[英]How to get all the values from appsettings key which starts with specific name and pass this to any array?
In my web.config
file I have 在我的web.config
文件中
<appSettings>
<add key="Service1URL1" value="http://managementService.svc/"/>
<add key="Service1URL2" value="http://ManagementsettingsService.svc/HostInstances"/>
....lots of keys like above
</appSettings>
I want to get the value of key that starts with Service1URL
and pass the value to string[] repositoryUrls = { ... }
in my C# class. 我想获取以Service1URL
开头的key的值,并将该值传递给C#类中的string[] repositoryUrls = { ... }
。 How can I achieve this? 我该如何实现?
I tried something like this but couldn't grab the values: 我尝试了类似的方法,但无法获取值:
foreach (string key in ConfigurationManager.AppSettings)
{
if (key.StartsWith("Service1URL"))
{
string value = ConfigurationManager.AppSettings[key];
}
string[] repositoryUrls = { value };
}
Either I am doing it the wrong way or missing something here. 我可能做错了方法,或者在这里遗漏了一些东西。 Any help would really be appreciated. 任何帮助将不胜感激。
I'd use a little LINQ: 我会用一些LINQ:
string[] repositoryUrls = ConfigurationManager.AppSettings.AllKeys
.Where(key => key.StartsWith("Service1URL"))
.Select(key => ConfigurationManager.AppSettings[key])
.ToArray();
You are overwriting the array for every iteration 您正在为每次迭代覆盖数组
List<string> values = new List<string>();
foreach (string key in ConfigurationManager.AppSettings)
{
if (key.StartsWith("Service1URL"))
{
string value = ConfigurationManager.AppSettings[key];
values.Add(value);
}
}
string[] repositoryUrls = values.ToArray();
I defined a class to hold the variables I am interested in and iterate through the properties and look for something in the app.config to match. 我定义了一个类来保存我感兴趣的变量,并遍历属性并在app.config中查找要匹配的内容。
Then I can consume the instance as I wish. 然后,我可以根据需要使用该实例。 Thoughts? 有什么想法吗?
public static ConfigurationSettings SetConfigurationSettings
{
ConfigurationSettings configurationsettings = new ConfigurationSettings();
{
foreach (var prop in configurationsettings.GetType().GetProperties())
{
string property = (prop.Name.ToString());
string value = ConfigurationManager.AppSettings[property];
PropertyInfo propertyInfo = configurationsettings.GetType().GetProperty(prop.Name);
propertyInfo.SetValue(configurationsettings, value, null);
}
}
return configurationsettings;
}
