如何在Electron.net中接收多个参数

Question

我想接收包含多个参数的ipcRenderer.send消息。JavaScript看起来如下所示：

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

当我试图创建位于控制器内的侦听函数时，当我将args引用为数组时，会收到一个语法错误，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);
                });

如何接收从ipcRenderer.send方法在ipcMain侦听方法中传递的多个参数？

尽管.On(...)采用Action<object>，但当存在多个参数时，可以将object转换为List<object>，这将修复语法问题：

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);
                });
