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.

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( )
