原始未过滤表
过滤表
我正在尝试使用 Interop.Excel 读取 .xlsx 文件。 xlRange 变量似乎有一个奇怪的行为,当我将它设置为仅显示过滤的单元格(可见)时:
Excel.Range xlRange = xlWorksheet.UsedRange.SpecialCells(Excel.XlCellType.xlCellTypeVisible, Type.Missing);
调试:
当表格没有被过滤时:
xlRange.Count: 15 //表格中元素的总数
rowCount: 5 //那包括header
当表格被过滤时:
xlRange.Count: 9 //这是正确的
rowCount: 1 //这应该是3(包括header)
Excel.Application xlApp = new Excel.Application();
Excel.Workbook xlWorkbook = xlApp.Workbooks.Open(Directory.GetCurrentDirectory() + "\\Example.xlsx");
Excel._Worksheet xlWorksheet = xlWorkbook.Sheets[1];
Excel.Range xlRange = xlWorksheet.UsedRange.SpecialCells(Excel.XlCellType.xlCellTypeVisible, Type.Missing);
int rowCount = xlRange.Rows.Count;
int colCount = xlRange.Columns.Count;
//iterate over the rows and columns and print to the console as it appears in the file
//excel is not zero based!!
for (int i = 1; i <= rowCount; i++)
{
for (int j = 1; j <= colCount; j++)
{
//new line
if (j == 1)
Console.Write("\r\n");
//write the value to the console
if (xlRange.Cells[i, j] != null && xlRange.Cells[i, j].Value2 != null)
Console.Write(xlRange.Cells[i, j].Value2.ToString() + "\t");
}
}
考虑到 xlRange.Count 是 9,我应该能够手动访问所有 3 行而忽略 rowCount 变量,但 xlRange 似乎是相同的原始非过滤范围:
Console.WriteLine(xlRange.Cells[1, 1]);//Writes ID, Correct
Console.WriteLine(xlRange.Cells[2, 1]);//Writes 1, Should be 2
Console.WriteLine(xlRange.Cells[3, 1]);//Writes 2, Should be 4
Console.WriteLine(xlRange.Cells[4, 1]);//Writes 3, Should not be able to acces this element element at all because xlRange.Count is 9
