C#寫的字串截取函數

protected string CutString(string str,int length) 

{
string
newString="";
if(str!="")
{
if(str.Length>length)
{

newString=str.Substring(0,length)+"...";
}
else
{

newString=str;
}
}
return newString;
}

然後在綁定的時候：

<%#
CutString(DataBinder.Eval(Container.DataItem,"NewTitle").ToString(),5) %>

 截取中英文混合字串

public static string getStr(string s,int l)
    {   
    string temp = s
;
    if
(Regex.Replace(temp,"[\u4e00-\u9fa5]","zz",RegexOptions.IgnoreCase).Length<=l)
   
{
        return temp;
    }
    for (int
i=temp.Length;i>=0;i--)
    {
        temp =
temp.Substring(0,i);
        if
(Regex.Replace(temp,"[\u4e00-\u9fa5]","zz",RegexOptions.IgnoreCase).Length<=l-3)
       
{
            return temp + "";
        }   
    }
    return
"";
    }
調用：
string content = "同樣會突然認同和法國回複回複規劃";
content =
getStr(content,13);
