我一直在努力，但我的 excel 表没有按照我的预期填充。如果内容具有字符串数据类型，那么工作表将显示“0”代替它，无论我如何努力使用转换。如果有人可以帮助我，我将在下面粘贴我的代码：
public static void WriteExcelDocument(string FilePath)
{
try
{
using (SpreadsheetDocument spreadSheet = SpreadsheetDocument.Open(FilePath, true))
{
WorkbookPart workbookPart = spreadSheet.WorkbookPart;
IEnumerable<Sheet> Sheets = spreadSheet.WorkbookPart.Workbook.GetFirstChild<Sheets>().Elements<Sheet>().Where(s => s.Name == "data");
if (Sheets.Count() == 0)
{
// The specified worksheet does not exist.
return;
}
string relationshipId = Sheets.First().Id.Value;
WorksheetPart worksheetPart = (WorksheetPart)spreadSheet.WorkbookPart.GetPartById(relationshipId);
SheetData sheetData = worksheetPart.Worksheet.GetFirstChild<SheetData>();
int index = 2;
SpectrumNewEntities context = new SpectrumNewEntities();
var q = from result in context.Appraisers
select result;
foreach (var g in q)
{
string Name = g.AppraiserName!=null?g.AppraiserName:String.Empty;
string city = g.City != null ? g.City : String.Empty;
string Address = g.Address != null ? g.Address : "NA";
int AppId = g.AppraiserAppraiserCompanyId != null ? (int)g.AppraiserAppraiserCompanyId : 0;
string email = g.Email != null ? g.Email : String.Empty;
Row contentRow = CreateContentRow(index, Name, city, Address, AppId,email);
index++;
sheetData.AppendChild(contentRow);
}
// Save the worksheet.
worksheetPart.Worksheet.Save();
}
}
catch (Exception)
{
throw;
}
}
private static Row CreateContentRow(int index, string Name, string city, string Address, int AppId, string email)
{
try
{
//Create new row
Row r = new Row();
r.RowIndex = (UInt32)index;
//First cell is a text cell, so create it and append it
Cell firstCell = CreateTextCell(headerColumns[0], Name, index);
r.AppendChild(firstCell);//
//create cells that contain data
for (int i = 1; i < headerColumns.Length; i++)
{
Cell c = new Cell();
c.CellReference = headerColumns[i] + index;
CellValue v = new CellValue();
if (i == 1)
{
v.Text = city.ToString();
}
if (i == 2)
{
v.Text = Address.ToString();
}
if (i == 3)
{
v.Text =AppId.ToString();
}
if (i == 4)
{
v.Text = email.ToString();
}
c.AppendChild(v);
r.AppendChild(c);
}
return r;
}
catch (Exception)
{
throw;
}
}
private static Cell CreateTextCell(string header, string Name,int index)
{
try
{
//Create a new inline string cell
Cell c = new Cell();
c.DataType = CellValues.InlineString;
c.CellReference = header + index;
//Add text to text cell
InlineString inlineString = new InlineString();
Text t = new Text();
t.Text = Name;
inlineString.AppendChild(t);
c.AppendChild(inlineString);
return c;
}
catch (Exception)
{
throw;
}
}
我不明白为什么显示是这样的？
