Csharp 读取配置文件(mytest. exe. config)

我有一个项目与多个配置文件，我需要能够读取一个特定的配置文件(MyTest.exe.config).

文件看起来像这样:

<appSettings>
    <add key="Setting1" value="1.1.1.1"/>   
    <add key="Setting2" value="34567"/>   
    <add key="Setting3" value="blue"/>    
    <add key="Setting4" value="plastic"/>  
</appSettings>

代码读它看起来像这样:

try
{
    ExeConfigurationFileMap fileMap = new ExeConfigurationFileMap();
    fileMap.ExeConfigFilename = "MyTest.exe.config";
    Configuration configFile = ConfigurationManager.OpenMappedExeConfiguration(fileMap, ConfigurationUserLevel.None);
    var appSettings = configFile.AppSettings.Settings;

    if (appSettings.Count == 0)
    {
        Console.WriteLine("AppSettings is empty.");
    }
    else
    {
        foreach (var key in appSettings.AllKeys)
        {
            Console.WriteLine("Key: {0} Value: {1}", key, appSettings[key].ToString());
        }
    }
}
catch (ConfigurationErrorsException)
{
    Console.WriteLine("Error reading app settings");
}

但我只得到密钥没有值

输出:

Key: Setting1 Value: System.Configuration.KeyValueConfigurationElement
Key: Setting2 Value: System.Configuration.KeyValueConfigurationElement
Key: Setting3 Value: System.Configuration.KeyValueConfigurationElement
Key: Setting4 Value: System.Configuration.KeyValueConfigurationElement

我也try 一次获得一个值:

try
{
    String key = "Setting1";

    ExeConfigurationFileMap fileMap = new ExeConfigurationFileMap();
    fileMap.ExeConfigFilename = "MyTest.exe.config";

    Configuration configFile = ConfigurationManager.OpenMappedExeConfiguration(fileMap, ConfigurationUserLevel.None);

    var appSettings = configFile.AppSettings.Settings;
   
    string result = appSettings[key].ToString();

    Console.WriteLine(result);
}
catch (ConfigurationErrorsException)
{
    Console.WriteLine("Error reading app settings");
}

但同样的事情—输出是:

System.Configuration.KeyValueConfigurationElement 

任何帮助都是非常感激的.
