最近在做表單設計器，設計器上的控件都是我們自己封裝的，但每個屬性類別里的屬性是按照屬性的拼音排序的，現在想按照PropertyIndex標識進行排序（PropertyIndex的后三位是用來標識編輯器的）。

具體實現如下：

用法：

為每個屬性添加屬性：[PropertyIndex("103001000")]

比如：

[Category("掩碼")][Browsable(true)][DisplayName("掩碼類型")]//[Description("設置執行單擊事件的快捷鍵")][PropertyIndex("103001000")]public DevExpress.XtraEditors.Mask.MaskType MaskType{get{return this.BaseTextEdit.Properties.Mask.MaskType;}set{this.BaseTextEdit.Properties.Mask.MaskType = value;}}[Category("掩碼")][Browsable(true)][DisplayName("忽略空白")][Description("對于 Simple、Regular 和 RegEx 掩碼類型，MaskProperties.IgnoreMaskBlank 屬性是有效的。 如果此屬性值設置為 true，那么空白編輯器會失去焦點。 如果編輯器的取值僅部分完成，那么焦點不能被移出此編輯器，直至最終用戶輸入了完整的取值或者通過清除編輯器框而清除了取值。 如果此屬性值設置為 false，那么焦點不能移出此編輯器，直至完整輸入取值。 ")][PropertyIndex("103006000")]public bool IgnoreMaskBlank{get{return this.BaseTextEdit.Properties.Mask.IgnoreMaskBlank;}set{this.BaseTextEdit.Properties.Mask.IgnoreMaskBlank = value;}}[Category("掩碼")][Browsable(true)][DisplayName("格式占位符")][Description("對于 Simple、Regular 和 RegEx 掩碼類型，使用由 MaskProperties.PlaceHolder 屬性確定的特殊字符來呈現編輯框中的占位符。 可以使用該屬性來改變默認的占位符 (“_”符)。 對于 RegEx 掩碼類型，通過把 MaskProperties.ShowPlaceHolders 屬性設置為 false，可以隱藏占位符。 ")][PropertyIndex("103007000")]public char PlaceHolder{get{return this.BaseTextEdit.Properties.Mask.PlaceHolder;}set{this.BaseTextEdit.Properties.Mask.PlaceHolder = value;}}[Category("掩碼")][Browsable(true)][DisplayName("錯誤提示音")][Description("對于所有類型的掩碼，Boolean 型的 MaskProperties.BeepOnError 屬性都是可用的。 把此屬性設置為 true，當最終用戶試圖鍵入一個無效字符串時允許響鈴。 假定使用了 Numeric 類型的掩碼。 在這種情況下，最終用戶每次試圖鍵入非數字字符時，編輯器都將發出一段提示聲音。")][PropertyIndex("103005000")]public bool BeepOnError{get{return this.BaseTextEdit.Properties.Mask.BeepOnError;}set{this.BaseTextEdit.Properties.Mask.BeepOnError = value;}}[Category("掩碼")][Browsable(true)][DisplayName("自動填充")][Description("對于 RegEx 掩碼類型，可以啟用自動完成功能。 在這種模式中，編輯器將嘗試完成已經由最終用戶部分輸入的取值。")][PropertyIndex("103004000")]public DevExpress.XtraEditors.Mask.AutoCompleteType AutoComplete{get{return this.BaseTextEdit.Properties.Mask.AutoComplete;}set{this.BaseTextEdit.Properties.Mask.AutoComplete = value;}}[Category("掩碼")][Browsable(true)][DisplayName("保存格式字符串")][Description("對于 Simple 和 Regular 掩碼類型，可以指定是否總是把顯示的掩碼字符 (原義字符) 包括在編輯器的取值內。 換句話說，你可以控制那些字符是否出現在由 BaseEdit.EditValue 屬性返回的取值中。 要使這些字符無法被訪問，則必須把 MaskProperties.SaveLiteral 屬性設置為 false。 在這種情況下，如果顯示的取值是“(555)123-76-34”，那么由 BaseEdit.EditValue 屬性返回的取值就是“5551237634”。 ")][PropertyIndex("103008000")]public bool SaveLiteral{get{return this.BaseTextEdit.Properties.Mask.SaveLiteral;}set{this.BaseTextEdit.Properties.Mask.SaveLiteral = value;}}[Category("掩碼")][Browsable(true)][DisplayName("掩碼字符串")][Description("掩碼字符串標識了數據輸入模板。 可以使用預定義的掩碼字符串，或者構建自己的掩碼表達式, 應該根據掩碼類型來設置掩碼字符串。")][PropertyIndex("103002000")]public string EditMask{get{return this.BaseTextEdit.Properties.Mask.EditMask;}set{this.BaseTextEdit.Properties.Mask.EditMask = value;}}[Category("掩碼")][Browsable(true)][DisplayName("顯示格式占位符")][Description("對于 Simple、Regular 和 RegEx 掩碼類型，使用由 MaskProperties.PlaceHolder 屬性確定的特殊字符來呈現編輯框中的占位符。 可以使用該屬性來改變默認的占位符 (“_”符)。 對于 RegEx 掩碼類型，通過把 MaskProperties.ShowPlaceHolders 屬性設置為 false，可以隱藏占位符。 ")][PropertyIndex("103003000")]public bool ShowPlaceHolders{get{return this.BaseTextEdit.Properties.Mask.ShowPlaceHolders;}set{this.BaseTextEdit.Properties.Mask.ShowPlaceHolders = value;}}效果：

如果使用網絡上的sort排序代碼（感覺不對，于是沒有采用）：

//ArrayList propertyNames = new ArrayList();//foreach (PropertyOrderPair pop in orderedProperties)//{// propertyNames.Add(pop.Name);//}//return pdc.Sort((string[])propertyNames.ToArray(typeof(string)));效果如下：

PropertyGrid排序

Ordering Items in the Property Grid

PropertyGrid類別排序實現，可以參考：

點擊打開鏈接?

具體實現如下：

屬性控件PropertyGrid事件：

#region 屬性分組排序部分private void propertyGrid_SelectedObjectsChanged(object sender, EventArgs e){propertyGrid.Tag = propertyGrid.PropertySort;propertyGrid.PropertySort = PropertySort.CategorizedAlphabetical;propertyGrid.Paint += new PaintEventHandler(propertyGrid_Paint); }private void propertyGrid_Paint(object sender, PaintEventArgs e){var categorysinfo = propertyGrid.SelectedObject.GetType().GetField("categorys", BindingFlags.NonPublic | BindingFlags.Instance);if (categorysinfo != null){var categorys = categorysinfo.GetValue(propertyGrid.SelectedObject) as List<String>;propertyGrid.CollapseAllGridItems();GridItemCollection currentPropEntries = typeof(PropertyGrid).GetField("currentPropEntries", BindingFlags.NonPublic | BindingFlags.Instance).GetValue(propertyGrid) as GridItemCollection;var newarray = currentPropEntries.Cast<GridItem>().OrderBy((t) => categorys.IndexOf(t.Label)).ToArray();currentPropEntries.GetType().GetField("entries", BindingFlags.NonPublic | BindingFlags.Instance).SetValue(currentPropEntries, newarray);propertyGrid.ExpandAllGridItems();propertyGrid.PropertySort = (PropertySort)propertyGrid.Tag;}propertyGrid.Paint -= new PaintEventHandler(propertyGrid_Paint);} 由于我用的是：

所以在反射的時候，用的是：

GridItemCollection currentPropEntries = typeof(PropertyGrid).GetField("currentPropEntries", BindingFlags.NonPublic | BindingFlags.Instance).GetValue(propertyGrid) as GridItemCollection; 而非參考文章中的：

GridItemCollection currentPropEntries = propertyGrid1.GetType().GetField("currentPropEntries", BindingFlags.NonPublic | BindingFlags.Instance).GetValue(propertyGrid1) as GridItemCollection;

控件中的使用：

效果：

完成！
