Mugen Injection

public class ConditionTest
{
    public string Test { get; set; }

    public ConditionTest(string test)
    {
         Test = test;
    }
}

First example:

const string value = "Test";

//Create container.
var injector = new MugenInjector();
//Indicates that the binding should be used only for injections on the specified type.
injector.Bind<string>().ToConstant(value).WhenInto<ConditionTest>();

var conditionTest = injector.Get<ConditionTest>();
if (conditionTest.Test == value)
Console.WriteLine("Is always true");

try
{
    injector.Get<string>();
}
catch (Exception)
{
    Console.WriteLine("Is always true");
}

Second example:

const string value = "Test";

//Create container.
var injector = new MugenInjector();
//Indicates that the binding should be used only for injections on the specified type when namespace equals.
injector.Bind<string>().ToConstant(value).WhenNamespaceEqual("YOUR NAMESPACE");

var conditionTest = injector.Get<ConditionTest>();
if (conditionTest.Test == value)
     Console.WriteLine("Is always true");

try
{
      injector.Get<string>();
}
catch (Exception)
{
      Console.WriteLine("Is always true");
}

Third example: 
const string value = "Test";

//Create container.
var injector = new MugenInjector();
//Indicates that the binding should be used only for requests that support the specified condition.
injector.Bind<string>().ToConstant(value).When(binding => binding.TypeInto == typeof(ConditionTest));

var conditionTest = injector.Get<ConditionTest>();
if (conditionTest.Test == value)
     Console.WriteLine("Is always true");

try
{
     injector.Get<string>();
}
catch (Exception)
{
      Console.WriteLine("Is always true");
}
