使用反射加載泛型類的具體類型

Question

基本上，我們從產品的舊版本中獲得了一些代碼，這些代碼使用XML來驅動外部代碼的加載。

例如

ObjectHandle handle = Activator.CreateInstance(
                                         information.AssemblyName,
                                         information.TypeName);

loadedObject = (T)handle.Unwrap();

但是，當嘗試加載具有通用參數的類型時，此操作將失敗。 現在，我知道類型在編譯時將是什么（可能該類型也將是外部類型，並且可能會根據情況而改變（僅在xml中））。

有沒有一種加載類型的類的方法：其中T是ActionSettings類型的

public class MockTestRunner<T> : IRunner<T> where T : class
{
    #region IRunner<T> Members

    public T Run(string runnerXml)
    {
        MvcActionSettings mvcActionSettings = XmlSerialiser.XmlDeserialise<MvcActionSettings>(runnerXml);

        IMvcActionSettingsCreator creator = new MockPassThroughActionSettingsGenerator();
        var v = creator.Create(mvcActionSettings);
        return v as T;
    }

    public void Initialise(IWizardManagerBase manager)
    {

    }
}

    /// <summary>
/// An MVC controller settings object.
/// </summary>
[Serializable]
public class ActionSettings
{
    /// <summary>
    /// Initializes a new instance of the ActionSettings class.
    /// </summary>
    public ActionSettings()
    {
        PartialViews = new List<PartialViewEntity>();
    }

    public ActionSettings(bool endOfWizard)
    {
        EndOfWizard = endOfWizard;
    }

    public bool EndOfWizard
    {
        get;
        set;
    }}

Answer 1

嗯，一如既往的復雜。 沒意識到我應該做：

public class MockTestControllerRunner : IRunner<Interfaces.ActionSettings>
{
    #region IRunner<T> Members

    public ActionSettings Run(string runnerXml)
    {
        MvcActionSettings mvcActionSettings = XmlSerialiser.XmlDeserialise<MvcActionSettings>(runnerXml);

        IMvcActionSettingsCreator creator = new MockPassThroughActionSettingsGenerator();
        Interfaces.ActionSettings v = creator.Create(mvcActionSettings);
        return v;
    }

    #endregion

    #region IRunnerWorkflowSubscriber Members

    public void Initialise(IWizardManagerBase manager)
    {

    }

    #endregion
}

這消除了尋找與反射有關的通用參數問題的需要。
