Why am I getting a Soap exception?

Question

I am trying to load an attachment into a list:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using ConsoleApplication3.TestReference;
using System.IO;

namespace ConsoleApplication3
{
    class Program
    {
        static void Main(string[] args)
        {
            string srcUrl = @"C:......comp_name.xlsx";
            FileStream fStream = File.OpenRead(srcUrl);
            string fileName = fStream.Name.Substring(3);
            byte[] contents = new byte[fStream.Length];
            fStream.Read(contents, 0, (int)fStream.Length);
            fStream.Close();

            ServiceWebReference.Lists listService = new ServiceWebReference.Lists();
            listService.Credentials = System.Net.CredentialCache.DefaultCredentials;

            try
            {
                // adding attachment
                string result = listService.AddAttachment("testList", "1", fileName, contents);
                Console.WriteLine(result);
            }
            catch (System.Web.Services.Protocols.SoapException e)
            {
                Console.WriteLine(e.GetBaseException());
                Console.WriteLine(e);
            }
        }
    }
}

I get it Unhandled SOAP exception ....
Here is the complete exception I received:

System.Web.Services.Protocols.SoapException: Exception of type 'Microsoft.SharePoint.SoapServer.SoapServerException' was thrown.
  at System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse(SoapClientMessage message, WebResponse response, Stream responseStream, Boolean asyncCall)

How to debug it? What is a SOAP exception in my case?

Answer 1

Why are you using catch (System.Web.Services.Protocols.SoapException e)

1. Use ex instead of e, because e already exists as EventArgs e
2.Try. catch (SoapException ex)This is the best way.

So, concentrate on the exception handling interlocutor. Hope this helps you.
