我正在尝试让网站导出 .xlsm 文件，但似乎找不到任何有帮助的内容。这是我用来测试构建 .xlsx 文件（有效）的一个简单示例。
@using OfficeOpenXml;
<html>
<body>
<div id="page-wrapper">
@{
// Change file extension to xlsm to test
string fileExtension = "xlsm";
ExcelPackage p = new ExcelPackage();
p.Workbook.Worksheets.Add("Worksheet Name");
int LatestWorksheetNumber = p.Workbook.Worksheets.Count;
ExcelWorksheet ws = p.Workbook.Worksheets[LatestWorksheetNumber];
ws.Cells[1, 1].Value = "Test";
//Generate A File
Byte[] bin = p.GetAsByteArray();
string filename = "filename";
try
{
//Download the file as an attachment
Response.Clear();
Response.ClearContent();
Response.ClearHeaders();
Response.Cookies.Clear();
string ContentType = "";
if (fileExtension == "xlsx")
{
ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
}
else
{
ContentType = "application/vnd.ms-excel.sheet.macroEnabled.12";
}
Response.GetType();
Response.ContentType = ContentType;
Response.AddHeader("content-disposition", "attachment; filename=" + filename + "." + fileExtension);
Response.BinaryWrite(bin);
Response.End();
<p>File Created</p>
}
catch (Exception e)
{
<p>@e.Message</p>
}
}
</div>
</body>
</html>
将文件扩展名更改为 .xlsm 后，会生成文件，但当我尝试在 Excel 中打开该文件时，收到一条错误消息，指出扩展名不正确。我认为我唯一需要更改的是内容类型标头，但这显然不是问题。我还缺少什么？？？任何指导将不胜感激！
xiaoy312 解决了这个问题！添加p.Workbook.CreateVBAProject(); before Byte[] bin = p.GetAsByteArray();解决了我的问题！其他一切都保持不变，但 Excel 现在实际上会打开文件！这是我为有同样问题的人提供的最终代码：
@using OfficeOpenXml;
<html>
<body>
<div id="page-wrapper">
@{
// Change file extension to xlsm to test
string FileExtension = "xlsm";
ExcelPackage p = new ExcelPackage();
p.Workbook.Worksheets.Add("Worksheet Name");
int LatestWorksheetNumber = p.Workbook.Worksheets.Count;
ExcelWorksheet ws = p.Workbook.Worksheets[LatestWorksheetNumber];
ws.Cells[1, 1].Value = "Test";
p.Workbook.CreateVBAProject();
//Generate A File
Byte[] bin = p.GetAsByteArray();
string filename = "filename";
try
{
//Download the file as an attachment
Response.Clear();
Response.ClearContent();
Response.ClearHeaders();
Response.Cookies.Clear();
string ContentType = "";
if (FileExtension == "xlsx")
{
ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
}
else
{
ContentType = "application/vnd.ms-excel.sheet.macroEnabled.12";
}
Response.GetType();
Response.ContentType = ContentType;
Response.AddHeader("content-disposition", "attachment; filename=" + filename + "." + FileExtension);
Response.BinaryWrite(bin);
Response.End();
<p>File Created</p>
}
catch (Exception e)
{
<p>@e.Message</p>
}
}
</div>
</body>
</html>
