那DB层 怎么把数据放到treeView控件中?
追答
public DataTable GetDate()
{
DataTable dt = new DataTable();
dt.Columns.Add("ID", typeof(Int32));
dt.Columns.Add("Name", typeof(string));
//..其他字段
DbConnection conn = .....
DbCommand cmd = conn.CreateCommand();
cmd.CommandText = "select * from ....";
DbDataReader reader = cmd.ExecuteReader();
while(reader.Read())
{
DataRow row = dt.CreateRow();
row["ID"] = reader["ID"];
row["Name"] = reader["Name"];

dt.Rows.Add(row);
