C# 创建未连接到页面的链接广告：

我正在尝试实现此处描述的创建广告请求：

看起来这个错误是由creative参数引起的，但是我找不到如何正确地传递这个参数。

为什么您的参数与cURL示例的参数不匹配？因为确切的cURL示例报告了这些错误

curl \
  -F 'name=Sample Creative' \
  -F 'title=my title' \
  -F 'body=my body' \
  -F 'object_url=https://www.link.com' \
  -F 'link_url=https://www.link.com' \
  -F 'image_hash=<IMAGE_HASH>' \
  -F 'access_token=<ACCESS_TOKEN>' \
  https://graph.facebook.com/v2.11/act_<AD_ACCOUNT_ID>/adcreatives

var adParameters = new Dictionary<string, string>

    {
     {"adset_id", $"{adSetId}"},
     {"name", $"{adname}"},
     {"title", $"{title}"},
     {"image_hash", $"{imageHash}"},
     {"object_url", $"{objectUrl}"},
     {"link_url", $"{objectUrl}"},
     {"creative", "{\"creative_id\":6081438180357}"},
     {"status", "PAUSED"},
     {"access_token", _permanentAccessToken}
    };
