Client Query String empty IEnumerable error #5194
Description
Query string is invalid
Previous versions of NSwag have generated valid query string parameters where the IEnumerable contains no elements.
Version 14.4.0 .NET 8
Previous working Version 14.2.0
To Reproduce
With version 14.2.0
if (orderStatus != null)
{
foreach (var item_ in orderStatus)
{
urlBuilder_.Append(System.Uri.EscapeDataString("orderStatus")).Append('=').Append(System.Uri.EscapeDataString(ConvertToString(item_, System.Globalization.CultureInfo.InvariantCulture))).Append('&');
}
}With version 14.4.0
if (orderStatus != null)
{
urlBuilder_.Append(Uri.EscapeDataString("orderStatus") + "=");
foreach (var item_ in orderStatus)
{
urlBuilder_.Append(Uri.EscapeDataString(ConvertToString(item_, System.Globalization.CultureInfo.InvariantCulture))).Append(",");
}
urlBuilder_.Length--;
urlBuilder_.Append("&");
}Expected behavior
Should get …queryProductOrder?destinationFolderId=FN-0000000816&offset=0&limit=90
With no order status parameter
Whereas 14.4.0 generates this
…queryProductOrder?destinationFolderId=FN-0000000816&orderStatus&offset=0&limit=90
