The <code>LastRowUsed()</code> function returns a row object. Use 

<pre><code>worksheet.LastRowUsed().RowNumber()

to get the number of the last row used.

You have to use <code>.LastRowUsed()</code>

I had this problem.
This example has the best performance:
<pre><code>XLWorkbook workbook = new XLWorkbook(FilePath);
// row count
var rowCount = workbook.Worksheet(1).LastRowUsed().RowNumber();
// column count
var columnCount = workbook.Worksheet(1).LastColumnUsed().ColumnNumber();
</code></pre>
or
<pre><code>XLWorkbook workbook = new XLWorkbook(FilePath);
// row count
var rowCount = workbook.Worksheet(1).RowsUsed().Count();
// column count
var columnCount = workbook.Worksheet(1).ColumnUsed().Count();
</code></pre>
I hope this helps you

I'm using ClosedXML with C# to modify an Excel workbook. I need to find the last row number used but <code>.RowCount()</code> counts how many rows are in the worksheet. So it is returning 1 million rows when there are only a few thousand. I have tried <code>LastRowUsed()</code> but that doesn't return an int and there is no <code>.row</code> method for it. How can I get the last row in an int?

ClosedXML find last row number

我使用ClosedXML和C#来修改Excel工作簿。我需要找到最后使用的行号，但是.RowCount()会计算工作表中有多少行。因此，当只有几千行时，它将返回100万行。我尝试过LastRowUsed()，但它不返回int，也没有.row方法。怎样才能得到int中的最后一行？
