我想获取Service1URL以string[] repositoryUrls = { ... }c 开头的key 的值并将值传递给我的C#类.我怎样才能做到这一点?
我试过这样的东西,但无法获取值:
foreach (string key in ConfigurationManager.AppSettings)
{
if (key.StartsWith("Service1URL"))
{
string value = ConfigurationManager.AppSettings[key];
}
string[] repositoryUrls = { value };
}

无论是我做错了还是错过了什么.真的很感激任何帮助.

我会用一点LINQ:
string[] repositoryUrls = ConfigurationManager.AppSettings.AllKeys
.Where(key => key.StartsWith("Service1URL"))
.Select(key => ConfigurationManager.AppSettings[key])
.ToArray();

您将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();
