How to resolve the following error in a C# console application using VS2010: "The process cannot access the file 'error.txt' because it is being used by another process."

I am developing a C# console application using VS2010 and in the following snippet of code, when the following statement is executed:

 File.Delete(errorFilePath)

Open in new window


I get the error:
"The process cannot access the file 'L:\\F\FS\\C\\TEST\\error.txt' because it is being used by another process."

------------------------------------------------------

static void Main()
        {            
            string errorFilePath = System.IO.Path.Combine(MyGlobals.BASE_DIR, "error.txt");
           
            //delete the error file if it presently exists so that a new error file can be created in the event any errors are discovered
            if (File.Exists(errorFilePath))
            {
                File.Delete(errorFilePath);
            }            

            DirectoryInfo parentDirectory = new DirectoryInfo(MyGlobals.BASE_DIR);

            foreach (FileInfo file in parentDirectory.GetFiles())
            {
                if (!string.Equals(file.Name, MyGlobals.BASE_FILE_Name + ".ard", StringComparison.InvariantCultureIgnoreCase) &&
                    !string.Equals(GetFileTitleOnly(file.Name), GetFileTitleOnly(currentRunningAssembly.ManifestModule.Name), StringComparison.InvariantCultureIgnoreCase))
                {
                    StreamWriter sw1 = new StreamWriter(errorFilePath);
                    ProcessFile(file.FullName, sw1);               
                }
            }

            //if an Error file was created but no information was written to it, then the error file will be deleted 
            //before the application is finished and closes down
            if (File.Exists(errorFilePath))
            {
                if (new FileInfo(errorFilePath).Length == 0)
                {
                    if (File.Exists(errorFilePath))
                    {
                        File.Delete(errorFilePath);       <---- Error occurs here
                    }
                }
            }
           
        }

Try closing your StreamWriter just after line 19.

Did you check, may be your file was opened in some editor like Notepad?

Also, seems you are not closing your stream (streamwriter)...
