数据列表 ASP.net c# 循环

本文关键字:循环 net ASP 列表 数据 | 更新日期: 2023-09-27 18:31:23

我有一个数据列表,它从包含服务器名称的SQL数据库中提取数据。(6 的 )

我想遍历数据列表,并为列表中的每个服务器使用 WMI 连接到它,看看值是否为真。

我有一个服务器名称,但当我将其与数据列表组合时则不然。

我哪里出错了?

谢谢

 string SARHServerName = "";
 //SARHServerName = reader["ServerName"].ToString();
 ConnectionOptions con = new ConnectionOptions();
 con.Username = "Username";
 con.Password = "Password";
 foreach (DataListItem item in DataList.Items)
 {
      Label1.Text = SARHServerName;
      SARHServerName += "," + ((Label)    (item.FindControl("ServerNameLabel"))).Text;
      ManagementScope scope =
        new ManagementScope(
        "''''" + SARHServerName + "''root''CIMV2''TerminalServices", con);
      scope.Options.EnablePrivileges = true;
      scope.Options.Authentication = AuthenticationLevel.PacketPrivacy;
      scope.Options.Impersonation = ImpersonationLevel.Impersonate;
      scope.Connect();
      //create object query
      ObjectQuery query = new ObjectQuery("SELECT * FROM Win32_TerminalServiceSetting");
      //create object searcher
      ManagementObjectSearcher searcher =
                                            new ManagementObjectSearcher(scope,     query);
      //get collection of WMI objects
      ManagementObjectCollection queryCollection = searcher.Get();
      //enumerate the collection.
      foreach (ManagementObject m in queryCollection)
      {
          if (m["Logons"].ToString() == "0")
          {
              ((Image)(item.FindControl("ServerDown"))).Visible = true;
              ((Image)(item.FindControl("ServerUP"))).Visible = false;
          }
          else
          {
              ((Image)(item.FindControl("ServerDown"))).Visible = false;
              ((Image)(item.FindControl("ServerUP"))).Visible = false;
          }
       }
  }

一旦我将数据源绑定到数据列表,我就会调用此函数。

public void GetDataFromSQLGridView()
{
SqlConnection conn = null;
    try
     {
conn = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["DailyChecksConnectionString"].ConnectionString);
            {
                conn.Open();
                using (SqlCommand cmd =
                    new SqlCommand("SELECT ServerName FROM Servers_Checks", conn))
                {
                    DataListSQL.DataSource = cmd.ExecuteReader();
                    DataListSQL.DataBind();
                }
            }
        }
        catch { }
        finally { GetRemoteDesktop(); }

}

会是我的 SQL 命令吗?看起来它一次性从SQL返回所有服务器名称,而不是返回一个然后继续并拉取另一条记录。

好的,我找到了一些关于此的进一步信息。我做了一个

Response.Write(SARHServerName);
Response.Write("<br />");

它通过循环很好,但它像这样连接结果

server1
server1server2
server1server2server3
server1server2server3server4
server1server2server3server4server5
server1server2server3server4server5server6

我必须接近吗?

更改:

SARHServerName = ((Label)    (item.FindControl("ServerNameLabel"))).Text;
