javascript - 如何在Electron.net中接收多个参数

我想收到带有多个参数的ipcRenderer.send消息。 JavaScript看起来像这样:

document.getElementById("btn-submit").addEventListener("click", () => {
                ipcRenderer.send("btn-submit", [document.getElementById("uid").nodeValue, document.getElementById("pw").nodeValue]);
            });

当我尝试创建位于 Controller 内的监听功能时，当我将args引用为数组时会收到语法错误，如下所示:

Electron.IpcMain.On("btn-submit", async (args) =>
                {
                    MessageBoxOptions options = new MessageBoxOptions(String.Format("UID: {0} PW:{1}",args[0],args[1]))
                    {
                        Type = MessageBoxType.info,
                        Title = "Information",
                        Buttons = new string[] { "Yes", "No" }
                    };

                    var result = await Electron.Dialog.ShowMessageBoxAsync(options);
                });

如何在ipcMain监听方法中接收从ipcRenderer.send方法传递的多个参数？

最佳答案

尽管.On(...)带有Action<object>，但是当有多个参数时，您可以将object强制转换为List<object>，这将解决您的语法问题:

Electron.IpcMain.On("btn-submit", async (args) =>
                {
                    var listArgs = (List<object>)args;
                    MessageBoxOptions options = new MessageBoxOptions(String.Format("UID: {0} PW:{1}",listArgs[0],listArgs[1]))
                    {
                        Type = MessageBoxType.info,
                        Title = "Information",
                        Buttons = new string[] { "Yes", "No" }
                    };

                    var result = await Electron.Dialog.ShowMessageBoxAsync(options);
                });
