...EntireRow.RowHeight = value;

似乎是“Range.RowHeight”来修改范围的行高。http://msdn.microsoft.com/en-us/library/microsoft.office.tools.excel.namedrange.rowheight%28v=vs.80%29.aspx

我使用以下代码：

xlWorkSheet.Rows.RowHeight = height;
        xlWorkSheet.StandardWidth = width;

MySheet.UsedRange.EntireRow.Height = value;

MySheet.UsedRange.EntireRow.Height

只准备好了。可惜没用。
试试这个：

NamedRange.RowHeight = X;

请查看MSDN以获取更多信息：http://msdn.microsoft.com/en-us/library/microsoft.office.tools.excel.namedrange.rowheight%28v=vs.80%29.aspx

这对我很有效：

var SomeCell = (Excel.Range)_xlSheet.Cells[1, 1];             
SomeCell.Value2 = "What was D.D. Eisenhower's Gettysburg Address?";
SomeCell.RowHeight = 32;

试试这个
sampleRange.Resize.RowHeight=x; //x's type must int

试试这个，你可以用一个for循环来循环true所有的行

int i = 0;

        for (var i = 0; i < column.Count(); i++)
        {
            worksheet.Row(i).Height = 100;
        }

using (XLWorkbook xLWorkbook = new XLWorkbook())
       {
         var wordsheet = xLWorkbook.Worksheets.Add(dtEmpDetail, status);
         wordsheet.Row(2).Height = 50;
         wordsheet.Range("A1:d2").Merge();
        }
