问题描述

我将datagridview的内容导出到excel文件中，由于没有记录，这花费了很多时间，我想到了在文件开始上传时显示一次进度条，而在文件上传完成时显示一次进度条.是否只能使用计时器或文件长度是否足够?谁能帮我.

如果在部分中写入文件流，则在Advance

Hi,

I am export the contents of datagridview to excel file and it take quite lot time due to the no of records, I thought of displaying a progress bar starting once when file starts uploading and end once when the file upload completes. Is it possible only with the timer or the file length is enough. Can anyone kindly assist me.

Thanks in Advance

推荐答案

文件长度就足够了.
将每个部分设置为1024个字节，对各个部分求和并按流长度指定

file length is enough if you write the filestream in parts.
Set each part to 1024 bytes, sum the parts and devide by streamlength
