做了一个功能,就是前台可以选择同一字段下面的多个不同的条件,这就涉及到了SQL语句拼接的问题。下面是一个用正则来处理查询条件

做了一个功能,就是前台可以选择同一字段下面的多个不同的条件,这就涉及到了SQL语句拼接的问题。

下面是一个用正则来处理查询条件的方法,是我目前所见到最简单的方法,现将它分享给大家。

using System.Text;

using System.Text.RegularExpressions;

string  strwhere="1,11,111,1111,";

strwhere = string.Format("select

 * from test where strwhere in ({0})",Regex.Replace(strwhere.TrimEnd(','), @"[^,]+", "'$0'"));

注:这里strwhere.TrimEnd(',')用来将1111后面的逗号去掉。
