这是try catchPowerShell 2.0中的
$urls = "http://www.google.com", "http://none.greenjump.nl", "http://www.nu.nl"
$wc = New-Object System.Net.WebClient 
foreach($url in $urls)
{
    try
    {
        $url
        $result=$wc.DownloadString($url)
    }
    catch [System.Net.WebException]
    {
        [void]$fails.Add("url webfailed $url")
    }  
}
但是我想做的是C#
catch( WebException ex)
{
    Log(ex.ToString());
}
这可能吗?
