C# – How to detect if page load in newly-started browser process fails

asp.netc++error-logginglogging

I use Process.Start("firefox.exe", "http://localhost/page.aspx");
And how i can know page fails or no?
OR
How to know via HttpWebRequest, HttpWebResponse page fails or not?

When i use

HttpWebRequest myReq = (HttpWebRequest)WebRequest.Create("somepage.aspx");
HttpWebResponse loWebResponse = (HttpWebResponse)myReq.GetResponse();
Console.Write("{0},{1}",loWebResponse.StatusCode, loWebResponse.StatusDescription);

how can I return error details?

Not need additional plugins and frameworks. I want to choose this problem only by .net

Any Idea please

Use Watin to automate firefox instead of Process.Start. Its a browser automation framework that will let you monitor what is happening properly.

C# – How to detect if this dictionary key exists in C#

You can use ContainsKey:

if (dict.ContainsKey(key)) { ... }

or TryGetValue:

dict.TryGetValue(key, out value);

Update: according to a comment the actual class here is not an IDictionary but a PhysicalAddressDictionary, so the methods are Contains and TryGetValue but they work in the same way.

Example usage:

PhysicalAddressEntry entry;
PhysicalAddressKey key = c.PhysicalAddresses[PhysicalAddressKey.Home].Street;
if (c.PhysicalAddresses.TryGetValue(key, out entry))
{
    row["HomeStreet"] = entry;
}

Update 2: here is the working code (compiled by question asker)

PhysicalAddressEntry entry;
PhysicalAddressKey key = PhysicalAddressKey.Home;
if (c.PhysicalAddresses.TryGetValue(key, out entry))
{
    if (entry.Street != null)
    {
        row["HomeStreet"] = entry.Street.ToString();
    }
}

...with the inner conditional repeated as necessary for each key required. The TryGetValue is only done once per PhysicalAddressKey (Home, Work, etc).
