Answer 1

在Windows窗體創建一個從數據庫中TreeView和C＃LINK

private void PopulateTreeView(int parentId, TreeNode parentNode) 
{ 
    String Seqchildc = "SELECT MENUPARVAL,FRM_NAME,MNUSUBMENU FROM MNUSUBMENU WHERE MENUPARVAL=" + parentId + ""; 
    SqlDataAdapter dachildmnuc = new SqlDataAdapter(Seqchildc, conn); 
    DataTable dtchildc = new DataTable(); 
    dachildmnuc.Fill(dtchildc); 
    TreeNode childNode; 
    foreach (DataRow dr in dtchildc.Rows) 
    { 
     if (parentNode == null) 
      childNode = treeView1.Nodes.Add(dr["FRM_NAME"].ToString()); 
     else 
      childNode = parentNode.Nodes.Add(dr["FRM_NAME"].ToString()); 
      PopulateTreeView(Convert.ToInt32(dr["MNUSUBMENU"].ToString()), childNode); 
    } 
}
