Help uploading files via RestAPI C#

[BenBodie]

Hello,

I have read the help guide on https://sftpgo.stoplight.io/docs/sftpgo/4ac40206614d5-upload-files but i'm still struggling to get my code to work

I am getting 400 - bad request responses, saying no files have been uploaded

I am using the RestSharp nuget package to do this

var client = new RestClient(//OurURL);
var request = new RestRequest("api/v2/user/files", Method.Post);
request.AddHeader("Content-Type", "multipart/form-data");
request.AddHeader("Authorization", "Bearer " + accesstoken);
request.AddParameter("path", HttpUtility.UrlEncode(@"BB-Test"));
request.AddParameter("filenames", JsonConvert.SerializeObject(new List { @"C:\Uploadtest\Test1.txt", @"C:\Uploadtest\Test1 - Copy.txt" }), ParameterType.RequestBody);
RestResponse response = client.Execute(request);

Any help would be greatly appreciated
