Double quotes option for multipart/form-data boundary

I tried migration 104 to 108.

But since version 107, System.net.http is used for Http Request. It makes difference.

When upload file using multipart/form-data, AddFiles called.
And it makes MultipartFormDataContent and pass boundary to parameter.

RestSharp/src/RestSharp/Request/RequestContent.cs

Lines 48 to 51 in f7d3984

    
           void AddFiles() { 
        
               if (!_request.HasFiles() && !_request.AlwaysMultipartFormData) return; 
        
               var mpContent = new MultipartFormDataContent(GetOrSetFormBoundary());

Also this is :

RestSharp/src/RestSharp/Request/RequestContent.cs

Line 211 in f7d3984

? $"{contentType}; boundary=\"{GetOrSetFormBoundary()}\""

When MultipartFormDataContent created the boundary parameter will always wrapped "(double quotes).

boundary will like this in version 107 :

boundary="gc0pJq0M8jU534c0p"

But in version 104 :

boundary=gc0pJq0M8jU534c0p

There is no double quotes.
According to RFC 2046 double quotes is selective option.

How about add new option in RestSharp for double quotes?

The option already exists, but it wasn't applied in that case.

I am wrong, the option is to use quotes around parameter names, sorry.

I was able to fix it when the content type header is added manually to the request using AddHeader. But when the constructor of MultipartFormDataContent is called, RestSharp provides it with the boundary without quotes, and here what happens in .NET code:

            string quotedBoundary = boundary;
            if (!quotedBoundary.StartsWith('\"'))
            {
                quotedBoundary = "\"" + quotedBoundary + "\"";
            }

I made a change to re-create the content type header to work around this.
