c# - 为什么我会得到 Soap 异常？

Question

我正在尝试将附件上传到列表:

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);
            }
        }
    }
}

我得到未处理的 SOAP 异常 ...。
这是我得到的完整异常:

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)
  at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters)
  at ConsoleApplication3.ServiceWebReference.Lists.AddAttachment(String listName, String listItemID, String fileName, Byte[] attachment) 
    in z:\Xxxxl\TestC\ConsoleApplication3\ConsoleApplication3\Web References\ServiceWebReference\Reference.cs:line 782
  at ConsoleApplication3.Program.Main(String[] args) 
    in z:\Xxxxl\TestC\ConsoleApplication3\ConsoleApplication3\Program.cs:line 29

如何调试它？在我的案例中，SOAP 异常是什么？

Answer 1

为什么要使用 catch (System.Web.Services.Protocols.SoapException e)

1.用ex代替e，因为e已经作为EventArgs e
存在2.尝试catch (SoapException ex)这是一个更好的方法

所以，集中精力处理异常，希望对你有帮助
