捕获SOAP异常.NET

我想知道如何正确捕获soap异常。我只能将其捕获为system.net.webexception（错误500 HTTP），但不能捕获为soapheaderexception或soap异常

我目前的代码是：

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

一如既往地感谢您的回复。

尝试查看异常的GetType（）属性的值，如果您的catch块没有在System.Web.Services.Protocols.SoapHeaderException上停止，则表示您的异常没有继承它
