Question

我有一个＆＃34;搜索＆＃34;按钮搜索数据网格中的数据/单元格，这是源mysql db。下面的代码块是成功搜索一个列，但是当我为其他列添加而不是搜索功能时，它不能很好地工作，并且大部分都不会带来结果。同样给出了区分大小写的错误，这对于只有一列来说不是问题。

如何安排代码以便能够搜索所有行和列？

private void btnSearch_Click(object sender, EventArgs e)
        {
            DataView DV = new DataView(dbdataset);
            DV.RowFilter = string.Format("Name LIKE '%{0}%'", txtSearch.Text);
            dgvEkip.DataSource = DV;

            // I added those columns below for search function as well but did not work well
            /*
            DV.RowFilter = string.Format("Telephone LIKE '%{0}%'", txtSearch.Text);
            DV.RowFilter = string.Format("Email LIKE '%{0}%'", txtSearch.Text);
            DV.RowFilter = string.Format("Surname LIKE '%{0}%'", txtSearch.Text);
            DV.RowFilter = string.Format("City LIKE '%{0}%'", txtSearch.Text);
            DV.RowFilter = string.Format("Adress LIKE '%{0}%'", txtSearch.Text);
            */
        }

非常感谢，Nuri。

Answer 1

使用AND加入这样的条件：

DV.RowFilter = string.Format("Telephone LIKE '%{0}%' AND Email LIKE '%{0}%'", txtSearch.Text, txtSearch2.Text);

您希望在逻辑OR中添加更多条件：例如

public class Team
    {
        public Team ParentTeam;
        public string Name;

        int Level
        {
            get
            {
                int i = 0;
                Team p = this.ParentTeam;
                while (p != null)
                {
                    i++;
                    p = p.ParentTeam;
                }
                return i;
            }
        }

        static IEnumerable<Team> Sort(IEnumerable<Team> list)
        {
            return list.OrderBy(o => o.Level);
        }
    }
