在 C# 写入 Excel 中，如何按原样显示大数字（不使用科学记数法）？

Question

I am sending an excel file from backend. I have got long numbers for some cards' numbers. I need to show them in Excel but I want all of them to be number and edit them as it is (sometimes the value and the shown text differs, I want them to be the same).
The proplem is when I set the data type of the cell like

    var currentRow = 1;
    var cardNo = "9993232323232320";
    worksheet.Column(6).CellsUsed().SetDataType(XLDataType.Text);
    worksheet.Cell(currentRow, 6).Value = cardNo;
    worksheet.Column(6).CellsUsed().SetDataType(XLDataType.Text);//Doesn't matter if it is before or after

I can set the value with SetValue method, which makes the cell string:

worksheet.Cell(currentRow, 6).SetValue(cardNo);

But in this case, excel adds an apostrophe in front of the number, which makes it a text seemingly. When you try to edit the cell, the apostrophe exists in front of the number.

Lastly I tried to set the NumberFormatId of the cell by

    worksheet.Cell(currentRow, 6).Value = cardNo;
    worksheet.Column(6).Style.NumberFormat.NumberFormatId = 1;

For information about NumberFormatId: https://github.com/ClosedXML/ClosedXML-wiki/blob/master/NumberFormatId-Lookup-Table.md In this case the cell is a number, seemingly a number, but again when you try to edit the row, the row contains a scientific number.

I can achieve what I want over excel like this:

• Go to a column, right click, Format Cells
• Numbers tab -> Number
• Options-> Decimal Places, set to 0, Format Code set to 0. And then add a number to a row in that column.

Or like this:

• Go to a column -> right click -> format cells
• Numbers Tab -> Text -> OK. And edit the lines.

How can I achieve the same thing in ClosedXML in C#

Answer 1

Here is the wiki for number formats: https://github.com/ClosedXML/ClosedXML-wiki/blob/master/NumberFormatId-Lookup-Table.md

In the question what was trying to be achieved was this:

• Go to a column -> right click -> format cells
• Numbers Tab -> Text -> OK. And edit the lines.

By looking at the NumberFormatId table in the given link, the Id of this operation is 49 so the code must be worksheet.Column(6).CellsUsed().Style.NumberFormat.NumberFormatId = 49;

And another problem is you have to use SetValue instead of setting Value like:
worksheet.Cell(currentRow, 6).SetValue(cardNo);

After that it must work.
