Singleton pattern for a property in c#

Singleton pattern for a property in c#

I am trying to adapt singleton policy for my CsvConfiguration Property.
If the configuration is already available, just return the configuration.
else, get the configuration and return the same and I am able to build
this code.
public Rootpdf pdfConfiguration
{
get
{
Rootpdf pdfConfiguration = null;
try
{
if (pdfConfiguration == null)
{
//retrieve the configuration file.
//load the configuration and return it!
}
else
{
return pdfConfiguration;
}
}
catch (Exception e)
{
Log.Error("An error occurred while reading the
configuration file.", e);
}
return pdfConfiguration;
}
}
Advantages (i hope): Whenever my pdfConfiguration is wanted, if already it
is available, i can return it. Need not load the configuration file
eachtime and calculate the configuration.
My Query: The resharper! The resharper tells that the code
if (pdfConfiguration == null) //The expression is always true.
Is it really a problem with resharper that it doesn't understand I am
following this singleton pattern ?
or
Am I not following singleton pattern at all?
