将特定的列从一个Excel电子表格复制到C＃中的另一列

Question

I have been trying to make a simple app to merge information from one excel spreadsheet to another in c#. But I don't find any reference about how could I do this.

enter image description here

I have the info in one spreadsheet and I need to copy that information in another spreadsheet file.

How can do this? Thanks in advance.

Here is another thing you may want to try out (the code uses GemBox.Spreadsheet library ):

ExcelFile source = ExcelFile.Load("Source.xlsx");
ExcelColumn sourceColumn = source.Worksheets[0].Columns[0];

ExcelFile destination = ExcelFile.Load("Destination.xlsx");
ExcelColumn destinationColumn = destination.Worksheets[0].Columns[0];

int count = source.Worksheets[0].Rows.Count;
for (int i = 0; i < count; i++)
    destinationColumn.Cells[i].Value = sourceColumn.Cells[i].Value;

destination.Save("Destination.xlsx");
