在C＃中從Excel中讀取列索引和列值

Question

我有一個ac＃應用程序，可以從excel文件中讀取數據。

我用了

Range xlRng = (Range)workSheet.get_Range("A1:B6", Missing.Value);

從A1到B6單元讀取值

如果我給定范圍，則需要讀取字典中的值，並且鍵名必須是單元格索引，並且值必須是對應的單元格值

核心價值

A1值1

B1值2

A2價值3

B2值4

Answer 1

您也可以嘗試

Excel.Range xlRng = (Excel.Range)workSheet.get_Range("A1:B6", Type.Missing);
Dictionary<string, string> dic = new Dictionary<string, string>();
foreach (Excel.Range cell in xlRng)
{

    string cellIndex = cell.get_AddressLocal(false, false, Excel.XlReferenceStyle.xlA1, Type.Missing, Type.Missing);
    string cellValue = Convert.ToString(cell.Value2);
    dic.Add(cellIndex, cellValue);
 }

如果您要使用與我相同的Excel名稱空間，請不要忘記導入名稱空間

using Excel = Microsoft.Office.Interop.Excel;

我希望這會有所幫助

您是否嘗試過EPPlus ？

以下是示例代碼，可以滿足您的要求：

void Main()
{
    var existingFile = new FileInfo(@"c:\temp\book1.xlsx");
    // Open and read the XlSX file.
    using (var package = new ExcelPackage(existingFile))
    {
        // Get the work book in the file
        ExcelWorkbook workBook = package.Workbook;
        if (workBook != null)
        {
            if (workBook.Worksheets.Count > 0)
            {
                // Get the first worksheet
                ExcelWorksheet sheet = workBook.Worksheets.First();

                // read some data
                Dictionary<string,double> cells = (from cell in sheet.Cells["A1:B6"] 
                            where cell.Start.Column == 1
                            select sheet.Cells[cell.Start.Row,cell.Start.Column,cell.Start.Row,2].Value)
                            .Cast<object[,]>()
                            .ToDictionary (k => k[0,0] as string, v => (double)(v[0,1]));

                //do what you need to do with the dictionary here....!
            }
        }
    }

}
