我不认为这是有效的,我想知道你是否可以发现我的代码有什么问题,我可以解决它吗?我很新,并不确定是否使用Web请求,Web响应或任何东西。什么是对json进行POST的最基本方式?
谢谢
private void btnSaveCar_Click(object sender, RoutedEventArgs e)
{
string url = "http://......";
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
request.Method = "POST";
request.BeginGetRequestStream(new AsyncCallback(ProcessResponse), request);
}
private void ProcessResponse(IAsyncResult asyncResult)
{
HttpWebRequest request = (HttpWebRequest)asyncResult.AsyncState;
Stream streamResp = request.EndGetRequestStream(asyncResult);
DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(Car));
Car newCar = new Car():
Deployment.Current.Dispatcher.BeginInvoke(() =>
{
newCar.Condition = txtCondition.Text;
newCar.Colour = txtColour.Text;
newCar.RegistrationNumber = txtReg.Text;
newCar.Model = txtModel.Text;
short.TryParse(txtYear.Text, out newCar.Year);
short chassisNumber;
short.TryParse(txtChassisNumber.Text, out chassisNumber);
newCar.ChassisNumber = chassisNumber;
newCar.BodyStyle = txtBodyStyle.Text;
try
{
ser.WriteObject(streamResp, newCar);
NavigationService.GoBack();
}
catch
{
MessageBox.Show("didnt work :(");
}
});
}

您的代码不完整,您应该在将数据写入请求流后调用Request.BeginGetResponse()方法!
关于如何使用WebRequest进行POST,请查看this sample code(请注意该示例适用于.NET 4.0但我认为您会明白这一点。)
我仍然建议您使用RestSharp而不是使用基本的WebRequest来节省一些开发时间!
