#Declaration

public Task<byte[]> SaveDocumentAsync(
    DocumentFormat format,
    CancellationToken cancellationToken,
    IProgress<int> progress
)

#Parameters

Name Type Description
format DocumentFormat

An enumeration member that specifies the output document format.

cancellationToken CancellationToken

A cancellation token that indicates whether to cancel the operation.

progress IProgress<Int32>

An object used to report the task progress in percentage. Use a Progress<T> class instance to report progress.

#Returns

Type Description
Task<Byte[]>

Returns a byte array that contains document data in the specified format.

#Remarks

You can use this SaveDocumentAsync method overload to store a workbook in an external database.

Important

Take into account the following when you call this method:

  • The events fired by this method call may occur in a different thread than the target operation.

  • The operation is not thread safe (the document should not be accessed simultaneously by different threads). Wait until the operation is completed before you continue to work with the document (for example, use the await operator).

#Calculate Formulas Before Save Operation

The default calculation mode for a Workbook is Manual. This mode implies that the Spreadsheet does not calculate formulas before it saves a document. Call the Workbook.Calculate or Workbook.CalculateFull method to calculate all formulas in the workbook.
