    SqlDataAdapter myAdapter = new SqlDataAdapter(cmd);
    DataSet MyDataSet = new DataSet();
    myAdapter.Fill(MyDataSet, "Departments");
    object[] rowVals = new object[3];

    foreach (DataTable myTable in MyDataSet.Tables)
    {
        foreach (DataRow myRow in myTable.Rows)
        {
            foreach (DataColumn myColumn in myTable.Columns)
            {

推荐答案

    foreach (DataRow myRow in MyDataSet.Tables[0].Rows)
    {
        TextBox1.Text = myRow["DeptNo"].ToString(); 
        TextBox2.Text = myRow["DeptId"].ToString(); 
        ... 
    }
