FilterName.Clear();
string connectionString = "Provider=Microsoft.JET.OLEDB.4.0;data source=" + strPath;
OleDbConnection conn = new OleDbConnection(connectionString);
string sql = "SELECT DISTINCT "+stringColName+" From " + strTable;
OleDbCommand cmd = new OleDbCommand(sql, conn);

朋友你好.
我们使用数据库.即Provider = Microsoft.JET.OLEDB.4.0;
我的应用程序还从数据库甚至树节点中获取了整个数据..
我想知道如何对树状子进行排序...
代码是:
hello friends.
we use a database.i.e Provider=Microsoft.JET.OLEDB.4.0;
my application fetch the whole data from the database even tree node also..
i want to know how to do the sorting of tree child...
code is :
List<string> reeList = new List<string>();
FilterName.Clear();
string connectionString = "Provider=Microsoft.JET.OLEDB.4.0;data source=" + strPath;
OleDbConnection conn = new OleDbConnection(connectionString);
string sql = "SELECT DISTINCT "+stringColName+" From " + strTable;
OleDbCommand cmd = new OleDbCommand(sql, conn);
conn.Open();
OleDbDataReader reader;
reader = cmd.ExecuteReader();
TreeNode tn = null;
tn=new TreeNode(ParentNode);
while(reader.Read())
{
tn.Nodes>Add(reader.GetString(0),reader.GetString(0))
FilterName.Add(reader.GetString(0));
}</string></string>
请告诉我这段代码是如何完成树孩子的工作的.
