Dim row As Integer
Dim column As Integer
Dim rowCount As Integer
Dim columnCount As Integer
Dim stream As Stream
Dim flags As TextFileSaveFlags
Dim rowDelimiter As String
Dim columnDelimiter As String
Dim cellDelimiter As String
Dim encoding As Encoding
Dim value As IAsyncAction
 
value = instance.SaveTextFileRangeAsync(row, column, rowCount, columnCount, stream, flags, rowDelimiter, columnDelimiter, cellDelimiter, encoding)

public IAsyncAction SaveTextFileRangeAsync( 
   int row,
   int column,
   int rowCount,
   int columnCount,
   Stream stream,
   TextFileSaveFlags flags,
   string rowDelimiter,
   string columnDelimiter,
   string cellDelimiter,
   Encoding encoding
)

Parameters

row: The starting row index.
column: The starting column index.
rowCount: The number of rows.
columnCount: The number of columns.
stream: The stream to which to save the range text.
flags: The export flags.
rowDelimiter: The row delimiter string.
columnDelimiter: The column delimiter string.
cellDelimiter: The cell delimiter string.
encoding: The encoding.

Return Value

true if the data is saved to the stream successfully; otherwise, false.

Exceptions
