Hi Everyone,
I'm sure this is a beginner's error but I cannot figure it out. I
keep getting the following error:
The process cannot access the file 'C:\Users\Public\Documents\Cerf Pen
App\DesktopApps\cs\GetPenInformation\bin\x86\Debug\cerf-servers.txt'
because it is being used by another process.
Here is my code:
File.Create(UserCerfServerListFileLocation);
using (StreamWriter sw = new
StreamWriter(UserCerfServerListFileLocation, true))
{
foreach (KeyValuePair<string, CerfServer> pair in
servers)
{
sw.WriteLine(pair.Value.toCommaSeparatedString());
}
}
Any help is greatly appreciated. Thank you.
