Exporter DataGridView vers une page HTML

J’ai essayé de trouver une réponse à cette question et je n’ai eu aucun succès. Mon problème est le suivant. J’ai un comboBox qui répertorie différents formats pour exporter un rapport. Une de ces options est HTML. Fondamentalement, ce que je veux faire est de prendre le dataGridView dans un formulaire Windows et exporter tel quel vers une page HTML Je voudrais simplement exporter vers un tableau HTML. Je ne sais même pas comment commencer, alors je n’ai pas d’exemple de code à fournir. J’utilise c sharp 2008 windows app. Tout conseil serait grandement apprécié.

Voici une méthode que j’ai codée et qui inclut le formatage de DataGridView:

 public ssortingng ConvertDataGridViewToHTMLWithFormatting(DataGridView dgv) { SsortingngBuilder sb = new SsortingngBuilder(); //create html & table sb.AppendLine(""); sb.AppendLine(""); //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(""); } sb.AppendLine(""); //create table body for (int rowIndex = 0; rowIndex < dgv.Rows.Count; rowIndex++) { sb.AppendLine(""); foreach (DataGridViewCell dgvc in dgv.Rows[rowIndex].Cells) { sb.AppendLine(DGVCellToHTMLWithFormatting(dgv, rowIndex, dgvc.ColumnIndex)); ssortingng cellValue = dgvc.Value == null ? ssortingng.Empty : dgvc.Value.ToSsortingng(); sb.AppendLine(DGVCellFontAndValueToHTML(cellValue, dgvc.Style.Font)); sb.AppendLine(""); } sb.AppendLine(""); } //table footer & end of html file sb.AppendLine("
"); return sb.ToSsortingng(); } //TODO: Add more cell styles described here: https://msdn.microsoft.com/en-us/library/1yef90x0(v=vs.110).aspx public ssortingng DGVHeaderCellToHTMLWithFormatting(DataGridView dgv, int col) { SsortingngBuilder sb = new SsortingngBuilder(); sb.Append(""); return sb.ToSsortingng(); } public ssortingng DGVCellToHTMLWithFormatting(DataGridView dgv, int row, int col) { SsortingngBuilder sb = new SsortingngBuilder(); sb.Append(""); return sb.ToSsortingng(); } public ssortingng DGVCellColorToHTML(Color foreColor, Color backColor) { if (foreColor.Name == "0" && backColor.Name == "0") return ssortingng.Empty; SsortingngBuilder sb = new SsortingngBuilder(); sb.Append(" style=\""); if (foreColor.Name != "0" && backColor.Name != "0") { sb.Append("color:#"); sb.Append(foreColor.R.ToSsortingng("X2") + foreColor.G.ToSsortingng("X2") + foreColor.B.ToSsortingng("X2")); sb.Append("; background-color:#"); sb.Append(backColor.R.ToSsortingng("X2") + backColor.G.ToSsortingng("X2") + backColor.B.ToSsortingng("X2")); } else if (foreColor.Name != "0" && backColor.Name == "0") { sb.Append("color:#"); sb.Append(foreColor.R.ToSsortingng("X2") + foreColor.G.ToSsortingng("X2") + foreColor.B.ToSsortingng("X2")); } else //if (foreColor.Name == "0" && backColor.Name != "0") { sb.Append("background-color:#"); sb.Append(backColor.R.ToSsortingng("X2") + backColor.G.ToSsortingng("X2") + backColor.B.ToSsortingng("X2")); } sb.Append(";\""); return sb.ToSsortingng(); } public ssortingng DGVCellFontAndValueToHTML(ssortingng value,Font font) { //If no font has been set then assume its the default as someone would be expected in HTML or Excel if (font == null || font == this.Font && !(font.Bold | font.Italic | font.Underline | font.Ssortingkeout)) return value; SsortingngBuilder sb = new SsortingngBuilder(); sb.Append(" "); if (font.Bold) sb.Append(""); if (font.Italic) sb.Append(""); if (font.Ssortingkeout) sb.Append(""); //The  element was deprecated in HTML 4.01. The new HTML 5 tag is: text-decoration: underline if (font.Underline) sb.Append(""); ssortingng size = ssortingng.Empty; if (font.Size != this.Font.Size) size = "font-size: " + font.Size + "pt;"; //The  tag is not supported in HTML5.
