客户端SendEmail-Method不起作用

Question

我想使用SharePoint 2013客户端对象模型SendEmail-Method发送电子邮件，但我总是得到“必须指定收件人”。错误。我尝试使用不同的电子邮件地址和多个SharePoint服务器，但在所有情况下都发生了错误。

示例源（C＃）：

string webUrl = "http://sharepoint.example.com/";

EmailProperties properties = new EmailProperties();
properties.To = new string[] { "email@example.com" };
properties.Subject = "Test subject";
properties.Body = "Test body";

ClientContext context = new ClientContext(webUrl);

Utility.SendEmail(context, properties);

context.ExecuteQuery(); // ServerException thrown here
context.Dispose();

错误讯息：

  

必须指定收件人。

错误类型：

  

System.InvalidOperationException

服务器堆栈跟踪：

   at Microsoft.SharePoint.Client.ClientMethodsProcessor.ProcessStatements(XmlNode xe)
   at Microsoft.SharePoint.Client.ClientMethodsProcessor.Process()

这里有什么问题？

Answer 1

我认为必须将电子邮件收件人解析为当前的SharePoint网站用户。因此，您不能将随机电子邮件地址用作电子邮件收件人

Answer 2

尝试使用用户登录名而不是mailaddress;）

Answer 3

应该是：

user.LoginName after EnusreUser for Ex:
User user = clientContext.Web.EnsureUser(strlogonName);
clientContext.Load(user);
clientContext.ExecuteQuery();

EmailProperties properties = new EmailProperties();
properties.To = new string[] { user.LoginName };
properties.Subject = "Test subject";
properties.Body = "Test body";

ClientContext context = new ClientContext(webUrl);

Utility.SendEmail(context, properties);
