c# comboBox模糊匹配

c# comboBox模糊匹配，

1.系统提供了顺序的匹配方式。

 comboBox1.AutoCompleteMode = AutoCompleteMode.SuggestAppend;
 comboBox1.AutoCompleteSource = AutoCompleteSource.ListItems;

 本方法的确定是必须是从前往后依次匹配。如：数据项中有“中国人民”，想输入“人民”查询，结果为空。

2.自己动手做匹配：vs2008

 dtModel = new DataTable();
 string sql1 = "SELECT REPORT_TEMPLATE_CODE ,REPORT_TEMPLATE_NAME FROM REPORT_TEMPLATE WHERE BARGAIN_FORMAT='0' ";
 SystemInfo.dbData.Retrieve(sql1, dtModel);                                
 foreach (DataRow dr in dtModel.Rows)
 {
     comboBox1.Items.Add(new ReportName(dr["REPORT_TEMPLATE_CODE"].ToString(), dr["REPORT_TEMPLATE_NAME"].ToString()));
 }
 comboBox1.TextUpdate+=new EventHandler(comboBox1_TextUpdate);

 private void comboBox1_TextUpdate(object sender, EventArgs e)
        {
            string key = this.comboBox1.Text;
            DataTable dttemp = dtModel.Clone();
            comboBox1.Items.Clear();
            if (!string.IsNullOrEmpty(key))
            {
                DataRow[] drs = dtModel.Select(string.Format(" REPORT_TEMPLATE_NAME like '%{0}%' ", key));
                if (drs != null && drs.Length > 0)
                {
                    foreach (DataRow drow in drs)
                    {
                        dttemp.Rows.Add(drow.ItemArray);
                    }
                }
            }
            else
            {
              dttemp=dtModel;
            }
            foreach (DataRow dr in dttemp.Rows)
            {
                comboBox1.Items.Add(new ReportTemplet(dr["REPORT_TEMPLATE_CODE"].ToString(), dr["REPORT_TEMPLATE_NAME"].ToString()));
            }
            comboBox1.Select(comboBox1.Text.Length, 0);
            comboBox1.DroppedDown = true;
            Cursor = Cursors.Default;
        }
