C＃を使用してExcelファイルのセルフォーマットを取得する

Question

セルの色、フォントスタイル、枠線、セルのサイズなどのセルフォーマットを取得し、C＃を使用してxmlファイルとして保存する方法はありますか？

私はすでにセルの値を取得してxmlで変換するコードを持っていますが、各セルのフォーマットは取得できません。ありがとうございました。

あなたはあなたの細胞の表現にMicrosoft.Office.Interop.Excel.Rangeを使用していて、あなたはそれがrowNumberとcolumnNumberだ持っている場合。

string FontName = ((Range) worksheet.Cells[rowNumber,columnNumber]).Style.Font.Name 
int FontSize = System.Convert.ToInt32(((Range) worksheet.Cells[rowNumber,columnNumber]).Style.Font.Size); 

ボーダー（サイズ、スタイル）：

int size = System.Convert.ToInt32(((Range) worksheet.Cells[rowNumber,columnNumber]).Borders.Weight); 
Excel.XlLineStyle style = ((Range) worksheet.Cells[rowNumber,columnNumber]).Borders.LineStyle; 

列幅/高さ：

色用の

：フォントスタイル（のFontName、のFontSize）については

int colorNumber = System.Convert.ToInt32(((Range) worksheet.Cells[rowNumber,columnNumber]).Interior.Color); 
Color color = System.Drawing.ColorTranslator.FromOle(colorNumber); 

int width = System.Convert.ToInt32(((Range) worksheet.Cells[rowNumber,columnNumber]).EntireColumn.ColumnWidth); 
int height= System.Convert.ToInt32(((Range) worksheet.Cells[rowNumber,columnNumber]).EntireColumn.ColumnHeight);
