.net core下载文件中文报错：Invalid non-ASCII or control character in header:

.net core下载附件遇到中文下载会报错：InvalidOperationException: Invalid non-ASCII or control character in header: 0x7528。

使用url编码一下就可以解决了

WebUtility.UrlEncode("用户信息表.xls")

整体代码如下：

//把内存流做为文件下载中转
MemoryStream memoryStream = new MemoryStream();
workbook.Write(memoryStream);
//Response.ContentEncoding = System.Text.Encoding.GetEncoding("UTF-8");
Response.ContentType = "application/octet-stream;charset=UTF-8"; ;
string newName = Guid.NewGuid().ToString().Replace("-", "");
Response.Headers.Add("Content-Disposition", "attachment;filename=" + WebUtility.UrlEncode("用户信息表.xls"));
//Response.Headers.Add("Content-Disposition", "attachment;filename=用户信息表.xls");
Response.BodyWriter.WriteAsync(memoryStream.ToArray());
Response.BodyWriter.FlushAsync();
