the copy method takes the source file then the destination file then true. you are perhaps doing it opposite. it should be like shown below. System.IO.File.Copy(sourceFile, destFile, true ); if outputFilepath is your source file then test with a static file path for destination and test.

System.IO.File.Copy(OutputfilePath, Path.Combine(exportDirectory, fileName), true ); System.Diagnostics.Debug.WriteLine(myValue2) \192.168.2.7\ImportExport	estImporter System.Diagnostics.Debug.WriteLine(exportDirectory) \192.168.2.7\ImportExport	estImporter\5 System.Diagnostics.Debug.WriteLine(OutputfilePath) \192.168.2.7\ImportExport	estImporter\DeliveryGeneration_Output.xlsx System.Diagnostics.Debug.WriteLine(Path.Combine(exportDirectory, fileName)) \192.168.2.7\ImportExport	estImporter\5\orignal-e1f75892-7c35-4533-b2ff-ddc8e9893733.xlsx System.Diagnostics.Debug.WriteLine(ex) System.IO.IOException: The target file '\192.168.2.7\ImportExport	estImporter\5\orignal-e1f75892-7c35-4533-b2ff-ddc8e9893733.xlsx' is a directory, not a file. at System.IO.FileSystem.CopyFile(String sourceFullPath, String destFullPath, Boolean overwrite) at System.IO.File.Copy(String sourceFileName, String destFileName, Boolean overwrite)

yes, for testing purpose make your destination path static for a moment and test, if it works then there are lots of possible scenario but first do it make you destination as string dest= 'http:\192.168.2.7/importexport	estimporter/deliveryGeneration.xlx' ;
