我有一个Windows服务，该主体中的代码是一个经过时间的计时器方法。
我在循环中调用一些Web服务，这些Web服务在一个线程中运行。
我检查了服务器上的服务，他们没有启动。
当我从线体中取出代码时，那些工作。
这是我的Windows服务代码，它从服务器调用webservices。
private void CallServiceForTrancoding(object sender, System.Timers.ElapsedEventArgs e)
{
DataSet.TranscodingVideosDataTable oTranscodingVideosDataTable = new DataSet.TranscodingVideosDataTable();
DataSetTableAdapters.TranscodingVideoTableAdapter oTranscodingVideoTableAdapter = new DataSetTableAdapters.TranscodingVideoTableAdapter();
oTranscodingVideoTableAdapter.FillVideosForTranscoding(oTranscodingVideosDataTable);
DataSet.ServersDataTable oServersDataTable = new DataSet.ServersDataTable();
DataSetTableAdapters.ServersTableAdapter oServersTableAdapter = new DataSetTableAdapters.ServersTableAdapter();
oServersTableAdapter.FillBaseOnConvertAction(oServersDataTable);
for (int i = 0; i < oTranscodingVideosDataTable.Count; i++)
{
if (oTranscodingVideosDataTable[i].IsQualityNull() == false)
{
var Qualities = oTranscodingVideosDataTable[i].Quality.Split(new string[] { "," }, StringSplitOptions.RemoveEmptyEntries);
string path = oTranscodingVideosDataTable[i].Path + oTranscodingVideosDataTable[i].ObjectUniqueName;
string[] Url = new string[Qualities.Length];
for (int j = 0; j < Qualities.Length; j++)
{
if (j == 0)
{
Url[j] = path;
}
else
{
Url[j] = path.Replace(path.Split('/').Last(), "") + path.Split('/').Last().Split('.')[0] + "-" + Qualities[j] + "." + path.Split('/').Last().Split('.')[1];
}
}
string parameters = "Token=" + "@HelloWorld" +
"&Url=" + new JavaScriptSerializer().Serialize(Url) +
"&FileUniqueName=" + oTranscodingVideosDataTable[i].ObjectUniqueName +
"&ip=" + oTranscodingVideosDataTable[i].IPValid +
"&GregoreanDate=" + oTranscodingVideosDataTable[i].Gorean_Date.ToString();
DataSet.VideoDataTable oVideoDataTable = new DataSet.VideoDataTable();
DataSetTableAdapters.VideoTableAdapter oVideoTableAdapter = new DataSetTableAdapters.VideoTableAdapter();
oVideoTableAdapter.UpdateVideoStatus(oTranscodingVideosDataTable[i].ObjectUniqueName);
string WebServiceOfServer = oServersDataTable[i].WebService;
WebServiceOfServer = WebServiceOfServer.Replace(WebServiceOfServer.Split('/').Last(), "RS");
JavaScriptSerializer objSerializer = new JavaScriptSerializer();
//Task a = Task.Factory.StartNew(() => {
Task ResponseResult = GetPostMethods.POST(WebServiceOfServer, parameters);
string JSONResult = new System.Web.Script.Serialization.JavaScriptSerializer().Serialize(ResponseResult);
var ResponseString = objSerializer.Deserialize<dynamic>(JSONResult);
var UserToken = ResponseString["Result"]["UserToken"];
var Successfully = ResponseString["Result"]["Successfully"];
//});
}
}
}
这是我的网络方法：

Task ResponseResult = GetPostMethods.POST(WebServiceOfServer, parameters);
string JSONResult = new System.Web.Script.Serialization.JavaScriptSerializer().Serialize(ResponseResult);
您正在序列化任务。你肯定想等待结果，不是吗？

我调试了我的Web服务，发现问题与线程中的httpcontext.current有关。
为此，我将HttpContext.Current.Server.MapPath("/video/")定义为类中的变量，我从Web服务中调用它。
