如何使用Generic對象訪問不具有共同祖先的不同對象的屬性？

Question

我有這個代碼，基本上它在「X」HttpBinding中設置了相同的屬性。

switch (serviceEndpoint.Binding.GetType().ToString()) 
{ 
case "System.ServiceModel.WSHttpBinding": 
    WSHttpBinding _wsBinding = (WSHttpBinding)serviceEndpoint.Binding; 
    _wsBinding.MaxBufferPoolSize = maxSize; 
    _wsBinding.MaxReceivedMessageSize = maxSize; 
    _wsBinding.OpenTimeout = timeOut; 
    _wsBinding.ReaderQuotas.MaxStringContentLength = maxSize; 
    break; 

case "System.ServiceModel.WebHttpBinding": 
    WebHttpBinding _webBinding = (WebHttpBinding)serviceEndpoint.Binding; 
    _webBinding.MaxBufferPoolSize = maxSize; 
    _webBinding.MaxBufferSize = maxSize; 
    _webBinding.MaxReceivedMessageSize = maxSize; 
    _webBinding.OpenTimeout = timeOut; 
    break; 

default: 
case "System.ServiceModel.BasicHttpBinding": 
    BasicHttpBinding _basicBinding = (BasicHttpBinding)serviceEndpoint.Binding; 
    _basicBinding.MaxBufferPoolSize = maxSize; 
    _basicBinding.MaxBufferSize = maxSize; 
    _basicBinding.MaxReceivedMessageSize = maxSize; 
    _basicBinding.OpenTimeout = timeOut; 
    break; 
} 

對象serviceEndpoint.Binding可能每次都不同。

我想知道，我是否可以這樣做：

object _Binding = serviceEndpoint.Binding; 
_Binding.MaxBufferPoolSize = maxSize; 
_Binding.MaxBufferSize = maxSize; 
_Binding.MaxReceivedMessageSize = maxSize; 
_Binding.OpenTimeout = timeOut; 

但如果我把這個，我有一個錯誤，因爲我沒有得到投對象的屬性。

不幸的是，這些屬性沒有在共同的祖先上定義，所以剩下的唯一方法就是使用反射。該dynamic關鍵字是一個很好的快捷方式：

dynamic binding = serviceEndpoint.Binding; 

binding.MaxBufferPoolSize = maxSize; 
binding.MaxBufferSize = maxSize; 
binding.MaxReceivedMessageSize = maxSize; 
binding.OpenTimeout = timeOut; 

但這樣做，你失去了在編譯時檢測到錯誤，投的能力。這取決於你決定是否值得。
