c# - 将 ListView 中的值列表显示到电子邮件正文中

Question

我正在尝试在电子邮件正文中显示取件号码列表。我可以使用以下代码获得取货号码:

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如下:

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

输出应该是这样的:

12345233455612334445

Answer 1

试试这个:

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