我想从浏览器上点击按钮下载文件。当我点击按钮时，什么也没有发生。我暂时存储在本地文件夹中的文件只是为了检查文件，我可以看到文件被存储。

API

[HttpGet]
    [Route("[controller]/downlaodCSV/{pID}/{customerID}")]
    public System.Net.Http.HttpResponseMessage downlaodCSV(int pID, int customerID)
    {
        //getting the file
        var rateFilename = _Client.RateRepository.downlaodCSV(pID, customerID);
        
            var stream = new System.IO.MemoryStream();
            processing the stream.

            var result = new System.Net.Http.HttpResponseMessage(System.Net.HttpStatusCode.OK)
            {
                Content = new System.Net.Http.ByteArrayContent(stream.ToArray())
            };
            result.Content.Headers.ContentDisposition =
                new System.Net.Http.Headers.ContentDispositionHeaderValue("attachment")
                {
                    FileName = rateFilename
                };
            result.Content.Headers.ContentType = new System.Net.Http.Headers.MediaTypeHeaderValue("application/octet-stream");

            return result;
    }

费率存储库：这是我的商业逻辑

public string downlaodCSV(int pID, int customerID)
    {
        Random _random = new Random();
        int number = _random.Next(1, 9999);

        string fileName = "";
        try
        {   
            #region Dummy Data            
            //Dummy Data for now -- this will be changed by correct data from the API
            DataTable rates = new DataTable();
            rates.Clear();
            rates.Columns.Add("Name");
            rates.Columns.Add("Surname");

            DataRow dr = rates.NewRow();
            dr["Name"] = "Test1";
            dr["Surname"] = "Test2";
            rates.Rows.Add(dr);

            #endregion

            if (rates.Rows.Count > 0)
            {
                StringBuilder stringBuilder = new StringBuilder();
                string[] columnNames = rates.Columns.Cast<DataColumn>(). Select(column => column.ColumnName).ToArray();
                stringBuilder.AppendLine(string.Join(",", columnNames));

                foreach (DataRow row in rates.Rows)
                {
                    string[] fields = row.ItemArray.Select(field => field.ToString()).ToArray();
                    stringBuilder.AppendLine(string.Join(",", fields));
                }

                fileName = CsvFilename(number);

                //Save to file to check the file. this will be deleted.
                string html = String.Empty;
                var newName = fileName;
                var path = @"C:\test\ " + newName + "";
                File.WriteAllText(fileName, stringBuilder.ToString());
                File.SetAttributes(fileName, FileAttributes.Normal);

                File.WriteAllText(path, html);
            }
            else
            {
                throw new Exception("Rates data to download not found!");
            }
        }
        catch (Exception ex)
        {
            throw ex;
        }
       return fileName;
    }
