.Net中如何操作IIS(源代码) 及iis的属性(2)

            newVirDir.Invoke("AppCreate",true);
            newVirDir.CommitChanges();
            rootfolder.CommitChanges();
            //然后更新数据
            UpdateDirInfo(newVirDir,newdir);
        }
        catch(Exception ee)
        {
            throw new Exception(ee.ToString());
        }
    }
    else
    {
        throw new Exception("This virtual directory is already exist.");
    }
}
//得到一个虚拟目录
public VirtualDirectory GetVirDir(string strVirdir)
{
    VirtualDirectory tmp = null;
    if(_virdirs.Contains(strVirdir))
    {
        tmp = _virdirs.Find(strVirdir);
        ((VirtualDirectory)_virdirs[strVirdir]).flag = 2;
    }
    else
    {
        throw new Exception("This virtual directory is not exists");
    }
    return tmp;
}

//更新一个虚拟目录
public void Update(VirtualDirectory dir)
{
    //判断需要更改的虚拟目录是否存在
    if(_virdirs.Contains(dir.Name))
    {
        DirectoryEntry ode = rootfolder.Children.Find(dir.Name,"IIsWebVirtualDir");
        UpdateDirInfo(ode,dir);
    }
    else
    {
        throw new Exception("This virtual directory is not exists.");
    }
}
　
//删除一个虚拟目录
public void Delete(string strVirdir)
{
    if(_virdirs.Contains(strVirdir))
    {
        object[] paras = new object[2];
        paras[0] = "IIsWebVirtualDir"; //表示操作的是虚拟目录
        paras[1] = strVirdir;
        rootfolder.Invoke("Delete",paras);
        rootfolder.CommitChanges();
    }
