c# - 使用SQL查询结果填充datagridview

我正在尝试显示查询结果，但是我一直得到一个空白的数据网格。
就像数据本身不可见

这是我的代码:

 private void Employee_Report_Load(object sender, EventArgs e)
 {
     string select = "SELECT * FROM tblEmployee";
     Connection c = new Connection();
     SqlDataAdapter dataAdapter = new SqlDataAdapter(select, c.con); //c.con is the connection string
     SqlCommandBuilder commandBuilder = new SqlCommandBuilder(dataAdapter);

     DataTable table = new DataTable();
     table.Locale = System.Globalization.CultureInfo.InvariantCulture;
     dataAdapter.Fill(table);
     bindingSource1.DataSource = table;

     dataGridView1.ReadOnly = true;
     dataGridView1.DataSource = bindingSource1;
}

此代码有什么问题？

最佳答案

这是您的固定代码。接下来忘记绑定(bind)源

 var select = "SELECT * FROM tblEmployee";
 var c = new SqlConnection(yourConnectionString); // Your Connection String here
 var dataAdapter = new SqlDataAdapter(select, c);

 var commandBuilder = new SqlCommandBuilder(dataAdapter);
 var ds = new DataSet();
 dataAdapter.Fill(ds);
 dataGridView1.ReadOnly = true;
 dataGridView1.DataSource = ds.Tables[0];
