星空多行文本控件数字类型字符对齐方法

     星空多行文本控件数字类型字符对齐方法

开发项目上有时需要在多行文本控件中写入不同栏位的信息，但写入数字后对齐方式设置经常出现错位，没法对齐如下图：

   考虑到大部分项目中统计金额不会超过13位数（不包含小数点部分），业务上最大的13位数9999999999999是玖万玖千玖佰玖拾玖亿 玖千玖佰玖拾玖万 玖千玖佰玖拾玖，因此按13位数，保留两位小数点来显示汇总结果，不足13位的补空格显示，保证统计金额靠右对齐。

开发过程中发现，不同长度保留2位小数点按千分位格式展示的字符串需要补空格的位数如下图：

.1.1.1  主要代码：

/**

        * 获取字符串的字节长度,不考虑中文字节

        *

        * @param chstring

        * @return

        */

        public static int CalLength(String chstring)

        {

            int length = 0;

            if (chstring.IsNullOrEmptyOrWhiteSpace())

                return 0;

            for (int i = 0; i < chstring.Length; i++)

            {

                char c = chstring.CharAt(i);

                length += 1;

            }

            return length;

        }

        public static String FullWithBank(String chstring,int bankLen)

        {

            int chlen = CalLength(chstring);

            String spance = " ";

            StringBuilder sb = new StringBuilder();

            for (int i = 0; i < bankLen; i++)

            {

                sb.Append(spance);

            }

            return sb.ToString() + chstring;

        }

       /**

       * 保留2位小数点小于或等于13位数字格式的字符串，不足13位的用空格符显示，保证数字靠右对齐。

       * 主要是因为千分位格式的数字，补空格符的引起靠右对齐问题

       * @param chstring（保留2位小数点小于或等于13位数字，字符串格式）

       * @return chstring
