如何使用通用对象访问没有共同祖先的不同对象的属性？

Question

我有这段代码，基本上它在“ X” HttpBinding中设置了相同的属性。

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;
}

对象serviceEndpoint.Binding每次都可以不同。

我想知道是否可以做以下事情：

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

但是如果我放这个，我会出错，因为我没有得到演员的属性。

不幸的是，这些属性没有在公共祖先上定义，因此剩下的唯一方法是使用反射。 dynamic关键字是一个不错的捷径：

dynamic binding = serviceEndpoint.Binding;

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

但是这样做会失去在编译时检测强制转换错误的能力。 由您决定是否值得。
