C＃range.Rows.Count计数不正确-Excel格式？

Question

I'm using C# to get data from Excel.

For reading out the Data I use this piece of code:

for (int rCnt = 2; rCnt <= range.Rows.Count; rCnt++)

The Sheet is 80 rows long, the range.Rows.Count says it is 135 rows long. I have this problem with 2 Excel Files. The Excel files are generated from an Sharepoint and have filters and some other formating. When I copy the data into an empty Excel file (with Strg + A, not manually selected) it counts the right amount of rows. With a 3rd Excel file (from an Sharepoint, too) its no problem...

Maybe a solution is to change the excel file first, it is only needed for my programm not for anything else, so that would be ok.

Any Ideas?

Edit:

I just stopped the code and saw, that after the range of 80, all the entries in the object are "null", so there is no hidden Data or something

Edit2: I deleted all the Data from that Sheet and now it counts 137 rows, so there has to be some formating stuff that is counted...

Answer 1

First of all you mention that the excel file has some filtering and formatting. Could it be that some of the formatting is applied to the first 135 rows in the file and therefore the select returns them all ? And secondly, what do you use to read the Excel file ? Do you use OleDb? And are the rest of the returned rows empty ?

If that is the case you can use : SELECT * FROM SHEET WHERE [Column] IS NOT NULL
