构建 MultipartFormData API 响应
我需要构建一个 API，以字节数组形式返回 JSON 对象和附加文件。为此，我想到在 C# 中使用 MultipartFormDataContent 类。我的API是这样写的。
public async Task<IHttpActionResult> MethodName(Params){
......statements......
var responseContent = new MultipartFormDataContent();
......statements......
responseContent.Add(new StringContent(jsonString), 'JSON Object');
......statements......
responseContent.Add(byteArrayContent);
return responseContent;
}
这会在构建项目时出现错误，无法将responseContent 转换为IHttpActionResult。所以我尝试像这样显式转换。
return (IHttpActionResult)responseContent;
但这会引发无法转换为 IHttpActionResult 的运行时错误。那么我将如何返回responseContent。任何帮助表示赞赏。

responseContent.Add(byteArrayContent);
return responseContent;
}
This is giving an error while building the project about not being able to convert the responseContent to IHttpActionResult. So I tried explicit casting like so.
return (IHttpActionResult)responseContent;
But this throws a runtime error about not being able to convert to IHttpActionResult. So how would I go about returning responseContent. Any help is appreciated.
