如何在请求中显示所有语言？

Question

octokit.net

我要按语言过滤查询

var request = new SearchRepositoriesRequest("mvc client side framework")
{
   // how about we restrict the language the library is written in?
    Language = Language.JavaScript
}

如何使所有语言再次出现在请求中？
像这样：

Language = Language.All

Answer 1

属性Language可为空，所以Language = null可能为空吗？
