ASP.NET MVC Custom ModelMetadataProvider and Model

问题:

In my ASP.NET MVC application, I have metadata based model defined in database. I have a custom object defining the metadata of the data and uses dataset for DTO. To display this, I am planning to write a custom ModelMetadataProvider and ModelValidatorProvider.

Is this the right approach?

Any pointers on custom ModelMetadataProvider and ModelValidatorProvider?

回答1:

The last day or so I was trying to figure out the same. It seems that writing a custom ModelMetadataProvider and ModelValidatorProvider is the way to go if you have metadata / validation configuration stored on database, some file or wherever.

I found this a great starting point.

Did you in the meantime already hacked together a solution? HTH,
