如何获取包含提供值的 xlsx 单元格的地址？

Question

我在 c# 和 xlsx 文件中准备了一个字典，其中包含填充的列。如果单元格包含字典提供的值，我需要找到列和行的索引。

我正在使用 ExcelPackage 和 ExcelWorksheet。词典：

public static Dictionary<string, string> ExcelColumnsMapping = new Dictionary<string, string>()
{
    {"property name", "column name"}
}

XLS

var excelFile = new FileInfo(importFileFullPath);
 using (ExcelPackage package = new ExcelPackage(excelFile))
            {
                ExcelWorksheet worksheet = package.Workbook.Worksheets[1];           
            }

我想知道如何找到包含所提供数据的单元格索引。我想看一个带有任何字符串或其他内容的示例。谢谢你的帮助！

我不太明白你想做什么，但这是一种在 xlsx 文件中搜索值的方法，如果找到，returns 行和列。

using Excel = Microsoft.Office.Interop.Excel; //you should add the reference to that library for it to work

public Tuple<int, int> search(string Providedvalue)
{
    Excel.Application xlApp;
    Excel.Workbook xlWorkBook;
    Excel.Worksheet xlWorkSheet;
    Excel.Range range;

    string str;
    int rCnt;
    int cCnt;
    int rw = 0;
    int cl = 0;
    xlApp = new Excel.Application();
    xlWorkBook = xlApp.Workbooks.Open("path/exemple.xlsx", 0, true, 5, "", "", true, Excel.XlPlatform.xlWindows, "\t", false, false, 0, true, 1, 0);
    xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);

    range = xlWorkSheet.UsedRange;
    rw = range.Rows.Count;
    cl = range.Columns.Count;

    bool found = false;
    for (rCnt = 1; rCnt <= rw && found == false; rCnt++)
    {
            for (cCnt = 1; cCnt <= cl && found == false; cCnt++)
            {
                dynamic x = (range.Cells[rCnt, cCnt] as Excel.Range).Value2;
                str = x.ToString();
                if (Providedvalue == str)
                {
                    int line = rCnt;
                    int column = cCnt;
                    return new Tuple<int, int>(line, column);
                }
            }
    }
    return null;
}
