我正在製作WCF服務來傳輸文件。我只有基本的WCF理解,並遵循MSDN教程:WCF Tutorial 我開始使用字節數組來傳輸文件,但只要文件有一點點大(100kb就足夠了),它會因錯誤的請求而失敗。 我遵循另一個指南,並改爲使用消息流式傳輸,它也適用於小文件,但與較舊的版本一樣會失敗。我懷疑這個錯誤在我的配置文件中,因爲svcutil.exe生成的配置文件沒有提供關於流式處理的任何信息。 這是我的客戶的app.config:WCF Streaming無法傳輸大文件

我無法在服務器上設置bufferSize,只是maxBufferSize。我嘗試了你所建議的改變,但他們沒有奏效。我已經用新值更新了我的代碼。 – 2013-03-14 15:23:23
