我试图找出为什么tweetinvi流媒体库因为从关注者那里得到过多推文而陷入困境，我添加了函数AddFollow()。在这个函数中，我使用我创建的列表来放置600个关注者。我在应用程序上收到的这些推文中的每一条都直接发送到数据库，但在不确定的时间，应用程序只是停止发送推文，并且在调试模式下它不会显示任何错误或异常。它在C＃中的程序和我使用visual studio 2012
这是我的代码：
public void getTweets()
{
string[] sports = new string[] { "NFL" };
long[] list1 = critter_connex(sports);
int cont = 0;
DateTime pastDate = DateTime.MinValue;
string tweetType = "";
int id = 0;
using (var webClient = new WebClient())
{
webClient.Proxy = WebRequest.DefaultWebProxy;
webClient.Credentials = System.Net.CredentialCache.DefaultCredentials; ;
webClient.Proxy.Credentials = System.Net.CredentialCache.DefaultCredentials;
webClient.Headers["User-Agent"] = "MOZILLA/5.0 (WINDOWS NT 6.1; WOW64) APPLEWEBKIT/537.1 (KHTML, LIKE GECKO) CHROME/21.0.1180.75 SAFARI/537.1";
//using app key NECESITO VER TWEETS3
var credentials = TwitterCredentials.CreateCredentials("XXXXX", "XXXXX", "XXXXX", "XXXXX");
try
{
TwitterCredentials.ExecuteOperationWithCredentials(credentials, () =>
{
cont++;
var filteredStream = Stream.CreateFilteredStream();
for (int i = 0; i < list1.Length; i++)
{
filteredStream.AddFollow(list1[i]);
}

您是否尝试过注册StreamStopped事件并检查一切是否正常工作？
filteredStream.StreamStopped += (sender, args) =>
{
Console.WriteLine(args.DisconnectMessage.Reason);
if (args.Exception != null)
{
Console.WriteLine(args.Exception);
}
};
