hii, you have not specified that you want a get or post what is this then? var formContent = new MultipartFormDataContent { {new StringContent( "value1" ), "key1" }, {new StringContent( "value2" ), "key2" }, }; if you want to set content type then request.Content.Headers.Add( "ContentType" , "multipart/form-data); // request is httpClient obj

Where you mentioned content type Multi-Part/form data

Sachin Singh · Answer

it depends on what do you want to achieve? private static async Task Upload(string actionUrl) { var formContent = new MultipartFormDataContent { {new StringContent( "value1" ), "key1" }, {new StringContent( "value2" ), "key2" }, }; var myHttpClient = new HttpClient(); var response = await myHttpClient.PostAsync(actionUrl.ToString(), formContent); string stringContent = await response.Content.ReadAsStringAsync(); return response; } This is , how we send multipartForm data using http client.

Hi Market, Please try this code, public static async Task string > UploadFile( byte [] image) { using (var client = new HttpClient()) { using (var content = new MultipartFormDataContent( "Upload----" + DateTime.Now.ToString(CultureInfo.InvariantCulture))) { content.Add( new StreamContent( new MemoryStream(image)), "builddate" , "upload.jpg" ); using ( var message = await client.PostAsync( "http://www.Fileupload.net/index.php?mode=upload" , content)) { var input = await message.Content.ReadAsStringAsync(); return ! string .IsNullOrWhiteSpace(input) ? Regex.Match(input, @ "http://\w*\.Fileupload\.net/images/\d*/\w*\.[a-z]{3}" ).Value : null ; } } } }
