Do not call response.CompleteAsync() after write data to response.Body.When calling Close() on instances of StreamWriter and GZipStream, the underlying stream will be closed, NO MATTER the value of leaveOpen specified.WARNING: DO NOT CALL CompleteAsync, which will thrown an exception. Var uncompressed = (text) įinally, I get it work by this code below: public static async Task WriteWithGZipAndCompleteAsync(this HttpResponse response, string text)

Using (var gzip = new GZipStream(compressed, CompressionLevel.Optimal, true)) Using (var compressed = new MemoryStream()) The second version is worse, it sends nothing at all: //This code is not working either. It does send the text to the client but the gunzip reports “unexpected end of file” after decompressed all texts. Response.ContentType = 'application/gzip' Īwait using var gzip = new GZipStream(response.Body, CompressionLevel.Optimal, true) Īwait using var streamWriter = new StreamWriter(gzip, Encoding.UTF8, -1, true) Public static async Task WriteWithGZipAndCompleteAsync(this HttpResponse response, string text) Here is my first guess code, which is not working: //This code is not working. My request is easy: using GZipStream to compress a large text before sending it as response of asp.net content. Recently, I’m struggle with asp.net core 5 working with GZipStream.
