導出DataGridView到HTML頁面

我試圖找到這個問題的答案，我沒有任何成功。我的問題是這個。我有一個comboBox列出不同的格式來導出報告。其中一個選項是HTML。基本上我想要做的是採取在窗體dataGridView並導出到HTML頁面。我想只導出到HTML表格。我甚至不知道如何開始，所以我沒有任何示例代碼提供。我正在使用c sharp 2008 windows應用程序。任何意見將不勝感激。導出DataGridView到HTML頁面

private StringBuilder DataGridtoHTML(DataGridView dg) 
{ 
    StringBuilder strB = new StringBuilder(); 
    //create html & table 
    strB.AppendLine("<html><body><center><" + 
       "table border='1' cellpadding='0' cellspacing='0'>"); 
    strB.AppendLine("<tr>"); 
    //cteate table header 
    for (int i = 0; i < dg.Columns.Count; i++) 
    { 
    strB.AppendLine("<td align='center' valign='middle'>" + 
        dg.Columns[i].HeaderText + "</td>"); 
    } 
    //create table body 
    strB.AppendLine("<tr>"); 
    for (int i = 0; i < dg.Rows.Count; i++) 
    { 
    strB.AppendLine("<tr>"); 
    foreach (DataGridViewCell dgvc in dg.Rows[i].Cells) 
    { 
     strB.AppendLine("<td align='center' valign='middle'>" + 
         dgvc.Value.ToString() + "</td>"); 
    } 
    strB.AppendLine("</tr>"); 

} 
//table footer & end of html file 
strB.AppendLine("</table></center></body></html>"); 
return strB;}

上面的代碼是從下面的鏈接，但我只是給你你需要什麼是DataGridView到HTML轉換。

下面是我編寫了包括在DataGridView的格式的方法：

public string ConvertDataGridViewToHTMLWithFormatting(DataGridView dgv) 
{ 
    StringBuilder sb = new StringBuilder(); 
    //create html & table 
    sb.AppendLine("<html><body><center><table border='1' cellpadding='0' cellspacing='0'>"); 
    sb.AppendLine("<tr>"); 
    //create table header 
    for (int i = 0; i < dgv.Columns.Count; i++) 
    { 
     sb.Append(DGVHeaderCellToHTMLWithFormatting(dgv, i)); 
     sb.Append(DGVCellFontAndValueToHTML(dgv.Columns[i].HeaderText, dgv.Columns[i].HeaderCell.Style.Font)); 
     sb.AppendLine("</td>"); 
    } 
    sb.AppendLine("</tr>"); 
    //create table body 
    for (int rowIndex = 0; rowIndex < dgv.Rows.Count; rowIndex++) 
    { 
     sb.AppendLine("<tr>"); 
     foreach (DataGridViewCell dgvc in dgv.Rows[rowIndex].Cells) 
     { 
      sb.AppendLine(DGVCellToHTMLWithFormatting(dgv, rowIndex, dgvc.ColumnIndex)); 
      string cellValue = dgvc.Value == null ? string.Empty : dgvc.Value.ToString(); 
      sb.AppendLine(DGVCellFontAndValueToHTML(cellValue, dgvc.Style.Font)); 
      sb.AppendLine("</td>"); 
     } 
     sb.AppendLine("</tr>"); 
    } 
    //table footer & end of html file 
    sb.AppendLine("</table></center></body></html>"); 
    return sb.ToString(); 
}

這應該是公認的答案，因爲它也輸出格式 –

參考我自己的答案http://stackoverflow.com/q/39210329/495455 –
