控制台应用程序可以成功读取 app.config,但是单元测试方法失败了,我无法弄清原因。两者都使用相同的 app.config 副本(未添加为链接),并且都安装了 System.Configuration.ConfigurationManager v4.4.1 NuGet 包。 App.config 文件内容如下:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<appSettings>
<add key="Test1" value ="This is test 1."/>
<add key="Test2" value ="42"/>
<add key="Test3" value ="-42"/>
<add key="Test4" value="true"/>
<add key="Test5" value="false"/>
<add key="Test6" value ="101.101"/>
<add key="Test7" value ="-1.2345"/>
</appSettings>
</configuration>
单元测试
using Microsoft.VisualStudio.TestTools.UnitTesting;
using System.Configuration;
namespace ConfigTest
{
[TestClass]
public class UnitTest1
{
[TestMethod()]
public void ConfigTest()
{
foreach (string s in ConfigurationManager.AppSettings.AllKeys)
{
System.Console.WriteLine(s);
System.Diagnostics.Debug.WriteLine(s);
}
//AllKeys.Length is 0? Should be 7...
Assert.IsTrue(ConfigurationManager.AppSettings.AllKeys.Length == 7);
}
}
}
控制台应用程序
using System;
using System.Configuration;
namespace ConfigTestApp
{
class Program
{
static void Main(string[] args)
{
foreach (string s in ConfigurationManager.AppSettings.AllKeys)
{
Console.WriteLine(s);
System.Diagnostics.Debug.WriteLine(s);
}
//Outputs 7 as expected
Console.WriteLine(ConfigurationManager.AppSettings.AllKeys.Length);
}
}
}
鉴于我对整个.NET Core世界还很陌生,我在这里做的事情完全错误吗?我现在感觉有些疯狂...
