How to set dynamic value in my Attribute

by

You could create an enum with special values, and accept them in a separate constructor overload in the attribute:

enum SpecialConfigurationValues
{
    MachineName
    // , other special ones
}

class ConfigurationKeyAttribute : Attribute
{
    private string _key;
    private string _value;

    public ConfigurationKeyAttribute(string key, string value)
    {
        // ...
    }

    public ConfigurationKeyAttribute(string key, SpecialConfigurationValues specialValue)
    {
        _key = key;
        switch (specialValue)
        {
            case SpecialConfigurationValues.MachineName:
                _value = Environment.MachineName;
                break;
            // case <other special ones>
        }
    }
}

[ConfigurationKey("MonitoringService", SpecialConfigurationValues.MachineName)]
