    public string SubstringLength(string strTemp,int intLen, bool AddPoint)
    {
        string strApp = "";        int strLength = System.Text.Encoding.Default.GetBytes(strTemp).Length;        if (strLength > intLen)
        {
            strApp = strTemp.Substring(0, intLen);
            if (AddPoint == true) strApp += "...";
        }
        else
        {
            strApp = strTemp.ToString();
        }        //****返回重新构造的字符
        return strApp;
    }//****调用函数
<%#SubstringLength(DataBinder.Eval(Container.DataItem,"Context").ToString(),4,true)%>//****第二种方法用SQL
SELECT *,CASE WHEN LEN(CONTEXT)>4 THEN SUBSTRING(CONTEXT,0,4)+'...' ELSE CONTEXT END AS CONTEXTNAME FROM TB_INFO

是在ASP.NET中写这个函数吗?
有在HTML绑定的时候做判断的吗?

我记得好像css2.0里有这个功能

你参考一下下面的代码吧<html xmlns:rdl>

Re:弹出错误“SubstringLength”方法没有采用“1”个参数的重载
因为绑定的是一个字段,函数中的参数为三个.....//*****将下面的函数写在后台,然后在前台调用即可./// <summary>
