The easiest way to create a file on disk in .Net is with AppendAllText.

Thanks. I want to create a CSV file in workflow and store it in repository. The data for CSV file will come from Laserfiche Form

Priya

I was able to figure it out. Here is the code I used to create a CSV in a Workflow SDK Script straight into the repository from a MemoryStream object. No need to save the CSV as a temp file.

Protected Overrides Sub Execute()
	'Write your code here. The BoundEntryInfo property will access the entry, RASession will get the Repository Access session
	'Wrap the code in a Try/Catch to catch any errors...

	'Create variables for connecting to the repository
	Dim serverName As String = "LFServer", repoName As String = "LFRepository"
	Dim username As String = "Workflow", password As String = "WFPassword"
	
	'Retreive FilePath from the Workflow Token
	Dim filePath as String = GetTokenValue("FilePath")  'CSV will be stored in the current folder
	Dim folder as FolderInfo

	'Declare variables for each column
	Dim col1 as String  'Will go in Column1 of the CSV
	Dim col2 As String 'Will go in Column2 of the CSV
	Dim col3 as String  'Column 3 of the CSV
	Dim numRows As Integer = GetTokenValue("RowCount")

	'Declare variables for building the CSV file in memory
	Dim strm As New MemoryStream
	Dim csvWriter As StreamWriter
	Dim csvData As StringBuilder
	Dim lineText As String
	Dim enc As ASCIIEncoding = new ASCIIEncoding()

	Try
		Dim repository As New RepositoryRegistration(serverName, repoName)
		csvData = New StringBuilder()    'We will append all of the data to this string object

		'Build the text for the CSV FIle into a StringBuilder object
		For Index As Integer = 1 To numRows
			col1 = TokenReplace("%(Column1#["+Index.ToString+"]#)")
			col2 = TokenReplace("%(Column2#["+Index.ToString+"]#)")
			col3 = TokenReplace("%(Column3#["+Index.ToString+"]#)")
			lineText = TokenReplace("%(Column1#["+Index.ToString+"]#)"+","+"%(Column2#["+Index.ToString+"]#)"+","+"%(Column3#["+Index.ToString+"]#)")
			csvData.AppendLine(lineText)
		Next Index

		
		Using session As New Session()
			session.LogIn(username, password, repository)
			' Create a new csv document in the LF System Accounts folder under the current folder
			Dim docInfo As New Laserfiche.RepositoryAccess.DocumentInfo(session)
			folder = Laserfiche.RepositoryAccess.Folder.GetFolderInfo(filePath, session)
			docInfo.Create(folder, "index.csv", "LF SYSTEM ACCOUNTS", EntryNameOption.AutoRename)

			'Create a document importer object and tie it to the newly created csv document
			Dim importer as DocumentImporter = new DocumentImporter()
			importer.Document = docInfo

			'Import the StringBuilder object into a byte array and convert to a MemoryStream
			Dim b as Byte() = System.Text.Encoding.UTF8.GetBytes(csvData.ToString())
			strm = New MemoryStream(b)
			importer.ImportEDoc("text/csv", strm)   'Import MemoryStream into CSV
			strm.Close
		End Using

		'Cleanup...
		csvWriter = Nothing
		csvData = Nothing

	Catch ex As Exception
		'Send any error messages to workflow so they can be tracked...
		WorkflowApi.TrackError(ex.message)
	End Try
End Sub

Make sure you update the Server Name, Repository Name and Credential variables to login to the repository.
