22APR09^CAN^HGH^FM9352^757^0755^0955^1^1^1^QA64670@VA60630@WA52550@FAFF1580

截取"Airs_0至^&","Airs_1至^&","Airs_2至^&"的数据并用DataTable显示到DataGrid里面????

Answer 1

使用正则表达式
[code=C#]
using System.Text.RegularExpressions;        private void button1_Click(object sender, EventArgs e)
        {
            string str = @"&Airs_0=22APR09^CAN^HGH....";
            Regex reg = new Regex(@"Airs_\d.*?\^&");
            MatchCollection matchs = reg.Matches(str);            DataTable dt = new DataTable();
            dt.Columns.Add("col1", typeof(string));            DataRow dr;
            foreach (Match m in matchs)
            {
                dr = dt.NewRow();
                dr[0] = m.Value;
                dt.Rows.Add(dr);
            }
            this.dataGridView1.DataSource = dt;
        }

Answer 2

Regex re = new Regex(@"(?<=Airs_[^=]+=).*?(?=\^&)");
Match m = re.Match(input);
while(m.Success)
{
    Console.WriteLine(m.Value);
    m = m.NextMatch();
}
/*结果
22APR09^CAN^HGH^JD5169^319^0745^0950^1^1^1^YAYY1050@BA92970
22APR09^CAN^HGH^FM9352^757^0755^0955^1^1^1^QA64670@VA60630@WA52550@FAFF1580@YAYY1050
22APR09^CAN^HGH^CA1353^73G^0800^0955^1^1^1^VA56590@F6FF1580@YAYY1050@BA92970
