示例1: SetMemberErrors
/// <summary>
/// Inherited from <see cref="IValidationManager"/>.
/// <para>
/// This manager assumes all objects within <paramref name="validationResult"/> are of type <see cref="ValidationResult"/>.
/// </para>
/// <para>
/// This manager removes all <see cref="ValidationResult"/> objects from the property represented by <paramref name="member"/>.
/// If any of the removed <see cref="ValidationResult"/> objects are present for any other properties on the object, those are removed as well.
/// </para>
/// <remarks>This effectively means that if a single ValidationResult spans multiple properties, and one of those properties changes (i.e. is revalidated)
/// then the ValdiationResult will be removed from all of the spaned properties.</remarks>
/// </summary>
/// <param name="errorCollection">A <see cref="ValidationErrorCollection"/> that houses the validation results.</param>
/// <param name="validationResult">A <see cref="IEnumerable{T}"/> that represents the collection of validation issues that need to be applied to <paramref name="errorCollection"/>.</param>
/// <param name="member">A string representing the name of the property that is being validated.</param>
