问题描述
foreach (string key in HttpContext.Current.Request.Form.AllKeys)
{
string value = HttpContext.Current.Request.Form[key];
}
上述代码的.net核心版本是什么?似乎.net core删除了 AllKeys ,而是将其替换为 Keys .我试图将上面的代码转换为.net核心方式,但是它引发了无效的操作异常.
What is the .net core version of the above code? Seems like .net core took out AllKeys and replaced it with Keys instead. I tried to convert the above code to the .net core way, but it throws an invalid operation exception.
HttpContext.Request.Form ='HttpContext.Request.Form'引发了类型为'System.InvalidOperationException'的异常
HttpContext.Request.Form = 'HttpContext.Request.Form' threw an exception of type 'System.InvalidOperationException'
转换后的代码:
foreach (string key in HttpContext.Request.Form.Keys)
{
}
推荐答案
您可以使用此功能:
var dict = Request.Form.ToDictionary(x => x.Key, x => x.Value.ToString());
在这种情况下,您可以遍历字典或直接访问值:
In that case, you can iterate over your dictionary or you can access values directly:
dict["Hello"] = "World"
