How to get TFS health check error message by code?

Question

I already know a WorkItem.Validatemethod can get ArrayListfields in this work item that are invalid ( msdn ).

But they seem to contain only invalid fields and, therefore, names, but do not contain any error messages, that is why they are invalid, which is useful for sending a work item without using the TFS built-in controls. How to get a hint with an error like "new error 1: TF200012: the Title field cannot be empty."?

For a better understanding, see the figure.
 I am using Chinese language VS2010 SP1, and the error description is translated as above.

Visual Studio is another client that wraps TFS error messages. You cannot fix TF * errors, but you can receive FieldStatusand print your own message.

var invalidFields = workItem.Validate();
if (invalidFields.Count > 0)
{
    foreach (Field field in invalidFields)
    {
        string errorMessage = string.Empty;
        if (field.Status == FieldStatus.InvalidEmpty)
        {
            errorMessage = string.Format("{0} {1} {2}: TF20012: field \"{3}\" cannot be empty."
                , field.WorkItem.State
                , field.WorkItem.Type.Name
                , field.WorkItem.TemporaryId
                , field.Name);
        }
        //... more handling here

        Console.WriteLine(errorMessage);
    }
}
else // Validation passed
{
    workItem.Save();
}
