I use te POSTMAN application to upload a file to an API,
now I want to actually do a POST commando in c#, how can I do this in the most efficient way?

url "192.168.0.1/api/files"

Header
key= Authorization, value = "123456"

Formdata
key= files, value = <file>
key= Info, value = <{"DocName": "Test"}>

if status == 200
Console.WriteLine("OK");
else
Console.WriteLine( "ERROR" + response.StatusCode + " : Message - " + response.ReasonPhrase);

What I have tried:

HttpClient client = new HttpClient();
client.BaseAddress = new Uri("https:///api.ontriz.com/files");
client.DefaultRequestHeaders.TryAddWithoutValidation("Authorization", "123456");

but then??

Use the MultipartFormDataContent class[^]:

C#

using (var form = new MultipartFormDataContent())
using (var stream = File.OpenRead(@"Path\To\Your\File.ext"))
using (var streamContent = new StreamContent(stream))
{
    form.Add(streamContent, "files");
    form.Add(new StringContent("<{\"DocName\": \"Test\"}>"), "Info");
    response = await client.PostAsync(null, form);
}
