我必須制作一個(gè)使用照片返回年齡的程序，我正在使用 Azure 的faceApi 服務(wù)。它返回下面的代碼[? ?{? ? ? "faceId": "f7eda569-4603-44b4-8add-cd73c6dec644",? ? ? "faceRectangle": {? ? ? ? ?"top": 131,? ? ? ? ?"left": 177,? ? ? ? ?"width": 162,? ? ? ? ?"height": 162? ? ? },? ? ? "faceAttributes": {? ? ? ? ?"smile": 0.0,? ? ? ? ?"headPose": {? ? ? ? ? ?

"foreheadOccluded": false,? ? ? ? ? ? "eyeOccluded": false,? ? ? ? ? ? "mouthOccluded": false? ? ? ? ?},我更改了代碼以減少它，因?yàn)槲抑恍枰挲g?，F(xiàn)在輸出是這樣的[{"faceId":"b2342836-6d99-4f69-b656-1a64b786b421","faceRectangle":{"top":60,"left":52,"width":58,"height":58},"faceAttributes":{"age":40.0}}]?我認(rèn)為一切都是正確的，但是每當(dāng)我嘗試反序列化時(shí)都會(huì)返回一個(gè)對(duì)象 null。例如我嘗試過使用這個(gè)Analysis?dsjson?=?new?JavaScriptSerializer().Deserialize<Analysis>(contentString);有人可以幫我解決這個(gè)問題嗎？提前致謝。
