感谢“改造”到一个Excel文件事先

Answer 1

它有点像这样（对不起，这不是完整的代码，但应该有所帮助）：

//Column headers 
static string[] headerColumns = new string[] { "A", "B", "C" }; 

//Used for header column counting 
static string alphabet = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"; 

     foreach (char c in alphabet.Split(alphabet[dt.Columns.Count])[0]) 
       headerColumns[alphabet.IndexOf(c)] = c.ToString(); 

      //Loops through the data table and appends the data rows onto sheet data 
      for (int r = 0; r < dt.Rows.Count; r++) 
      { 
       //Builds a list of values from the data row 
       List<string> values = new List<string>(); 
       for (int i = 0; i < dt.Columns.Count; i++) 
        values.Add(dt.Rows[r][i].ToString()); 

       //Creates a spreadsheet row from the list of values 
       Spreadsheet.Row contentRow = CreateContentRow(values, r + 2); 

       //Appends the row to the sheetData 
       sheetData.AppendChild(contentRow); 
      } 

    private static Spreadsheet.Row CreateContentRow(List<string> values, int index) 
    { 
     //Create the new row. 
     Spreadsheet.Row r = new Spreadsheet.Row(); 
     r.RowIndex = (UInt32)index; 

     //Create the cells that contain the data. 
     for (int i = 0; i < headerColumns.Length; i++) 
     { 
      Spreadsheet.Cell c = new Spreadsheet.Cell(); 
      c.CellReference = headerColumns[i] + index; 
      Spreadsheet.CellValue v = new Spreadsheet.CellValue(); 
      v.Text = values[i]; 
      c.AppendChild(v); 
      r.AppendChild(c); 
     } 
     return r; 
    }
