Question

我目前正在开发一台无法调试的机器此时，我正在尝试使用我的Web应用程序执行一些与电子邮件相关的事务。

发送电子邮件
从功能邮箱中检索电子邮件

出于某种原因，两者似乎都无法执行。我编写了这些代码块，看看我是否可以启动并运行

SendEmails部分msg.Send()功能崩溃了。我记录了msg.ToRecipients.Address，msg.Subject和msg.Body，并且我们都填写了我需要的数据。

GetEmailsFromFolder功能在点击FindItemsResults<Item> results = service.FindItems(inbox, fView);

public static ExchangeService CreateConnection()
{
    string url = WebConfigurationManager.AppSettings["EWSAsmxUrlNp"];

    //ServicePointManager.ServerCertificateValidationCallback = delegate(
    //    Object obj,
    //    X509Certificate certificate,
    //    X509Chain chain,
    //    SslPolicyErrors errors)
    //{
    //    return true;
    //};

    ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010_SP2);
    service.Url = new Uri(url);

    //service.UseDefaultCredentials = true;
    service.Credentials = new WebCredentials(@"DOM\User1", "password");

    return service;
}

public static void SendEmails(string to, string subject, string body)
{
    ExchangeService service = CreateConnection();

    EmailMessage msg = new EmailMessage(service);
    msg.ToRecipients.Add(to);
    msg.Subject = subject;
    msg.Body = new MessageBody(BodyType.HTML, body);
    msg.Send();
}

public static FindItemsResults<Item> GetEmailsFromFolder(Mailbox mailbox)
{
    ExchangeService service = CreateConnection();

    FolderView fView = new FolderView(100);
    fView.PropertySet = new PropertySet(BasePropertySet.IdOnly, FolderSchema.DisplayName);
    FolderId inbox = new FolderId(WellKnownFolderName.Inbox, mailbox.ToString());
    FindItemsResults<Item> results = service.FindItems(inbox, fView);

    return results;
}

我想在CreateConnection()函数中，url是正确且有效的，因为当我在浏览器中运行它并在输入我的凭据后，我得到以下XML返回:(只有一个小的复制粘贴）< / p>

注意1：其他位置有一台Exchange服务器。每个人都使用他们的凭据登录并访问他们的帐户。

注意2：在两次崩溃的情况下，我都会遇到以下异常（我设法记录）：

Microsoft.Exchange.WebServices.Data.ServiceRequestException：The 从服务收到的响应不包含有效的XML。 System.Xml.XmlException：缺少根元素。在 System.Xml.XmlTextReaderImpl.Throw（Exception e）at System.Xml.XmlTextReaderImpl.ParseDocumentContent（）at System.Xml.XmlTextReader.Read（）中的System.Xml.XmlTextReaderImpl.Read（）在System.Xml.XmlCharCheckingReader.Read（）处 Microsoft.Exchange.WebServices.Data.EwsXmlReader.Read（）at Microsoft.Exchange.WebServices.Data.EwsXmlReader.Read（XmlNodeType nodeType）at Microsoft.Exchange.WebServices.Data.ServiceRequestBase.ReadXmlDeclaration（EwsServiceXmlReader 读者）---内部异常堆栈跟踪结束--- at Microsoft.Exchange.WebServices.Data.ServiceRequestBase.ReadXmlDeclaration（EwsServiceXmlReader 读者） Microsoft.Exchange.WebServices.Data.ServiceRequestBase.ReadSoapFault（EwsServiceXmlReader 读者） Microsoft.Exchange.WebServices.Data.ServiceRequestBase.ProcessWebException（引发WebException webException）at Microsoft.Exchange.WebServices.Data.ServiceRequestBase.GetEwsHttpWebResponse（IEwsHttpWebRequest 请求） Microsoft.Exchange.WebServices.Data.ServiceRequestBase.ValidateAndEmitRequest（IEwsHttpWebRequest＆安培; 请求） Microsoft.Exchange.WebServices.Data.MultiResponseServiceRequest1.Execute（）在 Microsoft.Exchange.WebServices.Data.ExchangeService.InternalCreateItems（IEnumerable1 items，FolderId parentFolderId，Nullable1 messageDisposition， Nullable1 sendInvitationsMode，ServiceErrorHandling errorHandling）at Microsoft.Exchange.WebServices.Data.Item.InternalCreate（FolderId parentFolderId，Nullable1 messageDisposition，Nullable1 sendInvitationsMode）at Microsoft.Exchange.WebServices.Data.EmailMessage.InternalSend（FolderId parentFolderId，MessageDisposition messageDisposition）at Microsoft.Exchange.WebServices.Data.EmailMessage.Send（）at T.App.Factory.Helper.ExchangeWebServiceHelper.SendEmails（String to，字符串主题，字符串主体） D：\ T.App \ Factory \ Helper \ ExchangeWebServiceHelper.cs：第77行 PADAccountSwitching.App.Factory.NewBankFactory.DownloadRequests（）in D：\ T.App \ Factory \ NewBankFactory.cs：第313行

无法在C＃中使用EWS发送或阅读电子邮件
