Imports data from a rectangular array of objects to the specified Area. The new data will overwrite values and formulas in the target worksheet cells, but existing formatting will be preserved.

 public Area ImportData(System.Object[,] data, System.String[] columnNames, DataImportProperties props)
Public Function ImportData(ByVal data As Object(,), ByVal columnNames As String(), ByVal props As DataImportProperties) As Area

A rectangular array of values to import to the worksheet. The first dimension corresponds to row and the second to column.
Thus, an array of data { {"A","X"},{"B","Y"},{"C","Z"} } would be inserted into the worksheet as:

A

X

B

Y

C

Z

If you enable DataImportProperties.Transpose , the format will be [row][column], so:
{ {"A","B","C"},{"X","Y","Z"} } would be inserted into the worksheet as:

A

X

B

Y

C

Z

A string array of column names.

A DataImportProperties object that contains a set of properties that will determine the behavior of the data import.

An Area object representing the set of cells populated with the imported values.


DataImportProperties importProps = wb.CreateDataImportProperties();
importProps.Transpose = true;
Area importedArea = a.ImportData(dataArray, fieldNames, importProps);

Dim importProps As DataImportProperties = wb.CreateDataImportProperties()
importProps.Transpose = True
Dim importedArea As Area = a.ImportData(dataArray, fieldNames, importProps)
