批量查詢到webservice返回「Uri字符串太長」

我想發送大的請求到服務器並獲取大數據。所以我使用批量請求到數據服務。此請求的URI如下所示：「hxxp：//company/Test.svc/$batch」。我使用.NET 4.0批量查詢到webservice返回「Uri字符串太長」

我發送有效的POST請求：

DataServiceRequest[] Request = new DataServiceRequest[]{new DataServiceRequest<TTable>((query).RequestUri)}; 
try 
{ 
    DataServiceResponse dsr = WebService.ExecuteBatch(Request); 
    foreach (QueryOperationResponse qr in dsr) 
    { 
     if (qr.Query.ElementType == typeof(TTable)) 
     { 
      foreach (TTable item in qr) { list.Add(item); } 
     } 
    } 
}

而且收到一條錯誤消息：

<?xml version="1.0" encoding="utf-8" standalone="yes"?> 
<error xmlns="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata"> 
    <code></code> 
    <message xml:lang="ru-RU">An error occurred while processing this request.</message> 
    <innererror> 
    <message>Invalid URI: The Uri string is too long.</message> 
    <type>System.UriFormatException</type> 
    <stacktrace> at System.Uri.CreateThis(String uri, Boolean dontEscape, UriKind uriKind)&#xD; 
    at System.Uri..ctor(String uriString, UriKind uriKind)&#xD; 
    at System.Data.Services.RequestUriProcessor.GetAbsoluteUriFromReference(String reference, Uri absoluteServiceUri)&#xD; 
    at System.Data.Services.BatchServiceHost..ctor(Uri absoluteServiceUri, BatchStream batchStream, String contentId, String boundary, StreamWriter writer)&#xD; 
    at System.Data.Services.DataService`1.BatchDataService.CreateOperationContextFromBatchStream(Uri absoluteServiceUri, BatchStream batchStream, HashSet`1 contentIds, String boundary, StreamWriter writer)&#xD; 
    at System.Data.Services.DataService`1.BatchDataService.HandleBatchContent(Stream responseStream)</stacktrace> 
    </innererror> 
</error>

這似乎是服務器端異常，occures當它嘗試解析大烏里。如何避免這種限制？
