{
var fileName = @"C:\XML\Vehicles.xlsx";
using (SpreadsheetDocument spreadsheetDocument = SpreadsheetDocument.Open(fileName, false))
{
WorkbookPart workbookPart = spreadsheetDocument.WorkbookPart;
WorksheetPart worksheetPart = workbookPart.WorksheetParts.First();
SheetData sheetData = worksheetPart.Worksheet.Elements<SheetData>().First();
ArrayList data = new ArrayList();
foreach (Row r in sheetData.Elements<Row>())
{
foreach (Cell c in r.Elements<Cell>())
{
if (c.DataType != null && c.DataType == CellValues.SharedString)
{
var stringId = Convert.ToInt32(c.InnerText);
data.Add(workbookPart.SharedStringTablePart.SharedStringTable.Elements<SharedStringItem>().ElementAt(stringId).InnerText);
}
else if (c.InnerText != null || c.InnerText != string.Empty)
{
data.Add(c.InnerText);
}
}
}
Console.ReadKey();
}
}
}
}
现在，我想从特定列中提取值，并将这些值存储在字典中。.Dictionary<string, List<KeyValuePair<string, string>>>
示例输出如下：
10-01 List(Model=Fortuner, Type=SUV, MaxSpeed=200, Manufacturer=Toyota)
10-02 List(Model=Innova, Type=MPV, MaxSpeed=200, Manufacturer=Toyota)
10-03 List(Model=Altis, Type=Car, MaxSpeed=200, Manufacturer=Toyota)
10-04 List(Model=Land Cruiser, Type=SUV, MaxSpeed=200, Manufacturer=Toyota)
10-05 List(Model=Vios, Type=Car, MaxSpeed=200, Manufacturer=Toyota)
10-06 List(Model=Avanza, Type=MPV, MaxSpeed=200, Manufacturer=Toyota)
10-07 List(Model=Wigo, Type=Car, MaxSpeed=200, Manufacturer=Toyota)
10-08 List(Model=Rush, Type=SUV, MaxSpeed=200, Manufacturer=Toyota)
10-09 List(Model=Alphard, Type=Van, MaxSpeed=200, Manufacturer=Toyota)
10-10 List(Model=Hiace, Type=Van, MaxSpeed=200, Manufacturer=Toyota)
10-11 List(Model=Hilux, Type=Truck, MaxSpeed=200, Manufacturer=Toyota)
10-12 List(Model=City, Type=Car, MaxSpeed=200, Manufacturer=Honda)
10-13 List(Model=Brio, Type=Car, MaxSpeed=200, Manufacturer=Honda)
10-14 List(Model=Civic, Type=Car, MaxSpeed=200, Manufacturer=Honda)
10-15 List(Model=Jazz, Type=Car, MaxSpeed=200, Manufacturer=Honda)
10-16 List(Model=Accord, Type=Car, MaxSpeed=200, Manufacturer=Honda)
10-17 List(Model=Mobilio, Type=MPV, MaxSpeed=200, Manufacturer=Honda)
10-18 List(Model=CR-V, Type=SUV, MaxSpeed=200, Manufacturer=Honda)
10-19 List(Model=Odyssey, Type=Van, MaxSpeed=200, Manufacturer=Honda)
10-20 List(Model=Ranger, Type=Truck, MaxSpeed=200, Manufacturer=Ford)
10-21 List(Model=Expedition, Type=SUV, MaxSpeed=200, Manufacturer=Ford)

从下面的方法中，您可以将Excel工作表数据映射到Dictionary<string, List<KeyValuePair<string, string>>>。
public void MapExcelToDictionary()
{
var fileName = @"C:\XML\Vehicles.xlsx";
using (SpreadsheetDocument spreadsheetDocument = SpreadsheetDocument.Open(fileName, false))
{
WorkbookPart workbookPart = spreadsheetDocument.WorkbookPart;
//Get sheet from excel
var sheets = workbookPart.Workbook.Descendants<Sheet>();
//First sheet from excel
Sheet sheet = sheets.FirstOrDefault();
var worksheetPart = (WorksheetPart)workbookPart.GetPartById(sheet.Id);
var rows = worksheetPart.Worksheet.Descendants<Row>().ToList();
//Get all data rows from sheet
Row headerRow = rows.First();
var headerCells = headerRow.Elements<Cell>();
int totalColumns = headerCells.Count();
List<string> lstHeaders = new List<string>();
foreach (var value in headerCells)
{
var stringId = Convert.ToInt32(value.InnerText);
lstHeaders.Add(workbookPart.SharedStringTablePart.SharedStringTable.Elements<SharedStringItem>().ElementAt(stringId).InnerText);
}
// Remove the header row
rows.RemoveAt(0);
//Dictionary to map row data into key value pair
Dictionary<string, List<KeyValuePair<string, string>>> dict = new Dictionary<string, List<KeyValuePair<string, string>>>();
var productID = string.Empty;
//Iterate to all rows
foreach (Row r in rows)
{
List<KeyValuePair<string, string>> keyValuePairs = new List<KeyValuePair<string, string>>();
//Iterate to all cell in current row
foreach (Cell c in r.Elements<Cell>())
{
if (c.DataType != null && c.DataType == CellValues.SharedString)
{
var stringId = Convert.ToInt32(c.InnerText);
string val = workbookPart.SharedStringTablePart.SharedStringTable.Elements<SharedStringItem>().ElementAt(stringId).InnerText;
//Find cell index and map each cell and add in key value pair
switch (GetColumnIndex(c.CellReference))
{
case 1:
productID = val;
break;
case 2:
keyValuePairs.Add(new KeyValuePair<string, string>("Model", val));
break;
case 3:
keyValuePairs.Add(new KeyValuePair<string, string>("Type", val));
break;
case 4:
keyValuePairs.Add(new KeyValuePair<string, string>("Color", val));
break;
case 5:
keyValuePairs.Add(new KeyValuePair<string, string>("MaSpeed", val));
break;
case 6:
keyValuePairs.Add(new KeyValuePair<string, string>("Manufacturer", val));
break;
}
}
else if (c.InnerText != null || c.InnerText != string.Empty)
{
//Do code here
}
}
//Add productId and its repsective data to dictionary
dict.Add(productID, keyValuePairs);
}
Console.ReadKey();
}
}
下面的方法可以从Excel工作表中的单元格引用中找到列索引。
private static int? GetColumnIndex(string cellReference)
{
if (string.IsNullOrEmpty(cellReference))
{
return null;
}
string columnReference = Regex.Replace(cellReference.ToUpper(), @"[\d]", string.Empty);
int columnNumber = -1;
int mulitplier = 1;
foreach (char c in columnReference.ToCharArray().Reverse())
{
columnNumber += mulitplier * ((int)c - 64);
mulitplier = mulitplier * 26;
}
return columnNumber + 1;
}
