我正在尝试用 C# 编写一个小的 xlsx 到 csv（字符分隔值）程序（因为 windows 用户）。
我想成为一个逗号分隔值，但不是逗号，而是每个单元格都用不可见字符分隔，因为这是 hive 中的默认字符（我相信是'\001'）。
如何将此字符写入 C# 中的文件？我试过 "\001" , @"\001", "\uFEFF" 但没有成功..任何指针？
这是代码：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Excel = Microsoft.Office.Interop.Excel;
namespace excel2csv
{
class ExcelConverter
{
static void openExcel(string path,String outpath,String delim)
{
Excel.Application excelApp = new Excel.Application();
Excel.Workbook excelWorkbook = excelApp.Workbooks.Open(path, 0, false, 5, "", "", false, Excel.XlPlatform.xlWindows, "", true, false, 0, true, false, false);
foreach(Excel.Worksheet worksheet in excelWorkbook.Worksheets){
System.IO.StreamWriter file = new System.IO.StreamWriter(outpath+worksheet.Name+".csv", true);
Excel.Range usedRange = worksheet.UsedRange;
int nRows = usedRange.Rows.Count;
int nCols = usedRange.Columns.Count;
for (int iRow = 1; iRow <= nRows; iRow++)
{
String line = "";
for (int iCount = 1; iCount <= nCols; iCount++)
{
usedRange= (Microsoft.Office.Interop.Excel.Range)worksheet.Cells[iRow, iCount];
line += usedRange.Text + delim;
// Console.ReadLine();
}
Console.WriteLine();
file.WriteLine(line);
}
Console.WriteLine(worksheet.Name);
file.Close();
}
Console.Read();
excelWorkbook.Close();
}
static void Main(string[] args)
{
String path = @"C:\file.xlsx";
String outpath = @"file";
String delim = @"\001";
openExcel(path,outpath, delim);
}
}
}
