Question

I’m coding a tool to count all entries in a table. My question is, how can I get all the tables of an existing database? I’m using Microsoft SQL Server 2008 R2 and I already have a method to get a string array of a table:

List<string> lResult = new List<string>();
        SqlConnection sqlConn10 = new SqlConnection(sConnStr);
        sqlConn10.Open();
        SqlCommand sqlComm10 = new SqlCommand("SELECT " + sColumn + " FROM " + sTable + " WHERE " + sWhere, sqlConn10);
        SqlDataReader myReader10 = sqlComm10.ExecuteReader();
        int i = 0;
        try
        {
            while (myReader10.Read())
            {
                lResult.Add(myReader10.GetString(0));
                i++;
            }
        }
        catch
        {
            myReader10.Close();
            sqlConn10.Close();
        }

        return lResult.ToArray();
}

Either you use the sql-command

select * from sys.tables

or you use a DataTable

DataTable dt = SQLConnection.GetSchema("Tables");
foreach (DataRow row in dt.Rows)
{
 ...
}
