我在我的chrome中使用以下URL,它运行正常:https: //westus.api.cognitive.microsoft.com/luis/v2.0/apps/62bea90c-9b0c-487b-8416-1a4d94772f99?subscription-key=29317e2237fb4b43a91959cadee6f143&staging=真冗长=真&的timezoneoffset = 480&q =哪个国家获得2010年世界杯第一名

它返回json字符串,如下所示:

{
  "query": "??????2010???????",
  "topScoringIntent": {
    "intent": "Query",
    "score": 0.9818858
  },
  "intents": [
    {
      "intent": "Query",
      "score": 0.9818858
    },
    {
      "intent": "None",
      "score": 0.01755463
    }
  ],
  "entities": [
    {
      "entity": "2010?",
      "type": "builtin.datetimeV2.daterange",
      "startIndex": 6,
      "endIndex": 10,
      "resolution": {
        "values": [
          {
            "timex": "2010",
            "type": "daterange",
            "start": "2010-01-01",
            "end": "2011-01-01"
          }
        ]
      }
    },
    {
      "entity": "2010",
      "type": "builtin.number",
      "startIndex": 6,
      "endIndex": 9,
      "resolution": {
        "value": "2010"
      }
    },
    {
      "entity": "?",
      "type": …

如何使用.NET(VB或C#)轻松地将字符串编码为utf8？例如,我需要编码一个像"This(is)my string"这样的字符串,结果应该是一个字符串"This +%28is%29 + my + string".

TIA
