Yahoo Finance API：远程服务器返回错误：（414）请求URI太长

我正在发送请求以资助雅虎，下面的代码工作正常，如果符号最大为200.如果符号超过200收到错误“远程服务器返回错误：（414）请求URI太长。”Yahoo Finance API：远程服务器返回错误：（414）请求URI太长

实际符号超过20000

你可以提出一个可能的解决方案？

string yahooQuoteUrl = "http://finance.yahoo.com/d/quotes.csv?s="; 
string yahooParameters = "&f=sl1d1yxn"; 
string Url =""; 
SqlConnection sqlConnection = new SqlConnection(con1); 
SqlCommand sqlCommand = new SqlCommand("SELECT Symbol FROM PM_Securities",sqlConnection); 
sqlConnection.Open(); 
SqlDataReader reader = sqlCommand.ExecuteReader(); 
GridView2.DataSource = reader; 
GridView2.DataBind(); 
string symbols= GridView2.Rows[0].Cells[0].Text; 

string csvData; 
    using (WebClient web = new WebClient()) 
    { 
     Url = yahooQuoteUrl + symbols+ yahooParameters; 
     csvData = web.DownloadString(Url); 
    } 


    List<Price> prices = Parse(csvData); 
    GridView1.DataSource = prices; 
    GridView1.DataBind();

将作业分成小于200多个单独的请求？ –

尝试使用POST而不是GET – rhughes

我只是更新我的代码。我的符号从我的数据库中检索，所以我不知道符号的确切数量。我的一个客户可能有10000或其他客户可能有30000或其他客户可能有100. – Leventis1984

我根据我已经数过的符号分开请求。下面的解决方案对我来说很好。

if (count <= 200) { 

     using (WebClient web = new WebClient()) 
     { 
      Url = yahooQuoteUrl + cellText200 + yahooParameters; 
      csvData200 = web.DownloadString(Url); 
     } 

     csvData = csvData200; 
     List<Price> prices = Parse(csvData); 
     GridView1.DataSource = prices; 
     GridView1.DataBind(); 

    } 


    if (count>=201 & count<=400) 
    { 

     using (WebClient web = new WebClient()) 
     { 
      Url = yahooQuoteUrl + cellText200 + yahooParameters; 
      csvData200 = web.DownloadString(Url); 
     } 

     using (WebClient web = new WebClient()) 
     { 
      Url = yahooQuoteUrl + cellText400 + yahooParameters; 
      csvData400 = web.DownloadString(Url); 
     } 

     csvData = csvData200 + csvData400; 
     List<Price> prices = Parse(csvData); 
     GridView1.DataSource = prices; 
     GridView1.DataBind(); 
    } 


    if (count >= 401 & count <= 600) 
    { 

     using (WebClient web = new WebClient()) 
     { 
      Url = yahooQuoteUrl + cellText200 + yahooParameters; 
      csvData200 = web.DownloadString(Url); 
     } 

     using (WebClient web = new WebClient())

      Url = yahooQuoteUrl + cellText400 + yahooParameters; 
      csvData400 = web.DownloadString(Url);

     using (WebClient web = new WebClient()) 
     { 
      Url = yahooQuoteUrl + cellText600 + yahooParameters; 
      csvData600 = web.DownloadString(Url); 
     } 

     csvData = csvData200 + csvData400 + csvData600; 
     List<Price> prices = Parse(csvData); 
     GridView1.DataSource = prices;
