如何在 Post-C# 中使用 RestClient 传递 Xml 文件？

Question

I'm trying to pass xml file to api using RestSharp, but I'm receiving the file at the Post method as null.

Here is my code:

 public void SendXmlToApi()
    {
        var client = new RestClient(_uri);
        var request = new RestRequest(Method.POST);
        request.AddFile("Xml",XmlPath);
        request.RequestFormat = DataFormat.Xml;
        request.AddHeader("content-type", "application/xml");
        var response = client.Execute(request);
        bool res = (response.StatusCode == HttpStatusCode.OK);
    }

And my Post Func:

   [HttpPost]
    [Route("Test")]
    public void UpdateResult(XDocument a)
    {

        
    }

Any idea whats the problem?

I don't use XML, so this deviates a little from your example, but it is a viable option for posting XML into a [HttpPost] API endpoint. I used your SendXmlToApi() example untouched (just supplied my own _uri and XmpPath variables) and was successful (Core 3.1).

I modified your receiving code to be:

[HttpPost]
[Route("test")]
public async Task UpdateResult()
{
    string body = await new StreamReader(HttpContext.Request.Body).ReadToEndAsync();
    XDocument xdoc = XDocument.Parse(body);
}

Of course, you'll want to put guard rails on this and have proper error handling and validation, but it should get you over the hump.
