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
        }
    }
}
