问题描述
原始未筛选表
筛选表
我正在尝试使用Interop.Excel读取.xlsx文件。当我将xlRange变量设置为仅显示筛选出的单元格(可见)时,它似乎有一个奇怪的行为:
Excel.Range xlRange = xlWorksheet.UsedRange.SpecialCells(Excel.XlCellType.xlCellTypeVisible, Type.Missing);
调试:
当表未筛选时:
xlRange.Count:15//表中元素总数
rowCount:5//包括标题
筛选表时:
xlRange.Count:9//这是正确的
行数:1//应为3(包括表头)
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("
");
//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() + " ");
}
}
记住xlRange.Count是9,我应该能够手动访问所有3行,而不考虑rowCount变量,但xlRange似乎是相同的原始非筛选范围:
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
推荐答案
我怀疑您想要的是迭代.Rows
属性,而不是关于行/列的文字。大概是这样的:
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() + " ");
}
Console.WriteLine();
}
当您在某个范围内指定行、列时,我怀疑它将精确到该行(相对于该范围)。
试一试,让我知道。
