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。
