IIS进程资源定期回收
IIS6常见的性能调优方案中设置进程自动回收时间就是一种方法,用代码同样可以实现之,或者在什么样的时间有选择性的回收指定的应用程序池:
使用C#代码操作的就是上图中的回收工作进程,单位分钟,默认好像是1740分钟吧,没有意义:
using System.DirectoryServices; //先引用此命名空间,IIS7据说已经是有新的API private void button1_Click(object sender, EventArgs e) { string method = this.comboBox1.Text; //Start开启 Recycle回收 Stop 停止 string AppPoolName = this.comboBox2.Text; if (method == "") { this.label4.Text = "AppPoolName and method is required!"; return; } if (AppPoolName == "") { this.label4.Text = "AppPoolName and method is required!"; return; } try { DirectoryEntry appPool = new DirectoryEntry(this.textBox2.Text.Trim()); DirectoryEntry findPool = appPool.Children.Find(AppPoolName, "IIsApplicationPool"); findPool.Invoke(method, null); appPool.CommitChanges(); appPool.Close(); MessageBox.Show("应用程序池(" + method + ")操作成功", "启动成功", MessageBoxButtons.OK, MessageBoxIcon.Information); } catch (Exception ex) { MessageBox.Show(ex.Message, "启动失败", MessageBoxButtons.OK, MessageBoxIcon.Error); } } private void Form1_Load(object sender, EventArgs e) { try { DirectoryEntry appPool = new DirectoryEntry(this.textBox2.Text.Trim()); foreach (DirectoryEntry dirPool in appPool.Children) { if (dirPool.SchemaClassName == "IIsApplicationPool") { comboBox2.Items.Add(dirPool.Name); } } } catch (Exception ex) { } } |
写成Window Service 或者Console给计划任务定期跑就可以了。
