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。
