用程序修改iis 日志记录属性?

[skykittey]

请问怎么用C#程序修改iis站点的 日志记录属性 呢?
在网上找了很久都没找到. 麻烦高手说下吧..

我的代码老是返回 UNKONWN ERROR (0X80005000)

const string WebServerSchema = "IIsWebServer"; // Case Sensitive
string ServerName = "LocalHost";
DirectoryEntry W3SVC = new DirectoryEntry("IIS://" + ServerName + "/W3SVC");
foreach (DirectoryEntry Site in W3SVC.Children)
{
if (Site.SchemaClassName == WebServerSchema)
{
Console.WriteLine("WebSite Instance ID : " + Site.Name);
foreach (string PropertyName in Site.Properties.PropertyNames)
{
Console.WriteLine(PropertyName);
PropertyValueCollection pvc = Site.Properties[PropertyName];
foreach (object Value in pvc)
Console.WriteLine(" " + Value.ToString());
}
}
Console.WriteLine("".PadRight(80, '-'));
