RichTextBox选中项居中
如题,并不是让整个文本居中
所以
C# code
 TextAlignment align = TextAlignment.Left;

                switch ((this.cmbStyles.SelectedValue as ComboBoxItem).Tag.ToString())
                {
                    case "左对齐":
                        align = TextAlignment.Left;
                        break;
                    case "居中":
                        align = TextAlignment.Center;
                        break;
                    case "右对齐":
                        align = TextAlignment.Right;
                        break;
                }

类似就不要一变又一遍的再发了。。。

                    align = TextAlignment.Right;
                    break;
            }
            //将样式赋给富文本框的选中项
            rtb_text.Selection.ApplyPropertyValue(Block.TextAlignmentProperty, align);
