糯米玩PC: SNMP # NET

HOME : http://www.snmpsharpnet.com
免費的 SNMP LIB => http://sourceforge.net/projects/snmpsharpnet/files/

API Document =>http://www.docs.snmpsharpnet.com/docs-0-9-1/

在 Examples 頁籤中，有簡單的範例:
Demonstrate how to use SNMP#Net library.

------------------------------------------------------------------------------------

以下，我使用該Lib ，為ASI_Guard 撰寫了一個僅使用Request 資訊的使用者物件

如何使用:

  

/* IP 預設值 */

string IP_AsiGuard1 = "10.5.120.101";

string IP_AsiGuard2 = "10.5.120.102";

string IP_IPGuard1 = "10.5.120.100";

  

private void StartSnmpPulling()

  {

     /* 啟動 SNMP pulling */

            uiAsiGuard1.run(IP_AsiGuard1);

            uiAsiGuard2.run(IP_AsiGuard2);

            uiIpGuard1.run(IP_IPGuard1);

        }

uiAsiGuard.Designer.cs

namespace TVBS_SSNMP

{

    partial class uiAsiGuard

    {

        /// <summary> 

        /// 設計工具所需的變數。

        /// </summary>

        private System.ComponentModel.IContainer components = null;

  

        /// <summary> 

        /// 清除任何使用中的資源。

        /// </summary>

        /// <param name="disposing">如果應該處置 Managed 資源則為 true，否則為 false。</param>

        protected override void Dispose(bool disposing)

        {

            if (disposing && (components != null))

            {

                components.Dispose();

            }

            base.Dispose(disposing);

        }
