1.字段过长截取字符串

1.1 截取字符串类

 

可以直接substring也可以<%# Utility.Common.GetShow( Eval("NewTitle").ToString(),20,true) %>    <%#fcwms.Common.GetContent.GetShow(Eval("com_address").ToString(), 19, true)%>         /// 
        /// 按字节数截取字符串,中文算两个字节,全角字符算两个字节,大写字母也算两个字节        /// 
        /// 要处理的字符串        /// 要保留的字节数        /// 设置截取后加不加省略号( "... ")默认的传true        /// 
              public static string GetStrByByteCount(string strSrc, int count, bool withPoint)        {            Regex regex = new Regex("[\u4e00-\u9fa5]+", RegexOptions.Compiled);            char[] stringChar = strSrc.ToCharArray();            StringBuilder sb = new StringBuilder();            int nLength = 0;            bool isCut = false;            for (int i = 0; i < stringChar.Length; i++)            {                if ((regex.IsMatch((stringChar[i]).ToString())) || (stringChar[i] > 65280 && stringChar[i] < 65375) || (stringChar[i] > 64 && stringChar[i] < 91))                {                    nLength += 2;                    if (nLength > count)                    {                        isCut = true;                        break;                    }                    sb.Append(stringChar[i]);                }                else                {                    nLength = nLength + 1;                    if (nLength > count)                    {                        isCut = true;                        break;                    }                    sb.Append(stringChar[i]);                }            }            if (isCut)            {                if (withPoint)                {                    return sb.ToString() + "...";                }                else                {                    return sb.ToString();                }            }            else            {                return sb.ToString();            }        }

 

1.2 示例

 

无提示：

 <td><%#fcwms.Common.GetContent.GetShow(Eval("com_address").ToString(),19,true)%></td> 

2.时间格式化

<%# Convert.ToDateTime(Eval("time")).ToString("yyyy-MM-dd HH:mm")%> <%#string.Format("{0:yyyy-MM-dd HH:mm}", Eval("time"))%> <%#string.Format("{0:g}",Eval("add_time"))%>   2018/4/2 15:03

3.合并单元格

 <td runat="server" id="tdName"><%#Eval("td_name")%></td> 

rptList.DataSource = pds;        rptList.DataBind();　　　　　//合并方法放到数据邦定之后        for (int i = rptList.Items.Count - 1; i > 0; i--)        {            HtmlTableCell oCell_Previous = rptList.Items[i - 1].FindControl("tdName") as HtmlTableCell;            HtmlTableCell oCell = rptList.Items[i].FindControl("tdName") as HtmlTableCell;            oCell.RowSpan = (oCell.RowSpan == -1) ? 1 : oCell.RowSpan;            oCell_Previous.RowSpan = (oCell_Previous.RowSpan == -1) ? 1 : oCell_Previous.RowSpan;            if (oCell.InnerText == oCell_Previous.InnerText)            {                oCell.Visible = false;                oCell_Previous.RowSpan += oCell.RowSpan;            }        }
