Marc Borgers commented on LOG4NET-112:
--------------------------------------
The problem is located in a the routine that does the conversion from hostname
to the ipaddress in IPAddressConverter TryParse does not work.
Here is what I did and what seems to work. I replaced the callback with my own
to work around the proble:
public object ConvertFrom(object source)
{
string str = source as string;
if (str != null && str.Length > 0)
{
try
{
// It seems that TryParse, used in the
Log4Net code does not work
if
(str.Trim(validIpAddressChars).Length == 0)
{
try
{
// try to parse the
string as an IP address
return
IPAddress.Parse(str);
}
catch(FormatException)
{
// Ignore a
FormatException, try to resolve via DNS
}
}
// Try to resolve via DNS. This is a
blocking call.
IPHostEntry host =
Dns.GetHostByName(str);
if (host != null &&
host.AddressList != null &&
host.AddressList.Length > 0 &&
host.AddressList[0] != null)
{
return host.AddressList[0];
}
}
catch(Exception ex)
{
throw
ConversionNotSupportedException.Create(typeof(IPAddress), source, ex);
}
}
throw
ConversionNotSupportedException.Create(typeof(IPAddress), source);
}
