数据表“nrong”中有列“title”中储存文章的标题长度50个字符,现在在页面中用“Repeater”控件显示标题,希望只显示前40个字符,要怎样操作呀?
------解决方案--------------------------------------------------------
- C# code
写个扩展方法吧public static Left(this string source, int subLength){ return source == null ? string.Empty : source.SubString(0, source.Length >=subLength ? subLength : source.Length);}<%# ((string)Eval("title")).Left(40) %>或<%# new string(((string)Eval("title") ?? string.Empty).Take(40).ToArray())%>
------解决方案--------------------------------------------------------
写个方法
public string GetTitle(object title, int length)
{
string strTitle = title.ToString();
if (strTitle.Length > length)
{
strTitle = strTitle.Substring(0, length) + "...";
}
return strTitle;
}
数据绑定时:
<%#GetTitle(Eval("Title"), 12)%>
