Enumerate list of MVC Model validation errors in code-behind

Question

Within MVC 3, is there a mechanism that allows the enumeration of all validation errors before returning the resulting View?

For Example:

if (!ModelState.IsValid)
{
 //Enumerate validation errors
}

Answer 1

Description

You can loop through the ModelStateValues collection

Sample

if (!ModelState.IsValid)
{
 foreach (ModelState modelState in ModelState.Values) {
 foreach (ModelError error in modelState.Errors) {
 // error.ErrorMessage contains the error message
 }
 }
}
