将Excel文件转换成HTML格式

Excel文件路径

public static void ExcelToHtmlFile(string ExcelFilePath)

{

Microsoft.Office.Interop.Excel.Application excelApp = new Microsoft.Office.Interop.Excel.Application();

Microsoft.Office.Interop.Excel.Workbook oBook = null;

缺省参数

object Unknown = Type.Missing;

try

{

目标html文件路径

object Target = ExcelFilePath.Substring(0, ExcelFilePath.LastIndexOf(".")) + ".html";

为了保险,只读方式打开

object readOnly = true;

指定另存为格式(html)

object format = Microsoft.Office.Interop.Excel.XlFileFormat.xlHtml;

打开Excel文件

oBook = excelApp.Workbooks.Open(ExcelFilePath, Unknown, readOnly,

Unknown, Unknown, Unknown, Unknown, Unknown, Unknown,

Unknown, Unknown, Unknown, Unknown, Unknown, Unknown);

转换格式

oBook.SaveAs(Target, format, Unknown, Unknown, Unknown, Unknown,

Microsoft.Office.Interop.Excel.XlSaveAsAccessMode.xlNoChange,

Unknown, Unknown, Unknown, Unknown, Unknown);

}

finally

{

if (oBook != null)

{

oBook.Close(false, Unknown, Unknown);

}

excelApp.Quit();

GC.Collect();

}
