捕捉SOAP異常.NET

Question

我想如何正確地捕捉肥皂異常。我只能將它作爲system.net.webexception（Error 500 HTTP）捕獲，但不能作爲soapheaderexception或soap異常捕獲。

我當前的代碼是：

Try 
     'Code 

Catch soapExcpHeader As System.Web.Services.Protocols.SoapHeaderException 
      'Can't catch here 
      Dim error_desc As String = soapExcpHeader.Detail.OuterXml 
      Throw New System.Web.Services.Protocols.SoapHeaderException() 
Catch soapExcp As System.Web.Services.Protocols.SoapException 
      'Can't catch here 
      Dim error_desc As String = soapExcp.Detail.OuterXml 
      Throw New System.Web.Services.Protocols.SoapException 
Catch webExcp As System.Net.WebException 
      'Here I catch 
      Console.WriteLine(webExcp.ToString()) 
      Throw webExcp 
Catch ex as Exception 
      'Other types of exceptions 
      Throw ex 
End Try 

一如既往感謝您的答覆。

嘗試查看異常的GetType（）屬性的值是什麼，如果catch塊不停止在System.Web.Services.Protocols.SoapHeaderException上，則表示您的異常不會繼承它。
