这是排序ValidationSummaryItem的源代码，希望它能帮到你

 /// <summary>
        /// Compare ValidationSummaryItems for display in the ValidationSummary
        /// </summary>
        /// <param name="x">The first reference used for comparison.</param>
        /// <param name="y">The second reference used for comparison.</param>
        /// <returns>The result of the comparison check between the two references.</returns>
        internal static int CompareValidationSummaryItems(ValidationSummaryItem x, ValidationSummaryItem y)
        {
            int returnVal;
            if (!ReferencesAreValid(x, y, out returnVal))
            {
                // Do a null comparison check if one (or both) are null
                return returnVal;
            }

            // Compare ErrorSource
            if (TryCompareReferences(x.ItemType, y.ItemType, out returnVal))
            {
                return returnVal;
            }

            // Compare Control

                    return returnVal;
                }

                // Both are controls

                returnVal = SortByVisualTreeOrdering(controlX, controlY);
                if (returnVal != 0)
                {
                    return returnVal;
                }

                // TabIndexes and ordering are the same, move to next check
                if (TryCompareReferences(controlX.Name, controlY.Name, out returnVal))
                {

                }
            }

            // If we reached this point, we could not compare by Control, TabIndex, nor Name.

            if (TryCompareReferences(x.MessageHeader, y.MessageHeader, out returnVal))

            }

            // Compare by ErrorMessage
            TryCompareReferences(x.Message, y.Message, out returnVal);
