当我尝试向Web API发送数据时出现问题，这会导致异常 从调用COM组件返回了HRESULT E_FAIL
System.Net.Browser.ClientHttpWebRequest上的System.Net.Browser.ClientHttpWebRequest.InternalEndGetResponse（IAsyncResult asyncResult）.System.Net.Browser.AsyncHelper。<> c__DisplayClasse.b__d（Object sendState）。 sendState）
回应时 HttpResponseMessage response =等待client.GetAsync（String.Format（url，Isexist，jsontalleyHeader.ToString（），jsontalleydetail.ToString（）））;
Wp8方法
public async Task<string> POSTtalleyDetails(bool Isexist, int count)
{
string val = "";
if ((Isexist == false))//first time Load started--need headerNo
{
try
{
using (HttpClient client = new HttpClient())
{
var valjsontalleyHeader = listRtnTalleySheetHeader;
var jsontalleyHeader = Newtonsoft.Json.JsonConvert.SerializeObject(valjsontalleyHeader);
var valtalleydetail = listRtnTalleySheetDetail;
var jsontalleydetail = Newtonsoft.Json.JsonConvert.SerializeObject(valtalleydetail);
client.BaseAddress = new Uri("http://service:Port");
var url = "api/config/InsertTalleydetail?Isexist={0}&talleyheaderlist={1}&talleydetails={2}";
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
HttpResponseMessage response = await client.GetAsync(String.Format(url, Isexist, jsontalleyHeader.ToString(), jsontalleydetail.ToString()));
if (response.IsSuccessStatusCode)
{
val = "Ok";
}
else
{
val = "No";
}
}
return val;
}
catch (Exception ex)
{
ex.ToString(); return val = "No";
}
//
}
}
其中jsontalleydetail将为

和 jsontalleyHeader将

我的网络api方法是
[HttpPost]
public HttpResponseMessage InsertTalleydetail([FromBody]List<clsTalleySheetHeader> talleyheaderlist, List<clsTalleySheetDetail>talleydetails)
{
return todoService.InsertTalleydetail(talleyheaderlist, talleydetails);
//base.BuildSuccessResult(HttpStatusCode.OK, StartTimeDetails);
}
我相信这是因为由于数据负载，因为它可以使用2到3个jsontalleydetail正常工作。
如果有人可以就此建议我，那将是很大的帮助。
