请问一下各位高手，小弟写了一个段遍历数据库的代码：
string path = @"D:\a.txt";
FileStream f = new FileStream(path, FileMode.Open);
StreamWriter sw = new StreamWriter(f,Encoding.UTF8);
DateTime t = System.DateTime.Now;
string strConnection = "Data Source=221.208.168.124;User ID=sa;Password=sa@123456";
SqlConnection sqlConnetion = new SqlConnection(strConnection);
string strDbas = "SELECT Name FROM Master..SysDatabases ORDER BY Name";
SqlDataAdapter adpterDtbase = new SqlDataAdapter(strDbas, strConnection);
DataTable dtbase = new DataTable();
adpterDtbase.Fill(dtbase);
sqlConnetion.Close();
try
{
sw.WriteLine("一共有" + dtbase.Rows.Count.ToString() + "数据库 ");
for (int u = 0; u < dtbase.Rows.Count; u++)
{
string sql = "Data Source=221.208.168.124;Initial Catalog=" + dtbase.Rows[u][0].ToString() + ";User ID=sa;Password=sa@123456";
SqlConnection conn = new SqlConnection(sql);
sw.WriteLine("数据库的名称为" + dtbase.Rows[u][0].ToString());
string strSql = "SELECT Name FROM " + dtbase.Rows[u][0].ToString() + "..SysObjects ORDER BY Name";
SqlDataAdapter adpterDt = new SqlDataAdapter(strSql, conn);
DataTable dt = new DataTable();
adpterDt.Fill(dt);
try
{
sw.WriteLine("一共有" + dt.Rows.Count.ToString() );
