I am developing a Windows application. The source is stored on a
network share, probably 6 directories deep.

When I say:

File.CreateText("G:\temp\" & _dataSourceInfo.Csv_filename)

the file is created OK on the local disk G in directory temp. However,
when I say:

File.CreateText("%temp%\" & _dataSourceInfo.Csv_filename)

it fails with a Directory not found, and is trying to create:

\\networkShare\...\Application\bin\%temp%\CSV_Filename

Why is this happening? Something to do with security?

TIA Lars
 
I guess I have to do this instead:


Dim tempDirectory As String =
Environment.GetEnvironmentVariable("temp")
File.CreateText(tempDirectory & "\" & _dataSourceInfo.Csv_filename)

but I still don't understand why the runtime is using relative
addressing with the original code.

Click to expand...

If you are using more than one environment variable in the string,
'Environment.ExpandEnvironmentVariables' is a good alternative.
