[研究]ASP.NET,WebForm,將 RestSharp 106.15 改用 HttpClient 做 Restful API 呼叫(二)verify
2024-04-27
環境：Visual Studio 2022 + ASP.NET + WebForm + Web Application + C# + SQL Server 2019 + SQL Server Management Studio (SSMS) 19
因 RestSharp 於 2009 年首次推出，成為 .NET 開發者中非常受歡迎的一個選擇。在 RestSharp v107 開始，語法大改；而 .NET Framework 4.5 (2012 年推出) 開始提供 HttpClient，考慮改用這個。

實際測試，在 Visual Studio 中 Debug，v確實有拿到回傳資料。
