如果这个问题很愚蠢，我很抱歉。但我坚持这个错误约2天。这让我很疯狂。这是我的问题

当我尝试调用webservices的webmethod（由.NET构建）时，会出现此问题。我在google和starkoverflow中寻找，并使用MarshalDate类尝试与实现KmvSerialize相同的解决方案但不适用于我。这是webmethod
[WebMethod]
public String searchingTickets(String date, String departure, String arrival)
{
List<Ticket_Information> listTicket = new List<Ticket_Information>();
String status;
DateTime datetime = new DateTime();
SqlConnection conn = new SqlConnection("workstation id=OrderingTicketsTS.mssql.somee.com;packet size=4096;user id=b5prolh_SQLLogin_1;pwd=dxtcq1cbar;data source=OrderingTicketsTS.mssql.somee.com;persist security info=False;initial catalog=OrderingTicketsTS");
SqlCommand cmd = new SqlCommand("select * from ticket_information where Date = '" + date + "' and Departure = '" + departure + "' and arrival = '" +arrival+ "'", conn);
conn.Open();
SqlDataReader dr = cmd.ExecuteReader();
if (dr.HasRows)
{
while (dr.Read())
{
Ticket_Information ticket_information = new Ticket_Information();
if (dr.GetBoolean(9) == true)
{
status = "Sold Out";
}
else
{
status = "Still";
}
ticket_information.ID_Ticket = dr.GetString(0);
ticket_information.Company = dr.GetString(1);
ticket_information.Departure = dr.GetString(2);
ticket_information.Arrival = dr.GetString(3);
ticket_information.Vehicles_type = dr.GetString(4);
ticket_information.Services = dr.GetString(5);
datetime = dr.GetDateTime(6);
ticket_information.Date = datetime.ToString("MM/dd/yyyy");
ticket_information.Time = dr.GetString(7);
ticket_information.Price = dr.GetDouble(8);
ticket_information.Ticket_Status = status;
listTicket.Add(ticket_information);
}
}
return listTicket.ParserJSon();
conn.Close();
}
SQL Server中的日期参数类型是Date。当我在本地运行webservices并测试时，它工作得很完美。之后，我通过Ksoap2在android中调用了这个方法，我的问题出现了。 这是我的SearchTicketActivity：
