C#：如何向已经存在的HttpResponseMessage对象添加匿名类型？

// 原始的HttpResponseMessage对象
HttpResponseMessage originalResponse = new HttpResponseMessage(HttpStatusCode.OK);
originalResponse.Content = new StringContent("Hello World");

// 创建新的HttpResponseMessage对象
HttpResponseMessage newResponse = new HttpResponseMessage(originalResponse.StatusCode);
newResponse.Content = originalResponse.Content;

// 添加匿名类型的属性
var additionalData = new { Key1 = "Value1", Key2 = "Value2" };

// 将匿名类型的属性添加到新的HttpResponseMessage对象中
foreach (var property in additionalData.GetType().GetProperties())
{
    property.SetValue(newResponse, property.GetValue(additionalData));
}

// 使用新的HttpResponseMessage对象进行后续操作
