Using values from AppConfig file in C#

Samuel Fernandes 2078 28-Jan-2014

selenium = new DefaultSelenium(

    ConfigurationManager.AppSettings["TestMachine"].ToString(),

    4444,      

    ConfigurationManager.AppSettings["Browser"].ToString(),       

    ConfigurationManager.AppSettings["URL"].ToString()

);

Is there an efficient way to do this, instead of repeating:

ConfigurationManager.AppSettings[""].ToString()

Hi Samuel,

I think a better idea is to write a wrapper class to everything that deals with configuration, especially if you write tests. A simple example might be:

public interface IConfigurationService
{
    string GetValue(string key);
}

This approach will allow you to mock your configuration when you need it and reduce complexity

So you could proceed with:

public void SelTest(IConfigurationService config)
{
    var selenium = new DefaultSelenium(config.GetValue("TestMachine"),
        4444, config.GetValue("Browser"), config.GetValue("URL"));
}

or you could inherit your configuration from a List and reduce the typing to:

config["Browser"]
