c# - Excel Interop 只读过滤行

Question

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后的单元格(可见)时:

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

调试:

当表没有被过滤时:

xlRange.Count: 15//表格中的元素总数

rowCount: 5//这包括标题

过滤表格时:

xlRange.Count: 9//这是正确的

rowCount: 1//这里应该是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 似乎与原始未过滤范围相同:

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，而不是关于行/列的文字。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();
}

当您指定范围内的行、列时，我怀疑它会转到该行(相对于范围)。

试一试，然后告诉我。
