把表中一行的数据显示在TEXTBOX上

[InsideBlue]

我要显示表form中，列名为form_cont的一行数据，最后一句有问题，请问该怎么写？

String conquery = "select * from form where fset_id = 579";
SqlConnection myConnection = new SqlConnection("Persist Security Info=False;User ID=sa;password =;Initial Catalog=workflow_portal;Data Source=oadb;Packet Size=4096;Workstation ID=INSIDEBLUE");
SqlDataAdapter myCommand = new SqlDataAdapter(conquery, myConnection);
DataSet ds = new DataSet();
myCommand.Fill(ds,"form");
TextBox.Text = ds.Tables["form"].Rows[0].Columns["form_cont"].ToString();

[InsideBlue]

[declude]

改为:
TextBox.Text = ds.Tables["form"].Rows[0]["form_cont"].ToString();
