期待中的WebAPI

Question

JSON/XML數據時，我要求一個的WebAPI請求，我有錯誤，如期待JSON/XML數據

try   
{     
    string oRequest = _xml.UpdateInvereqxml(UserName, Password,OTAhotelid, Invy);     
    string uri = @"service/update"; 
    System.Net.WebRequest req = System.Net.WebRequest.Create(uri); 
    req.Method = "POST"; 
    req.ContentType = "text/xml"; 
    System.IO.StreamWriter writer = new System.IO.StreamWriter(req.GetRequestStream()); 
    writer.WriteLine(oRequest); 
    writer.Close(); 
    System.Net.WebResponse rsp = req.GetResponse(); 
    Stream istrm = rsp.GetResponseStream(); 
    string StreamReader = new StreamReader(istrm).ReadToEnd(); 
}

我建議使用的HttpClient用的ASP.NET Web API進行通信。該類提供了許多使用REST服務的功能（example）

public EnumProduct Post(EnumProduct product) 
{ 
HttpResponseMessage reponse = httpClient.PostAsJsonAsync("api/enumproducts/Post", product).Result; 
if (reponse.IsSuccessStatusCode) 
{ 
var enumProduct = reponse.Content.ReadAsAsync().Result; 
return enumProduct; 
} 
else 
return null; 
}
