C# HttpRequestMessage是否支持GET

是的，C#中的HttpRequestMessage类支持GET请求。可以通过设置HttpRequestMessage对象的Method属性为HttpMethod.Get来发送GET请求。例如：

using System; using System.Net.Http; using System.Threading.Tasks;  class Program {     static async Task Main(string[] args)     {         using (HttpClient client = new HttpClient())         {             HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Get, "https://api.example.com/data");             HttpResponseMessage response = await client.SendAsync(request);              if (response.IsSuccessStatusCode)             {                 string responseBody = await response.Content.ReadAsStringAsync();                 Console.WriteLine(responseBody);             }             else             {                 Console.WriteLine("Request failed with status code: " + response.StatusCode);             }         }     } } 

在上面的示例中，我们创建了一个GET请求，指定了请求的URL为"https://api.example.com/data"。然后使用HttpClient发送该请求，并等待响应。如果响应成功，则将响应内容打印到控制台上。
