Question

C#用FileStream读取文件时,如何让进度条显示读取进度?

FileStream fs = new FileStream( strFile , FileMode.Open , FileAccess.Read ) ;

this.progressBar1.Value = position;
怎么让position随着fs的读取流的位置增长而增长.

给个vb.net的,自己改改局稿看,很简单的?
'先定义一个缓冲字节数组r
ProgressBar1.Maximum = CInt(fs.Length / r.Length)
fs.Position = 0
Do While fs.Position < fs.Length - 1
fs.Read(r, 0, r.Length)
ProgressBar1.PerformStep()'游差每读一次缓冲神腊皮进度条进一
Loop
