选择Query sql C＃如何将结果输出到DataGrid

Question

如何将精炼查询的结果输出到名为“customerDataGridView”的数据网格视图？

string strCon = Properties.Settings.Default.PID2dbConnectionString;

using (OleDbConnection conn = new OleDbConnection(strCon)) {
   conn.Open();
   string strSql = "SELECT  * FROM customer WHERE City =Belfast";
   OleDbDataAdapter adapter = new OleDbDataAdapter(new OleDbCommand(strSql, conn));
}

谢谢你的帮助！

Answer 1

尝试这样的ASP.Net：

DataSet ds = new DataSet();
OleDbDataAdapter oledbAdapter = New OleDbDataAdapter(strSql, connection);
oledbAdapter.Fill(ds);
customerDataGridView.DataSource = ds.Tables(0);
customerDataGridView.DataBind();

或类似于WinForms的东西：

DataSet ds = new DataSet();
OleDbDataAdapter oledbAdapter = New OleDbDataAdapter(strSql, connection);
oledbAdapter.Fill(ds);
customerDataGridView.DataSource = ds.Tables(0);

祝好运。

Answer 2

在您的代码后尝试以下内容：

DataTable table = new DataTable();
adapter.Fill(table);
customerDataGridView.AutoGenerateColumns = True
customerDataGridView.Datasource = table;

Answer 3

尝试这个

DataSet ds = new DataSet();
OleDbDataAdapter oda = New OleDbDataAdapter(strSql, conn);
oda.Fill(ds);
customerDataGridView.DataSource = ds.Tables(0);

对于winform控件，您不需要DataBind()
