Visual Basic .NET (VB.NET) is a multi-paradigm, object-oriented programming language, implemented on the .NET Framework. Microsoft launched VB.NET in 2002 as the successor to its original Visual Basic language. VB.Net is a simple, modern, object-oriented computer programming language developed by Microsoft to combine the power of .NET Framework and the common language runtime with the productivity benefits that are the hallmark of Visual Basic.

iam creating DLL where i created a function

Public Sub BindListControl( ByVal Lst As Listbox, ByVal sql As String, ByVal TextField As String, Optional ByVal ValueFld As String = "")
Dim ds As New DataSet
Dim Ad As New SqlDataAdapter
Dim Cmd As New SqlCommand

Try
If cnn2.State = ConnectionState. Closed Then OpenConnection2( )

With Cmd
.Connection = cnn2
.CommandType = CommandType. Text
.CommandText = sql
End With
Ad = New SqlDataAdapter( Cmd)
Ad.Fill(ds, "tmp")
Lst.DataTextField = TextField
If ValueFld <> "" Then
Lst.DataValueField = ValueFld
End If
Lst.DataSource = ds
Lst.DataBind( )

Catch ex As Exception
Current.Response. Write(ex. Message)
Finally

Ad.Dispose()
Cmd.Dispose( )
'cnn2.Close( )
End Try
End Sub
------------ --------- --------- --------- --------- --------- -
and Then i replaced function with Object
------------ --------- --------- --------- --------- --------- -

Public Sub BindListControl( ByVal Lst As Object, ByVal sql As String, ByVal TextField As String, Optional ByVal ValueFld As String = "")
Dim ds As New DataSet
Dim Ad As New SqlDataAdapter
Dim Cmd As New SqlCommand

Try
If cnn2.State = ConnectionState. Closed Then OpenConnection2( )

Current.Response. Write(ex. Message)
Finally

It will sucessfully work but if do it in c# as

public void BindListBox( ListBox Lst, string sqlquery, string TextField, string value)
{
//ListBox Lst;
//Lst = (ListBox)sender;
SqlConnection con = new SqlConnection( );
con.ConnectionStrin g = cnnstring;
con.Open();
if (con.State.ToString () == "Open")
{
SqlDataAdapter adapater = new SqlDataAdapter( sqlquery, con);
DataSet Ds = new DataSet();
SqlCommandBuilder cmd = new SqlCommandBuilder( adapater) ;
try
{

adapater.Fill( Ds, "temp");
Lst.DataTextField = TextField;
if (value != null)
{
Lst.DataValueField = value;
}
Lst.DataSource = Ds;
Lst.DataBind( );


}

catch (Exception ex)
{
Response.Write( ex.Message. ToString( ));
}
finally
{
con.Close();
adapater.Dispose( );
cmd.Dispose( );
}

}
else
{
Response.Write( "Connection Not Available");
}
}
--------------------------------------
It will work with ListBox control
-----------------------------------
if i replace ListBox with Object it will through Error that object does not contain defination for DataTextField, DataSource, DataBind( )
so sir it will work in vb.net why not in c# is any alternate way to do this or any other syntax
please send me response as earily as possible

Destructors are used to de-allocate resources i.e. to clean up after an object is no longer available.

Finalize is the destructor which is normally used. Finalize is called automatically when the .NET runtime determines that the object is no longer being used. Using the Finalize method in code looks like this:

Public Class Form1 Inherits System.Windows.Forms.Form
Dim obj1 as new Class1 ()
End Class
Public Class Dest
Protected overrides Sub Finalize()
? calling the Finalize method
End Sub
End Class
