为什么我删除了listview中的值，数据库中没删除呢

Question

string connstr = "Provider=Microsoft.Jet.OleDb.4.0;";
connstr += @"Data Source=D:\Merger20150208_caohuan\GEARCNC.mdb";
OleDbConnection tempconn = new OleDbConnection(connstr);//连接数据库

            OleDbDataAdapter thisAdapter = new OleDbDataAdapter("select * from GrindingWheelInformation", tempconn);

            OleDbCommandBuilder thisBuilder = new OleDbCommandBuilder(thisAdapter);//CommandBuilder用来创建SQL指令，与DataAdapter相关联

            DataSet thisDataSet = new DataSet();
            thisAdapter.Fill(thisDataSet, "GrindingWheelInformation");//MY_N_AIT不是表名而是DataTable对象的名称


            listView1.Items.Remove(listView1.SelectedItems[0]);
            thisAdapter.Update(thisDataSet, "GrindingWheelInformation");//跟新数据库中的值

Answer 1

你只执行了listView1.Items.Remove，没看到执行delete的sql
