使用string.Format()连接Concat阿拉伯和英语字符串 [英] Concat arabic and english string with string.Format()

问题描述

使用concat两个字符串遇到一些麻烦.

Have some trouble with concat two string.

return string.Format("{0}{1}{2}",
            IdWithSubType,

            ExtraInfo.Any(info => info.InfoType == UniExtraInfoType.Alias)
            ? string.Format(" ({0})", string.Join(",", ExtraInfo.First(info => info.InfoType == UniExtraInfoType.Alias).Info))
            : "",

            Context != null
            ? string.Format(" ({0})", Context.IdWithSubType)
            : "");

当IdWithSubType，extrainfo和context具有拉丁或基里尔符号时是可以的，但是IdWithSubType可以是阿拉伯语，并且与之连接是错误的. 例如100252575)طائراتهليكوبت@ vk.com) 阿拉伯符号和其他符号混合在一起，但是我需要类似这里是阿拉伯字符串"([e-mail].如果使用String.Format解决此问题，那就太好了.希望对您有所帮助.谢谢

it's ok when IdWithSubType, extrainfo and context has latin or kirillic symbols, but IdWithSubType can be arabic, and concat with that is wrong. e.g.100252575)طائرات هليكوبت@vk.com) arabic and other symbols mixed, but i need something like "here arabic string" ([e-mail]. it would be great if this problem have solve with String.Format. Hope for your help. Thank you

推荐答案

可能没有编码问题出现，只是RTL(从右到左)字符串作为LTR(从左到右)字符串的一部分遵循排列方式

It's likely no encoding issues appear there, just how RTL (right-to-left) string follows arrangement as part of LTR (left-to-right) string.

双向格式化中通常使用2个字符来标记LTR和RTL部分，分配为 0x200e (LTR)& 0x200f (RTL).在这种情况下，请使用0x200e标记RTL部分的结尾(阿拉伯语)并开始LTR部分:

There's 2 characters which commonly used in bidirectional formatting to mark either LTR & RTL part, assigned as 0x200e (LTR) & 0x200f (RTL). In this case, use 0x200e to mark end of RTL part (in Arabic) and starting LTR part:

string leftToRight = ((char)0x200E).ToString();

// using string.Format
return string.Format("{0}{1}{2}{3}",
            IdWithSubType,
            leftToRight,

            ExtraInfo.Any(info => info.InfoType == UniExtraInfoType.Alias)
            ? string.Format(" ({0})", string.Join(",", ExtraInfo.First(info => info.InfoType == UniExtraInfoType.Alias).Info))
            : "",

            Context != null
            ? string.Format(" ({0})", Context.IdWithSubType)
            : "");,

// alternative: using string.Join
return string.Join(leftToRight, IdWithSubType,
            ExtraInfo.Any(info => info.InfoType == UniExtraInfoType.Alias)
            ? string.Format(" ({0})", string.Join(",", ExtraInfo.First(info => info.InfoType == UniExtraInfoType.Alias).Info))
            : "",

            Context != null
            ? string.Format(" ({0})", Context.IdWithSubType)
            : "");,
