textarea 设置英文换行的css

<textarea style="word-break:break-all; table-layout:fixed;">as sql where as sql where as sql where as sql wherewhere where where where where where where where where where where where where where where where where where where where where where where where where where where where where where where where where where where where where where where where where where where where where where where where </textarea>

 

如果让textarea中显示正常的空格和回车：
.ToString().Replace("\r\n", "<br>").Replace(" ", "&nbsp;")

将数据库中的相应字符转换回来。
