Test explorer tool - mail wrapper class section question

See more:

C#

Hello deoxys,
I need to ask a question regarding the MailWrapper.cs file within the Test Explorer project. I am debugging this code and keep getting stuck at the parameter "_DLFile" where it is coming back with a null exception:

See line #20 string _DLFile = "Tools\\Settings\\EmailDL.cfg";

"An unhandled exception of type 'System.ArgumentNullException' occurred in mscorlib.dll

Additional information: Value cannot be null."


Can you help explain why this is so?

What I have tried:

In your code, you defined a path on line #20 called:

string _DLFile = "Tools\\Settings\\EmailDL.cfg";

I tried setting the path to mine and ensured the file was placed in the folders there as shown below:

string _DLFile = "C:\\drop\\Debug\\Tools\\Settings\\EmailDL.cfg";
