Streamwriter need shareread while write is happening

[kenz987]

private StreamWriter sw;
sw = File.AppendText(sPath); // Open the path for writing
sw.WriteLine(sLine); // Append a new line to the file
sw.Close();
I am writing text to a file and sometimes a second indicator will be reading that text while the first process has it locked, causing the second indi to abort, even tho it is in a try, catch block
So I either need parms to share the file, or a way to catch the abort of the second indi and retry the read. Thanks, Ken

Hello kenz987,

In general what you are doing will not work as expected because two items cannot share access to a file at the same time. The two scripts are not going to work in unison to read/write/close.

What specifically are you trying to do with the shared file or what is its purpose in your scripts?

You likely need to use a C# structure for what you are trying to do if you mean to share some data, writing/reading a file is only realistic if the rate at which the read/write occur is spaced out so they are not conflicting.

I look forward to being of further assistance.

OK, skip that, But why did the second indi abort, the error was in a try/catch block??? Is there any way to keep an indi alive no matter the errors?

Hello kenz987,

I couldn't say without a specific example. There is not a way to keep the indicator alive in case of errors, the platform expects to stop it in case of an error. Generally we just suggest to avoid using try/catch so that you can catch the very first exception and not allow the script to move past that point. This helps in debugging.


Please let me know if I may be of additional assistance.
