ConfigurationSettings.AppSettings 已过时，警告 [英] ConfigurationSettings.AppSettings is obsolete, warning

问题描述

var values = new NameValueCollection
{
    { "key", ConfigurationSettings.AppSettings["API-Key"].ToString() },
    { "image", Convert.ToBase64String(File.ReadAllBytes(photo.ToString())) }
};

使用 app.config 文件的新方法是什么?

What's the new way to use the app.config file?

推荐答案

System.Configuration 中的 ConfigurationManager 类:

ConfigurationManager.AppSettings

ConfigurationManager.ConnectionStrings

因此您的代码将更改为:

So your code would change to:

var values = new NameValueCollection 
{ 
    { "key", ConfigurationManager.AppSettings["API-Key"] }, 
    { "image", Convert.ToBase64String(File.ReadAllBytes(photo.ToString())) } 
}; 

确保添加对 System.Configuration 的引用以及 System.Configuration 的 using 语句.

Make sure you add a reference to System.Configuration along with the using statement for System.Configuration.
