    Yet another way to get a list of tables in an ADO.net-supported database:

    System.Data.Common.DbConnection con =
    this.command.Connection as System.Data.Common.DbConnection ;

    if ( con != null )
    {
    System.Data.DataTable temp = con.GetSchema
    (
    "TABLES"
    ) ;

    temp.DefaultView.RowFilter = "TABLE\_TYPE='TABLE' OR TABLE\_TYPE='BASE TABLE'" ;
    temp.DefaultView.Sort = "TABLE\_NAME" ;

                You can use this code to check if a table exists.

                IF EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[MyTable]') AND type in (N'U'))
                PRINT 'MyTable exists.'
                ELSE
                PRINT 'MyTable does not exist.'

                  try with this..

                  If Object_ID('dbo.MyTable') IS NOT NULL
                  PRINT 'MyTable Exists'
                  Else
                  PRINT 'MyTable Not Exists'

                      If there is a view or stored procedure with the same name, this script will fail.
