得到我们想要的

                    nOTIFYICONDATA.dwInfoFlags = NIF_LARGE_ICON;
                    break;
                case ToolTipIcon.Info:
                    nOTIFYICONDATA.dwInfoFlags = 1;
                    break;
                case ToolTipIcon.Warning:
                    nOTIFYICONDATA.dwInfoFlags = 2;
                    break;
                case ToolTipIcon.Error:
                    nOTIFYICONDATA.dwInfoFlags = 3;
                    break;
            }
            int ret = Shell_NotifyIcon(1, nOTIFYICONDATA);
        }

        public void RemoveFromTray()
        {
            UpdateIcon(false);
            if (_hIcon != IntPtr.Zero)
                DestroyIcon(_hIcon);
        }

        ~NotifyIconLarge()
        {
            Dispose(false);
        }

        public void Dispose()
        {
            Dispose(true);
            GC.SuppressFinalize(this);
        }

        public void Dispose(bool disposing)
        {
            RemoveFromTray();
        }
    }

因此，首先在某处声明NotifyIconLarge类

      private NotifyIconLarge _nil;

然后使用以下代码创建通知弹出窗口：

    _nil = new NotifyIconLarge(Handle, "Icon Tip");
    _nil.ShowBalloonTip(10000, "Balloon Title", "Balloon Text", ToolTipIcon.None);

使用完托盘后，请将其卸下：

    _nil.RemoveFromTray();

大部分代码的贷项都归于cokeman19

    _nil.RemoveFromTray();
