C#用datagridview数据绑定不显示

Question

private void btnAdd_Click(object sender, EventArgs e)
{
string connString = "Data Source=.;Initial Catalog=txl;Integrated Security=true";
string sql = "select * from information";
SqlConnection conn = new SqlConnection(connString);
SqlDataAdapter da = new SqlDataAdapter(sql, conn);
DataSet ds = new DataSet();
da.Fill(ds,"custom");
dataGridView1.DataSource = ds.Tables["custom"];

}

        数据库的information表里有内容，为什么运行后绑定的数据不显示。

Answer 1

你添加列了吗，并且为列设置对应字段了吗
