warning SYSLIB0014: “WebRequest.Create(string)”已过时:“WebRequest, HttpWebRequest, ServicePoint, and WebClient are obsolete. Use HttpClient instead.” (https://aka.ms/dotnet-warnings/SYSLIB0014)
解决方案：
使用HttpClient
C# 全选
string url = "https://api64.ipify.org/";
using (HttpClient client = new HttpClient())
{
HttpResponseMessage response = await client.GetAsync(url);
response.EnsureSuccessStatusCode();
ip = await response.Content.ReadAsStringAsync();
}
