Mvc.net 5: Allow saving and outputting HTML content

When we save the contents of the form, if one of the contents contains the HTML tag, the system will report the following error:

A potentially dangerous Request.Form value is detected from the client xxxxxxxxxxxx

To get the program to bypass this test, we can add the [allowhtml] identity to the corresponding field in the model class, as shown in:

So the HTML content will not be detected, but at the same time we need to pay attention to prevent the possibility of injection attacks, of course, this is another topic.

When we save the HTML content, if we need to export it to the page in HTML, we can use this statement:
@Html. Raw (MODEL.XXXX)
