why is the difference between the code generated in postman and by httpsnippet?

I was trying to use httpSnippet to generate client-code in C# and I got
```
var client = new RestClient("https://api.apyhub.com/extract/text/word-file");
var request = new RestRequest(Method.POST);
request.AddHeader("apy-token", "APY0kllzrWDJ1AXxg3cfjxwfAhrXaSuarykmVh2gqleNPi0LujGn4vflrsu1MC58");
request.AddHeader("Content-Type", "multipart/form-data; boundary=---011000010111000001101001");
request.AddParameter("multipart/form-data; boundary=---011000010111000001101001", "-----011000010111000001101001\r\nContent-Disposition: form-data; name=\"file\"\r\n\r\n@\"test.docx\"\r\n-----011000010111000001101001--\r\n", ParameterType.RequestBody);
IRestResponse response = client.Execute(request);
```

which is differed from I got in postman
```
var options = new RestClientOptions("https://api.apyhub.com")
{
MaxTimeout = -1,
};
var client = new RestClient(options);
var request = new RestRequest("/extract/text/word-file", Method.Post);
request.AddHeader("apy-token", "APY0kllzrWDJ1AXxg3cfjxwfAhrXaSuarykmVh2gqleNPi0LujGn4vflrsu1MC58");
request.AlwaysMultipartFormData = true;
request.AddFile("file", "/path/to/file");
RestResponse response = await client.ExecuteAsync(request);
Console.WriteLine(response.Content);
```

are they same ?
why is the differnece ?

Start by comparing the C# output from httpsnippet with the C# code generated by Postman for the multipart request shown in the issue. Check whether both snippets send the same file field and request body, then determine whether the discrepancy is an expected library-version difference or a generator bug; done means documenting or correcting the mismatch.
