Excel Interop只读过滤的行

Question

原始未过滤表

已过滤表格

我正在尝试使用Interop.Excel读取.xlsx文件。将 xlRange 变量设置为仅显示已过滤的单元格（可见）时，它似乎具有奇怪的行为：

Excel.Range xlRange = xlWorksheet.UsedRange.SpecialCells(Excel.XlCellType.xlCellTypeVisible, Type.Missing);

调试：

未过滤表格时：

xlRange.Count：15 //表中元素总数

rowCount：5 //包括标题

过滤表格时：

xlRange.Count：9 //这是正确的

行数：1 //应为3（包括标题）

        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");
            }
        }

请记住，xlRange.Count为9，我应该能够手动访问所有3行，而不管rowCount变量如何，但xlRange似乎是相同的原始未过滤范围：

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

我怀疑您想要的是迭代.Rows属性，而不是按行/列的字面意思。像这样：

foreach (Excel.Range row in xlRange.Rows)
{
    for (int j = 1; j <= colCount; j++)
    {
        //write the value to the console
        if (row.Cells[1, j] != null && row.Cells[1, j].Value2 != null)
            Console.Write(row.Cells[1, j].Value2.ToString() + "\t");
    }

    Console.WriteLine();
}

当您指定行，范围内的列时，我怀疑它会转到该确切的行（相对于范围）。

尝试一下，让我知道。
