Question

我正在尝试在电子邮件正文中显示取件号列表。我可以使用以下代码获得优惠号码：

foreach (LoadRelationship relationship in View.SelectedObjects)
{
///This works fine, I get 3 pickup numbers for my selected records///
    List<string> pickUpNumbers = View.SelectedObjects.Cast<LoadRelationship>()
    .Where(x => x != null && x.PurchaseLoad.PickupNumber != null)
    .Select(x => x.PurchaseLoad.PickupNumber)
    .ToList();
//When assigning the pickUpNumbers.To String to the body of the email it fails here:
e.Report.ExportOptions.Email.Body =  pickUpNumbers.ToString();
}

电子邮件正文中的输出是：

System.Collections.Generic.List`1 [System.String]

输出应该是这样的：

12345 2334556 12334445

Answer 1

试试这个：

e.Report.ExportOptions.Email.Body = string.Join(" ", pickUpNumbers);

Answer 2

尝试：

foreach (LoadRelationship relationship in View.SelectedObjects)
{
///This works fine, I get 3 pickup numbers for my selected records///
    List<string> pickUpNumbers = View.SelectedObjects.Cast<LoadRelationship>()
    .Where(x => x != null && x.PurchaseLoad.PickupNumber != null)
    .Select(x => x.PurchaseLoad.PickupNumber)
    .ToList();
//When assigning the pickUpNumbers.To String to the body of the email it fails here:

string body = "";
for(int i = 0; i < pickUpNumbers.Count; i++) {
   if (i > 0) {
       body += ", ";
   }
   body += puckUpNumbers[i];
}
e.Report.ExportOptions.Email.Body =  body;


}

Answer 3

输出为System.Collections.Generic.List1[System.String]，因为您有一组字符串并且直接在集合上调用.ToString()。

您可以通过遍历集合并构建电子邮件正文来获得所需的结果。

例如：

 StringBuilder sb = new StringBuilder();
 foreach(var pickupNumber in pickUpNumbers) {
     sb.Append(pickupNumber);
 }

 e.Report.ExportOptions.Email.Body = sb.ToString();

您也可以使用String.Join。

 e.Report.ExportOptions.Email.Body = string.Join(" ", pickUpNumbers);

将列表视图中的值列表显示到电子邮件正文中
