相关疑难解决方法(0)

TL; DR; 编辑6:我缩小了它并提供了5个步骤来重现问题/错误.

1. 创建VS2017 c#控制台应用程序(.Net完整框架)
2. 将方法添加到Program.cs并使该类公开:

public class Program
{
    static void Main(string[] args)
    {
    }

    public int Add(int a, int b)
    { 
        return a + b;
    }
}
}

3. 右键单击AddMethod并选择Create Unit Test:

4. 使用这些设置可以使用测试创建新的单元测试项目:

5. 添加单元测试

[TestMethod()]
public void AddTest()
{
    Program p = new Program();
    var r = p.Add(1, 2);

    Assert.IsTrue(3 == r);
}

• 测试菜单>实时单元测试>开始
• AddTest()> Live Testing> Include上的上下文菜单

现在将Add的+符号更改为-

Live Unit Testing工作,将-符号改 回+,Live Test通过!!

现在添加对Nuget DLL的引用(任何人都可以) …

我有问题.我需要在.Net Core(C#)中编写一个使用app.config的程序,如下所示:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <section name="custom" type="ConfigurationSample.CustomConfigurationSection, ConfigurationSample"/>
  </configSections>
  <connectionStrings>
    <add name="sampleDatabase" connectionString="Data Source=localhost\SQLExpress;Initial Catalog=SampleDatabase;Integrated Security=True"/>
  </connectionStrings>
  <appSettings>
    <add key="sampleApplication" value="Configuration Sample"/>
  </appSettings>
  <custom>
    <customConfigurations>
      <add key="customSample" name="Mickey Mouse" age="83"/>
    </customConfigurations>
  </custom>
</configuration>

我写道:

string connectionString = ConfigurationManager.ConnectionStrings["sampleDatabase"].ConnectionString;
Console.WriteLine(connectionString);

// read appSettings configuration
string appSettingValue = ConfigurationManager.AppSettings["sampleApplication"];
Console.WriteLine(appSettingValue);

它是来自互联网的例子,所以我认为会工作,但我得到例外:

System.Configuration.ConfigurationErrorsException: 'Error Initializing the configuration system.'
Inner Exception
TypeLoadException: Could not load type 'System.Configuration.InternalConfigurationHost' from assembly 'CoreCompat.System.Configuration, Version=4.2.3.0, Culture=neutral, PublicKeyToken=null' because the method 'get_bundled_machine_config' has no implementation …

在我的winform应用程序中,我正在尝试添加userSetting,尽管appSettings也出现了错误.当添加设置时,我得到一个抛出的异常,说:"配置系统无法初始化",内部异常"无法识别的配置部分userSetting"

例外细节:

System.Configuration.ConfigurationErrorsException was unhandled

  Source="System.Configuration"
  BareMessage="Configuration system failed to initialize"

我有一个用C#编写的.net 4.0下的控制台应用程序它有一堆变量,我想进入App.Config(所以它将在一个地方).将此部分代码添加到App.Config(配置标记之间):

<configuration>
  <appSettings>
    <add key="RemoteDirectory" value="Some Text Here"/>
  </appSettings>
</configuration>

在我的程序中尝试使用此代码进行测试

Console.WriteLine(ConfigurationManager.AppSettings["RemoteDirectory"]);

但我一直得到"配置系统初始化失败"的错误.

我在窗口应用程序中从app_config读取连接字符串时收到此异常"配置系统无法初始化"

string con = ConfigurationSettings.AppSettings["ConnectionString"].ToString();

输入以下行后在此行上

[assembly: log4net.Config.XmlConfigurator(Watch = true)]

在AssemblyInfo.cs中.如果我从Assemblyinfo.cs中删除这一行,那么我没有异常我添加此程序集用于记录目的

此刻有些慌张。我正在尝试为客户安装软件更新，但不知何故我的 WCF 服务失败并给我一条我以前从未见过的错误消息。有没有人有任何想法？
