源码：

string searchText = this.TextBox3.Text;
            StringBuilder sb = new StringBuilder();
            sb.Append("select * from UpLoad where Resourse_Title like '%");
            sb.Append(searchText);
            sb.Append("%'or Resourse_JianJie like '%");
            sb.Append(searchText);
            sb.Append("%'");

            OleDbConnection conn = new OleDbConnection();
            conn.ConnectionString = "Provider = Microsoft.JET.OleDb.4.0;Data Source=CHANGSHA-DB5D6B;Initial Catalog=User_Iformations;Integrated Security=True";
            conn.Open();
            OleDbCommand cmd = new OleDbCommand(sb.ToString(), conn);
            OleDbDataReader da = cmd.ExecuteReader();
            this.Repeater1.DataSource = da;
            this.Repeater1.DataBind();
            da.Dispose();
            conn.Close();

错误源：行 128:            conn.Open();
