\ r \ n出現在字符串上？爲什麼 r n添加到我的字符串中？
試圖使用Rendering ASP.NET MVC Views to String上的示例將VIEW作爲字符串傳遞並作爲電子郵件發送。應該通過電子郵件將銷售發票發送給用戶。
Iv'e將ViewRenderer類添加到我的項目中。然後加入ContactSeller功能，我的控制器，並複製和重命名發票視圖ViewOrderThroughEmail.cshtml
//confirm payment & send invoice as email:
SendOrderInvoiceAsEmail(Qbcust, orderId);
private void SendOrderInvoiceAsEmail(QBCustomerRecord QBcust, int orderId)
{
string email = QBcust.EmailAddress;
if (String.IsNullOrWhiteSpace(email))
{
_orchardServices.Notifier.Error(T("No E-mail exists for this user. Invoice not sent."));
return;
}
var siteUrl = "Confirmation of order";
if (_authenticationService.GetAuthenticatedUser() == null)
throw new OrchardSecurityException(T("Login Required"));
IUser userInfo = _authenticationService.GetAuthenticatedUser();
QBCustomerRecord customer = _qbcustomerService.GetById(QBcust.Id);
IEnumerable<OrderRecord> ordersQuery = _orderService.GetOrders(customer.Id);
OrderRecord order = ordersQuery.Where(o => o.Id == orderId).FirstOrDefault();
var ids = order.Details.Select(d => d.ProductId);
ConvertOrderViewToStringViewModel model = new ConvertOrderViewToStringViewModel { Order = _orderService.GetOrder(orderId), Products = ProductHelper.GetProductLookup(ids, _qbProductService, true) };
model.Order = _orderService.GetOrder(orderId);
OrderSignatureRecord signatureRecord = _signatureService.GetByOrderId(orderId);
if (signatureRecord != null)
{
model.PathToSignature = _mediaService.GetPublicUrl(signatureRecord.PathToImageFile);
model.TypedName = signatureRecord.TypedName;
}
model.Payment = _paymentService.GetPaymentByOrderId(orderId);
string orderInvoiceEmailAsString = ConvertViewToString(model);
_userService.SendEmail(email, siteUrl, orderInvoiceEmailAsString);
_orchardServices.Notifier.Information(T("The user will receive a confirmation of their order through email."));
}
public string ConvertViewToString(ConvertOrderViewToStringViewModel model)
{
string message = ViewRenderer.RenderView("~/Modules/StormTree/Views/Account/ViewOrderThroughEmail.cshtml",model, ControllerContext);
return message;
}
我通過發送電子郵件的功能消失了，我從測試它知道發送電子郵件是不問題。電子郵件包含的是問題。
public bool SendEmail(string usernameOrEmail, string title, string viewAsString)
{
var lowerName = usernameOrEmail.ToLowerInvariant();
var user = _contentManager.Query<UserPart, UserPartRecord>().Where(u => u.NormalizedUserName == lowerName || u.Email == lowerName).List().FirstOrDefault();
if (user != null)
{
string nonce = CreateNonce(user, DelayToResetPassword);
//string url = createUrl(nonce);
string url = title;
_messageManager.Send(user.ContentItem.Record, MessageTypes.LostPassword, "email", new Dictionary<string, string> { { "LostPasswordUrl", url } });
return true;
}
return false;
}
所以我breakpointed並檢查了 'viewAsString' 參數傳入：回報：

我的問題是在哪裏都是\ r \ n從哪裏來？ 感謝您的任何答覆
UPDATE
public class ConvertOrderViewToStringViewModel
{
public ConvertOrderViewToStringViewModel()
{ }
public OrderRecord Order;
public Dictionary<int, QBProductRecord> Products;
public String PathToSignature;
public String TypedName;
public PaymentRecord Payment;
}
它看起來像所有東西都越獄了，注意'Order Last Last'中的\「以及'title'參數結果。通過調試代碼 – nrathaus
嘗試查看轉義的發生位置您確定已經檢查過'title'參數＆not'viewAsString'？因爲'title'參數被傳遞'siteUrl'＆'siteUrl'僅用「確認訂單」進行初始化，在此之後它不會被更改，至少這是我所能看到的從你的可用代碼中，我認爲問題在'viewAsString' –
這些是新的行字符，你使用輸入鍵或新行來縮進報表嗎？你可以發佈ConvertOrderViewToStringViewModel構造函數的代碼嗎？ –
