我使用从我的REST服务下载的文件的样本方法：

A sample method i use to download the file from my REST service:

[WebGet(UriTemplate = "file/{id}")] public Stream GetPdfFile(string id) { WebOperationContext.Current.OutgoingResponse.ContentType = "application/txt"; FileStream f = new FileStream("C:\\Test.txt", FileMode.Open); int length = (int)f.Length; WebOperationContext.Current.OutgoingResponse.ContentLength = length; byte[] buffer = new byte[length]; int sum = 0; int count; while((count = f.Read(buffer, sum , length - sum)) > 0 ) { sum += count; } f.Close(); return new MemoryStream(buffer); }
