百思不得其解的"Failed to allocate a managed memory buffer of 268435456 bytes."错误解决

最近要做一个上传功能的WCF,20M 70M都测试成后,但是在测试130M的时候,却跳出

"Failed to allocate a managed memory buffer of 268435456 bytes."

错误,

然后从MSDN的论坛里找到了一种方法,就是分段把文件内容传到服务器上,追加到文件结尾

 

                    byte[] buffer = new byte[65000];
                    int bytesRead = 0;

                    VODService.IVODService proxy = client.ChannelFactory.CreateChannel();

                    while ((bytesRead = fuUpload.PostedFile.InputStream.Read(buffer, 0, 65000)) > 0)
                    {
                        video.Data = buffer;
                        video.Offset = 0;
                        video.Count = bytesRead;
                        proxy.UploadVideo(video);
                    }

                    client.ChannelFactory.Close();

 

我想可能是一次传的文件放在内存里太大了

希望对大家有帮助
