问题描述

I'm trying to display a value of a List<object> in a label text. I have created a List Box, where I have loaded the values of the List<Object>. Now I want the label to display the selected value of the List<object> when it's clicked in the List Box.

I have tried using label1.Text = frm.CityName.ToString(); but it returns an error

public  void WeatherReport_Load(object sender, EventArgs e)
{
    ForecastForm frm = new ForecastForm();
    List<ForecastForm> fWeather = new List<ForecastForm>();
    fWeather.Add(new ForecastForm
    {
        CityName = "Cape Town",
        dateTime = new DateTime(2019, 01, 01),
        MinTemp = 15,
        MaxTemp = 25,
        cPrep = 80,
        cHumid = 60,
        WindSpeed = 154
    });

    foreach (ForecastForm details in fWeather)
    {
        lstCityNames.Items.Add(String.Format(details.CityName));
    }
}

private void lstCityNames_SelectedIndexChanged(object sender, EventArgs e)
{
    wReport.Text = string.Join(",", x.CityName.Select(x => x.CityName).ToList());
}

How to close the browser each time after executing a scenario and launching the url again on running the next scenario?

I am using protractor-cucumber -typescript framework where in my requirement is to run 2 scenarios from a feature file. After executing one scenario, it should close the browser and then again launch the URL in the browser and run the second scenario. I understand that I have to update accordingly in my hooks file, but unable to identify it.

I have tried calling the browser.get("URL"); in the beforeEach scenario and closing the browser (ie) browser.quit(); in afterEach but that didn't work(VError: after each hook errored).

hooks.ts:

const { BeforeAll, After, Before, Status } = require("cucumber");
import * as fs from "fs";
import { browser } from "protractor";
import { config } from "../config/config";
import { async } from "q";
import { AfterAll } from "cucumber";

BeforeAll({ timeout: 1000 * 1000 }, async () => {
    await browser.get(config.baseUrl);
});

After(async function (scenario) {
    if (scenario.result.status === Status.FAILED) {
        // screenShot is a base-64 encoded PNG
        const screenShot = await browser.takeScreenshot();
        this.attach(screenShot, "image/png");
    }
    else {
        var attach = this.attach;
        return browser.takeScreenshot().then(function (png) {
            var decodedImage = new Buffer(png, "base64");
            return attach(decodedImage, "image/png");
        })
    }
});

AfterAll({ timeout: 1000 * 1000 }, async () => {
    await browser.quit();
});

config.ts:

import * as path from "path";
import { browser, Config } from "protractor";
import { Reporter } from "../support/reporter";
const jsonReports = process.cwd() + "/reports/json";
export const config: Config = {

    seleniumAddress: "http://127.0.0.1:4444/wd/hub",

    SELENIUM_PROMISE_MANAGER: false,
    baseUrl: "url",
    capabilities: {
        browserName: "chrome",
    },
    framework: "custom",
    frameworkPath: require.resolve("protractor-cucumber-framework"),

    specs: [
        "../../features/*.feature",
    ],

    onPrepare: () => {
        browser.ignoreSynchronization = true;
        browser.manage().window().maximize();
        browser.manage().deleteAllCookies();
        browser.manage().timeouts().implicitlyWait(20000);
        Reporter.createDirectory(jsonReports);
    },

    cucumberOpts: {
        compiler: "ts:ts-node/register",
        format: "json:./reports/json/cucumber_report.json",
        require: ["../../typeScript/stepdefinitions/*.js",
            "../../typeScript/support/*.js"],
        strict: true,

        tags: "(@Scenario1 or @Scenario2 )",
    },
    onComplete: () => {
        Reporter.createHTMLReport();
    },
};

Expected is to close the browser after each scenario and launch the URL and run the next scenario as each of the scenarios are a different page altogether.

解决方案

当我单击列表框中的元素时，它应该在标签中显示列表的所有元素

您的实际数据在列表框中lstCityNames，因此将此列表框中的项目转换为字符串，string.Join您可以在 Label 控件中显示所有Items以逗号 ( ,) 分隔的字符串。

所以试试下面，

private void lstCityNames_SelectedIndexChanged(object sender, EventArgs e)
{
    wReport.Text = string.Join(",", lstCityNames.Items.Cast<String>().ToList());
}
