如何在swashbuckle中上传来自请求体的分块文件？

[HttpPost]
public IHttpActionResult UploadFile([FromBody]HttpPostedFileBase file)
{
    // 处理文件上传逻辑
    return Ok();
}

public class FileUploadOperationFilter : IOperationFilter
{
    public void Apply(Operation operation, SchemaRegistry schemaRegistry, ApiDescription apiDescription)
    {
        if (operation.operationId.ToLower() == "uploadfile")
        {
            operation.consumes.Add("multipart/form-data");
            operation.parameters = new List<Parameter>
            {
                new Parameter
                {
                    name = "file",
                    @in = "formData",
                    description = "The file to upload",
                    required = true,
                    type = "file"
                }
            };
        }
    }
}

config.EnableSwagger(c =>
{
    // 其他配置项...

    c.OperationFilter<FileUploadOperationFilter>();
})
.EnableSwaggerUi();
