我正在代码中创建一个excel文件,如下面所示
Microsoft.Office.Interop.Excel.Application excelFile = CreateExcelFile();
现在我想将此excelFile转换为byte []而不保存到硬盘驱动器。怎么可能?

前段时间有同样的问题。您必须创建一个临时文件,然后将其读取为字节数组。
示例代码:
string tempPath = AppDomain.CurrentDomain.BaseDirectory + DateTime.Now.Hour + DateTime.Now.Minute + DateTime.Now.Second + DateTime.Now.Millisecond + "_temp";//date time added to be sure there are no name conflicts
workbook.SaveAs(tempPath, workbook.FileFormat);//create temporary file from the workbook
tempPath = workbook.FullName;//name of the file with path and extension
workbook.Close();
byte[] result = File.ReadAllBytes(tempPath);//change to byte[]
File.Delete(tempPath);//delete temporary file

这不是Excel File
它是用于Excel Automation的COM对象。它可用于请求Excel将文档保存到磁盘(作为临时文件),然后可以将其加载到byte[]
然后删除临时文件。
以下代码可用于为活动工作簿执行此操作:
public byte[] GetActiveWorkbook(Microsoft.Office.Interop.Excel.Application app)
{
string path = Path.GetTempFileName();
try
{
app.ActiveWorkbook.SaveCopyAs(path);
return File.ReadAllBytes(path);
}
finally
{
if(File.Exists(path))
File.Delete(path);
}
}
