推荐答案

为了设置版本，您必须创建 HttpRequestMessage 并设置其传递给版本属性（ v = vs.118）.aspxrel =nofollow noreferrer> HttpClient.SendAsync 。您可以使用帮助 HttpVersion 实用程序类：

In order to set the version you'll have to create an instance of HttpRequestMessage and set its Version property which you pass to HttpClient.SendAsync. You can use the helper HttpVersion utility class:

var requestMessage = new HttpRequestMessage 
{
    Version = HttpVersion.Version10
}; 

var client = new HttpClient();
var response = await client.SendAsync(requestMessage);
