對於下面的「項目」，解決Unity for DI時，我遇到了一個非常惱人的和莫名其妙的錯誤。Unity：無法構建LogWriter類型
InvalidOperationException - 無法構造LogWriter類型。 您必須配置容器以提供此值。
？ex.Message; 「解析依賴項失敗，類型= \」WindowsFormsApplication1.Performance \「，名稱= \」（none）\「。\ r \ n異常發生while：解析。\ r \ n異常 is：InvalidOperationException - 類型LogWriter不能爲 構建。您必須配置容器以提供此值 值。\ r \ n ----------------------------- ------------------ \ r \ n在例外情況的 時間，容器是：\ r \ n \ r \ n正在解決 WindowsFormsApplication1.Performance，（none） \ r \ n解析參數 構造函數「lw \」 WindowsFormsApplication1.Performance（Microsoft.Practices.EnterpriseLibrary.Logging.LogWriter lw， Microsoft.Practices.EnterpriseLibrary.Exceptio nHandling.ExceptionManager EM）\ r \ n解決 Microsoft.Practices.EnterpriseLibrary.Logging.LogWriter，（無）\ r \ n」個

在一種形式中：
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
try
{
IUnityContainer container = new UnityContainer();
Performance p = container.Resolve<Performance>();
}
catch (Exception ex)
{
}
}
相關性類：
public class Performance
{
public Performance(LogWriter lw, ExceptionManager em)
{
}
}

Arhhhhhhhhh !!!真棒。謝了哥們。 – rism
對於其他人，這是我需要做的所有事情：var container = new UnityContainer（）。AddNewExtension（）; –

我花了一些時間弄清楚，但這個答案是非常有幫助的。如果有人想在unity.config文件中聲明它，這是應該如何完成的： –
