I'm trying to use an Autorest generated C# client to send MultipartFormDataContent but the request always fails as it seems that the RequestContent in Azure.Core does not seem to support naïve usage.

我正试图使用Autorest生成的C#客户端发送MultipartFormDataContent，但请求总是失败，因为Azure中的RequestContent似乎不支持天真的使用。

For example, I'd like to do something like this:

例如，我想做这样的事情：

RequestContext myRequestContext = new RequestContext();
MultipartFormDataContent formData = myObject.ToMultipartFormDataContent();
RequestContent content = RequestContent.Create(formData);
myAutorestClient.MyEndpointPost(content, myRequestContext);

However, it seems as if the RequestContent.Create call fails to properly convert the MultipartFormDataContent.

然而，RequestContent.Create调用似乎未能正确转换MultipartFormDataContent。

Is there any guidance on how to properly send Multipart form data using the Azure.Core RequestContent object?

关于如何使用Azure.Core RequestContent对象正确发送多部分表单数据，是否有任何指导？

Try to use ConvertMultipartFormDataContent method to implement it.

尝试使用ConvertMultipartFormDataContent方法来实现它。

private async Task<RequestContent> ConvertMultipartFormDataContent(MultipartFormDataContent formDataContent)
{
    using (MemoryStream ms = new MemoryStream())
    {
        await formDataContent.CopyToAsync(ms);
        byte[] formDataAsBytes = ms.ToArray();
        return RequestContent.Create(formDataAsBytes);
    }
}

The usage should be like below:

用法应如下所示：

public async Task<Response> Test(MyObject myObject, RequestContext myRequestContext)
{
    RequestContext myRequestContext = new RequestContext();
    MultipartFormDataContent formData = myObject.ToMultipartFormDataContent();
    RequestContent content = await ConvertMultipartFormDataContent(formData);
    return await myAutorestClient.MyEndpointPost(content, myRequestContext);
}
