Post File With C#
Post 的資料好像會變大, 要改 Web.config
<system.web>
    <httpRuntime requestValidationMode="2.0" maxRequestLength="1024000"/>
</system.web>



程式碼如下:

public string UploadFilesToRemoteUrl(string url, string[] files, NameValueCollection formFields = null)
    {
        string boundary = "----------------------------" + DateTime.Now.Ticks.ToString("x");

        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
        request.ContentType = "multipart/form-data; boundary=" +
                                boundary;
        request.Method = "POST";
        request.KeepAlive = true;

        Stream memStream = new System.IO.MemoryStream();

        var boundarybytes = System.Text.Encoding.ASCII.GetBytes("\r\n--" +
                                                                boundary + "\r\n");
        var endBoundaryBytes = System.Text.Encoding.ASCII.GetBytes("\r\n--" +
                                                                    boundary + "--");


        string formdataTemplate = "\r\n--" + boundary +
                                    "\r\nContent-Disposition: form-data; name=\"{0}\";\r\n\r\n{1}";

        if (formFields != null)
        {
            foreach (string key in formFields.Keys)
            {
                string formitem = string.Format(formdataTemplate, key, formFields[key]);
                byte[] formitembytes = System.Text.Encoding.UTF8.GetBytes(formitem);
                memStream.Write(formitembytes, 0, formitembytes.Length);
            }
        }

        string headerTemplate =
            "Content-Disposition: form-data; name=\"{0}\"; filename=\"{1}\"\r\n" +
            "Content-Type: application/octet-stream\r\n\r\n";

        for (int i = 0; i < files.Length; i++)
        {
            memStream.Write(boundarybytes, 0, boundarybytes.Length);
            var header = string.Format(headerTemplate, "uplTheFile", files[i]);
            var headerbytes = System.Text.Encoding.UTF8.GetBytes(header);

            memStream.Write(headerbytes, 0, headerbytes.Length);

            using (var fileStream = new FileStream(files[i], FileMode.Open, FileAccess.Read))
            {
                var buffer = new byte[1024];
                var bytesRead = 0;
                while ((bytesRead = fileStream.Read(buffer, 0, buffer.Length)) != 0)
                {
                    Response.Write("bytesRead: " + bytesRead.ToString() + "<br>");
                    memStream.Write(buffer, 0, bytesRead);
                }
            }
        }

        memStream.Write(endBoundaryBytes, 0, endBoundaryBytes.Length);
        request.ContentLength = memStream.Length;

        using (Stream requestStream = request.GetRequestStream())
        {
            memStream.Position = 0;
            byte[] tempBuffer = new byte[memStream.Length];
            memStream.Read(tempBuffer, 0, tempBuffer.Length);
            memStream.Close();
            requestStream.Write(tempBuffer, 0, tempBuffer.Length);
        }

        try
        {
            using (var response = request.GetResponse())
            {
                Stream stream2 = response.GetResponseStream();
                StreamReader reader2 = new StreamReader(stream2);
                return reader2.ReadToEnd();
            }
        }
        catch (Exception ex)
        {
            return (ex.ToString());
            throw;
        }
    }
