System.Web.HttpUtility.UrlEncode を使用してエンコードしている大きな URL があります。エンコードすると、実際の例のようにエンコードされません。問題が何であるかはわかりませんが、おそらく別のキャラクタータイプか何かです.作成されると思われるものと実際に作成されるものの例を挙げます。助けてくれてありがとう、私はこれで迷っています。

最初の例では、URL が二重にエンコードされているようです。デコードされた sparams パラメータを見ると、次のように表されます。

sparams=id%2Citag%2Csource%2Cip%2Cipbits%2Cexpire

あなたの2番目の例では

sparams=id,itag,source,ip,ipbits,expire

したがって、最初の例で起こっていることは、最初に値に対して UrlEncode を実行していることです。この値を使用して URL を構築し、構築された URL に対して UrlEncode を実行します。

UPDATE :これは、クエリ文字列の値に UrlEncoded が必要な値が含まれている場合に従う一般的な方法です (例: & space ? など)。

w3c標準によると、あなたの例は問題ありません。%252 記号はありません。

あなたの URL はかなり異なっており、あなたが望んでいるのかどうかわからない先頭の文字もあります。
