我正在编写一个c#类库,需要能够从web读取设置。config或app.config文件(取决于DLL是否从ASP. config引用。NET web应用程序或Windows窗体应用程序)。
我发现
ConfigurationSettings.AppSettings.Get("MySetting")
但该代码已被微软标记为弃用。
我读到我应该使用:
ConfigurationManager.AppSettings["MySetting"]
但是,在c#类库项目中,System.Configuration.ConfigurationManager类似乎不可用。
最好的方法是什么?
对于如下所示的示例app.config文件:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings>
<add key="countoffiles" value="7" />
<add key="logfilelocation" value="abc.txt" />
</appSettings>
</configuration>
使用下面所示的代码读取上述应用程序设置:
using System.Configuration;
您可能还需要添加对System的引用。在您的项目中配置(如果还没有的话)。然后你可以像这样访问这些值:
string configvalue1 = ConfigurationManager.AppSettings["countoffiles"];
string configvalue2 = ConfigurationManager.AppSettings["logfilelocation"];
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);
}
