Excel interop - 如何停止数字（存储为文本）被“评估”

问题描述

我想知道是否有人遇到了以下问题，并有任何想法如何解决它：我将数据从C＃应用程序（.NET 3.5）导出到Excel（2003）通过Interop。其中一列存储显示为数字的字符串值。也就是说，它是以0开头的数字。 000123

我需要存储完整号码，因为它可能是序列号或类似的东西。 Excel不热衷于这一点，所以我想我可以通过将目标单元格设置为一般来解决它。当我导出到Excel时，我发现123存储而不是000123。

我已经在调试中运行了应用程序，并从监视列表中发现（对于Range范围：

  range.NumberFormat =General`
 this.Rows [iGridRow] .Cells [iGridCol] .Value =000123'/ *（datagrid不截断它）* / 
 range.Value2 = 123.0 
  

尽管我在此之前设置了数字格式，似乎正在处理一个数字：

  range .NumberFormat = sNumberFormat; 
 range =（Range）sheet.Cells [iExcelRow，iExcelCol]; 
 range.Value2 = this.Rows [iGridRow] .Cells [iGridCol] .Value.ToString（）; 
  

任何人都可以帮忙？

解决方案

在数字前添加单个单引号'。然后Excel会将该数字视为字符串。

I was wondering if anyone had come across the following problem and had any ideas on how to resolve it: I'm exporting data from a C# application (.NET 3.5) to Excel (2003) via Interop. One of the columns stores a string value that appears to be numeric. That is to say it is a number that begins with a 0 e.g. 000123

I need the full number to be stored as it may be a serial number or something similar. Excel is not keen on this so I thought I could get around it by setting the destination cell to general. When I export to Excel I find 123 stored instead of 000123.

I've run through the app in debug and from the watchlist I've found that (for "Range range":

range.NumberFormat = "General"`
this.Rows[iGridRow].Cells[iGridCol].Value = "000123" '/* (datagrid is not truncating it)*/
range.Value2 = 123.0

It seems to be getting handled as a number even though I set the numberformat before this point:

range.NumberFormat = sNumberFormat;
range = (Range)sheet.Cells[iExcelRow, iExcelCol];
range.Value2 = this.Rows[iGridRow].Cells[iGridCol].Value.ToString();

Can anyone please help?

解决方案

Add a single apostrophe ' before the number. Excel will then treat the number as a string.
