我正在从ASP.NET Web API重写一个POST方法到ASP.NET Core我不知道如何重写下面的代码。此代码在ASP.NET Web API中工作正常。 ASP.NET Web Api：

I am re-writing a POST method from ASP.NET Web API to ASP.NET Core I am not sure how to re-write the below code. This code works fine in ASP.NET Web API. ASP.NET Web Api:

public IHttpActionResult Post() { var rawds = ConvertByteToArray(Request.Content.ReadAsStreamAsync().Result); //error here at Content //do something } private byte[] ConvertByteToArray(Stream stream) { using (MemoryStream ms = new MemoryStream()) { stream.CopyTo(ms); return ms.ToArray(); } }

我的尝试： 当我在ASP.NET Core中编写如下相同的代码时，我得到以下错误'HttpRequest'不包含'Content'的定义，也没有扩展方法'Content'接受a可以找到类型'HttpRequest'的第一个参数（你是否缺少using指令或程序集引用？） ASP.NET核心：

What I have tried: When I write the same code as below in ASP.NET Core I get the following error 'HttpRequest' does not contain a definition for 'Content' and no extension method 'Content' accepting a first argument of type 'HttpRequest' could be found (are you missing a using directive or an assembly reference?) ASP.NET Core:

public IActionResult Post() { var rawds = ConvertByteToArrayAsync(Request.Content.ReadAsStreamAsync().Result); //do something } public static async Task<byte[]> ConvertByteToArrayAsync(Stream stream) { using (var ms = new MemoryStream(2048)) { await request.Body.CopyToAsync(ms); //get error here at request return ms.ToArray(); } }

推荐答案

await request.Body.CopyToAsync(ms);

1.无论如何，它应该是Request（R而不是r）！ 2.似乎是一个逻辑错误，你将'Result'流传递给函数但不使用它？你可能想把它复制到ms？

1. In any case it should be Request (R and not r)! 2. It seems to be a logic error, that you pass the 'Result' stream to the function but do not use it? You probably meant to copy it to ms?
