Question

我们正在升级到ConvertAPI指定的新逻辑。但是我们使用的框架是4，因为没有找到using System.Net; using System.IO; string url = "GET https://api.companieshouse.gov.uk/search/companies"; HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url); request.Credentials = // here you have to set your authentication data HttpWebResponse response = (HttpWebResponse)request.GetResponse(); Stream resStream = response.GetResponseStream();，System.Net.Http(HttpResponseMessage，HttpClient，MultipartFormDataContent，StreamContent）类。甚至添加了StringContent引用。但仍然存在同样的错误。有人可以建议一些解决方法吗？如何在C＃中使用ConvertApi for .Net Framework 4？

只需使用WebClient代替HttpClient即可快速上传文件。要运行下面的演示，您需要替换文件路径并在端点URL中设置您的秘密而不是 xxxxx 。此外，我们应该设置accept:application/octet-stream标头以将响应作为数据流而不是json。

class Program
    {
        static void Main(string[] args)
        {            
            const string fileToConvert = @"C:\Projects\_temp\test1.docx";
            const string fileToSave = @"C:\Projects\_temp\test1.pdf";            

            try
            {
                using (var client = new WebClient())
                {
                    client.Headers.Add("accept", "application/octet-stream");
                    var resultFile = client.UploadFile(new Uri("https://v2.convertapi.com/docx/to/pdf?Secret=xxxxx"), fileToConvert); 
                    File.WriteAllBytes(fileToSave, resultFile );
                    Console.WriteLine("File converted successfully");
                }
            }
            catch (WebException e)
            {
                Console.WriteLine("Status Code : {0}", ((HttpWebResponse)e.Response).StatusCode);
                Console.WriteLine("Status Description : {0}", ((HttpWebResponse)e.Response).StatusDescription);
                Console.WriteLine("Body : {0}", new StreamReader(e.Response.GetResponseStream()).ReadToEnd());
            }

            Console.ReadLine();
        }
    }
