Searching Datatable in c# and OLEDB

Hi User/Gust,

Please Explain Exact Requirement. I Confuse about your Requirement. So Generally I Suggest Multiple Example or Different Way you can implement your requirement.
First
-----
This program accesses the BugTypes.mdb database, creates a dataset, adds the tables to it, and displays the number of tables, columns, and rows. It also displays the titles of each row.
----------------------------------------------------------------------------------
using System;
using System.Data;
using System.Data.OleDb;
using System.Xml.Serialization;

public class MainClass {
public static void Main ()
{
// Set Access connection and select strings.
// The path to BugTypes.MDB must be changed if you build
// the sample from the command line:
#if USINGPROJECTSYSTEM
string strAccessConn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=..\\..\\BugTypes.MDB";
#else
string strAccessConn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=BugTypes.MDB";
#endif
string strAccessSelect = "SELECT * FROM Categories";

// Create the dataset and add the Categories table to it:
DataSet myDataSet = new DataSet();
OleDbConnection myAccessConn = null;
try
{
myAccessConn = new OleDbConnection(strAccessConn);
}
catch(Exception ex)
{
Console.WriteLine("Error: Failed to create a database connection. \n{0}", ex.Message);
return;
}

try
{

OleDbCommand myAccessCommand = new OleDbCommand(strAccessSelect,myAccessConn);
OleDbDataAdapter myDataAdapter = new OleDbDataAdapter(myAccessCommand);

myAccessConn.Open();
myDataAdapter.Fill(myDataSet,"Categories");

}
catch (Exception ex)
{
Console.WriteLine("Error: Failed to retrieve the required data from the DataBase.\n{0}", ex.Message);
return;
}
finally
{
myAccessConn.Close();
}

// A dataset can contain multiple tables, so let's get them
// all into an array:
DataTableCollection dta = myDataSet.Tables;
foreach (DataTable dt in dta)
{
Console.WriteLine("Found data table {0}", dt.TableName);
}

// The next two lines show two different ways you can get the
// count of tables in a dataset:
Console.WriteLine("{0} tables in data set", myDataSet.Tables.Count);
Console.WriteLine("{0} tables in data set", dta.Count);
// The next several lines show how to get information on
// a specific table by name from the dataset:
Console.WriteLine("{0} rows in Categories table", myDataSet.Tables["Categories"].Rows.Count);
// The column info is automatically fetched from the database,
// so we can read it here:
Console.WriteLine("{0} columns in Categories table", myDataSet.Tables["Categories"].Columns.Count);
DataColumnCollection drc = myDataSet.Tables["Categories"].Columns;
int i = 0;
foreach (DataColumn dc in drc)
{
// Print the column subscript, then the column's name
// and its data type:
Console.WriteLine("Column name[{0}] is {1}, of type {2}",i++ , dc.ColumnName, dc.DataType);
}
DataRowCollection dra = myDataSet.Tables["Categories"].Rows;
foreach (DataRow dr in dra)
{
// Print the CategoryID as a subscript, then the CategoryName:
Console.WriteLine("CategoryName[{0}] is {1}", dr[0], dr[1]);
}

}
}
----------------------------------------------------------------------------------
Output

The Categories table of the BugTypes.mdb database contains the following information.

Category ID Category Name

This example uses an OleDbDataAdapter to fill a DataTable using an ADO Recordset. This example assumes that you have created an ADO Recordset

OleDbDataAdapter custDA = new OleDbDataAdapter();
DataSet custDS = new DataSet();
DataTable custTable = new DataTable("Customers");
custTable.Columns.Add("CustomerID", typeof(String));
custTable.Columns.Add("CompanyName", typeof(String));
custDS.Tables.Add(custTable);
//Use ADO objects from ADO library (msado15.dll) imported
// as.NET library ADODB.dll using TlbImp.exe
ADODB.Connection adoConn = new ADODB.Connection();
ADODB.Recordset adoRS = new ADODB.Recordset();
adoConn.Open("Provider=SQLOLEDB;Data Source=localhost;Initial Catalog=Northwind;Integrated Security=SSPI;", "", "", -1);
adoRS.Open("SELECT CustomerID, CompanyName FROM Customers", adoConn, ADODB.CursorTypeEnum.adOpenForwardOnly, ADODB.LockTypeEnum.adLockReadOnly, 1);
custDA.Fill(custTable, adoRS);
adoRS.Close();
adoConn.Close();
