c# httpclient发送请求报错

在c#当中使用httpclient发送http请求，代码如下：

string customTableServiceUrl = "https://localhost:5001/api/XXX/";
    
HttpClient httpClient = new HttpClient();

httpClient.DefaultRequestHeaders.Accept.Clear();
httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Delete,
	customTableServiceUrl + "CLEVER/entries/2006");

var apiResponse = await httpClient.SendAsync(request);

但是在执行的时候却报错如下：

The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.

在定义HttpClient的代码前加上一行代码解决了我的问题：

  ServicePointManager.ServerCertificateValidationCallback = delegate { return true; };
