我总是为所有配置值创建一个带有类型安全属性的IConfig接口。然后，Config实现类将调用包装到System.Configuration。整个系统。配置调用现在在一个地方，维护和跟踪正在使用的字段并声明它们的默认值变得更加容易和清晰。我编写了一组私有帮助器方法来读取和解析常见数据类型。

使用IoC框架，你可以通过简单地将接口传递给类构造函数，在应用程序中的任何地方访问IConfig字段。你还可以在你的单元测试中创建IConfig接口的模拟实现，这样你就可以测试各种配置值和值组合，而不需要触及你的App.config或Web。配置文件。

这里有一个例子:App.config

<applicationSettings>
    <MyApp.My.MySettings>
        <setting name="Printer" serializeAs="String">
            <value>1234 </value>
        </setting>
    </MyApp.My.MySettings>
</applicationSettings>

Dim strPrinterName as string = My.settings.Printer

您需要向System添加一个引用。在项目的引用文件夹中的配置。

你绝对应该使用ConfigurationManager，而不是过时的ConfigurationSettings。

我可以在。net Core项目中使用以下方法:

步骤:

Create an appsettings.json (format given below) in your project. Next create a configuration class. The format is provided below. I have created a Login() method to show the usage of the Configuration Class. Create appsettings.json in your project with content: { "Environments": { "QA": { "Url": "somevalue", "Username": "someuser", "Password": "somepwd" }, "BrowserConfig": { "Browser": "Chrome", "Headless": "true" }, "EnvironmentSelected": { "Environment": "QA" } } public static class Configuration { private static IConfiguration _configuration; static Configuration() { var builder = new ConfigurationBuilder() .AddJsonFile($"appsettings.json"); _configuration = builder.Build(); } public static Browser GetBrowser() { if (_configuration.GetSection("BrowserConfig:Browser").Value == "Firefox") { return Browser.Firefox; } if (_configuration.GetSection("BrowserConfig:Browser").Value == "Edge") { return Browser.Edge; } if (_configuration.GetSection("BrowserConfig:Browser").Value == "IE") { return Browser.InternetExplorer; } return Browser.Chrome; } public static bool IsHeadless() { return _configuration.GetSection("BrowserConfig:Headless").Value == "true"; } public static string GetEnvironment() { return _configuration.GetSection("EnvironmentSelected")["Environment"]; } public static IConfigurationSection EnvironmentInfo() { var env = GetEnvironment(); return _configuration.GetSection($@"Environments:{env}"); } } public void Login() { var environment = Configuration.EnvironmentInfo(); Email.SendKeys(environment["username"]); Password.SendKeys(environment["password"]); WaitForElementToBeClickableAndClick(_driver, SignIn); }

必须向系统添加引用。项目的配置程序集。

我发现最好的方法，以系统的方式访问应用程序设置变量，通过在系统上制作包装类。配置如下

public class BaseConfiguration
{
    protected static object GetAppSetting(Type expectedType, string key)
    {
        string value = ConfigurationManager.AppSettings.Get(key);
        try
        {
            if (expectedType == typeof(int))
                return int.Parse(value);
            if (expectedType == typeof(string))
                return value;

            throw new Exception("Type not supported.");
        }
        catch (Exception ex)
        {
            throw new Exception(string.Format("Config key:{0} was expected to be of type {1} but was not.",
                key, expectedType), ex);
        }
    }
}

现在我们可以通过硬编码的名称使用另一个类访问所需的设置变量，如下所示:

public class ConfigurationSettings:BaseConfiguration
{
    #region App setting

    public static string ApplicationName
    {
        get { return (string)GetAppSetting(typeof(string), "ApplicationName"); }
    }

    public static string MailBccAddress
    {
        get { return (string)GetAppSetting(typeof(string), "MailBccAddress"); }
    }

    public static string DefaultConnection
    {
        get { return (string)GetAppSetting(typeof(string), "DefaultConnection"); }
    }

    #endregion App setting

    #region global setting


    #endregion global setting
}
