如何获取仅在具有值的Excel工作表的colums [英] How to get only those colums in a EXCEL worksheet that have a value

问题描述

我在C＃中编程读取Excel文件。

当我使用Excel.Worksheet.Columns.columns.count时， p>

但是我的excel表只有15列。如何获取只有那些值的列？

解决方案

这：

  Excel.Application demoApp = new Excel.Application（）; 
 demoApp.Workbooks.Open（fileName）; 
 int rowCount = demoApp.ActiveSheet.UsedRange.Rows.Count; 
 int colCount = demoApp.ActiveSheet.UsedRange.Columns.Count; 
  

所以，关键是使用 UsedRange 。

I am programatically reading an Excel file in C#.

When I use Excel.Worksheet.Columns.columns.count, I get a value above 16,000.

But my excel sheet has only 15 columns. How do I get only those columns that have a value?

解决方案

Here is how I usually do this:

Excel.Application demoApp= new Excel.Application();
demoApp.Workbooks.Open(fileName);
int rowCount = demoApp.ActiveSheet.UsedRange.Rows.Count;
int colCount = demoApp.ActiveSheet.UsedRange.Columns.Count;

so, the key is to use UsedRange, I hope this will help.
