</appSettings>
</configuration>

C# 代码：
Console.Write(ConfigurationManager.AppSettings["name"]);
Nothing gets printed in the console. Why is this ?

below code gives you the content of active config file.
下面的代码为您提供了活动配置文件的内容。
var content = File.ReadAllLines(AppDomain.CurrentDomain.SetupInformation.ConfigurationFile);
Check what you get as content, is it contain key="name" value="Chan"or something else
?
检查你得到的content，是包含 key="name" value="Chan"还是别的什么？
if you given <add key="name" value="Chan" />then
ConfigurationManager.AppSettings["name"] should return as Chan
如果你给出 <add key="name" value="Chan" />那么 ConfigurationManager.AppSettings["name"] 应该返回为Chan

Given that your XML file (app.config) is properly formatted, try below.
Declare a variable and assign the variable the AppSettings value. Similar like-
鉴于您的 XML 文件 (app.config)格式正确，请尝试以下操作。
声明一个变量并将 AppSettings 值分配给该变量。类似的喜欢——
string sName = "";
sName = ConfigurationManager.AppSettings["name"].ToString();
