我的代码在这里：

var context = new Mock<HttpContextBase>();
var response = new Mock<HttpResponseBase>();

context.SetupProperty(c => c.Response = response);

我尝试使用Setup().返回()和SetupGet()但我不断收到以下错误：

“Property or Indexer ‘System.Web.HttpContextBase.Response’ cannot be assigned to — it is read only.

我试过谷歌搜索并在这个网站上搜索,但我似乎无法找到答案.
