C# 反序列化JSON并从数据中获取特定行（用c表示）#

我试图得到一个特定的行，它是来自这个JSON API的元素

API的链接如下所示：

这就是它将返回的结果：

            "fee": 0.2
        }
    }
}

我想要的是只解析结尾带有“ltc_btc”的行，特别是我想要将所有元素放入一个变量中，所以“小数位数”、“最小价格”等等，所有这些都在{}括号之间，但只针对“ltc_btc”行

因此，请仅此：

{"decimal_places":5,"min_price":0.1,"max_price":1600,"min_amount":0.01,"hidden":0,"fee":0.2},"ltc_btc":

如何从该行获取变量？我也在使用JSON.Net。

你不能这么做。您必须反序列化所有JSON，然后从反序列化对象中检索该行。

“ltc\u btc”

不是终点。在继续之前，您应该先了解一下

JSON

对象。
