Question

我收到了两个指向下面脚本的错误：

收到错误：

无法隐式转换类型'string' System.Collections.Generic.IEnumerable<Xrm.ActivityParty> FOR To = emailData.To，

还收到错误：

无法使用集合初始化类型'Xrm.ActivityParty' 初始化程序因为它没有实现 'System.Collections.IEnumerable'FOR From = new ActivityParty {

以下是代码：

foreach (var file in unReadFiles)
{
    Microsoft.Office.Interop.Outlook._MailItem emailData = oApp.Session.OpenSharedItem(file);

    try
    {
        Email scrapedMessage = new Email
        {
            Subject = emailData.Subject,
            Subcategory = EmailHelper.ScrapeMethod.Manual.ToString(),
            Description = emailData.HTMLBody,
            To = emailData.To,
            From = new ActivityParty{ 
                    emailData.Sender.Address
            }
        };
    }
}

Answer 1

似乎To是IEnumerab<ActivityParty>，您正试图为其分配一个简单的字符串。你可以使用这样的数组：

To = new [] {new ActivityParty { To= emailData.To }}

同样对于From属性，您需要声明属性名称：

From = new ActivityParty
{ 
    Address = emailData.Sender.Address
}

Answer 2

根据MSDN文档，您需要创建活动方类变量以指定“收件人”和“发件人”属性。

 private Guid _contactId;
    private Guid _userId;
// Create the 'From:' activity party for the email
                ActivityParty fromParty = new ActivityParty
                {
                    PartyId = new EntityReference(SystemUser.EntityLogicalName, _userId)
                };

                // Create the 'To:' activity party for the email
                ActivityParty toParty = new ActivityParty
                {
                    PartyId = new EntityReference(Contact.EntityLogicalName, _contactId)
                };
 To = new ActivityParty[] { toParty },
 From = new ActivityParty[] { fromParty },

无法将类型'string'隐式转换为'System.Collections.Generic.IEnumerable <xrm.activityparty>'
