网页要求屏蔽右健，如何实现，谢谢

是web，不是winform

web的话放个链接，地址指向文件不就可以了

别人点后，我要统计，能具体点么，谢谢

string pathfile = @"D:\1.txt";//文件路径
FileStream fs = new FileStream(pathfile, FileMode.Open, FileAccess.Read);
long p = 0;
FileInfo fi = new FileInfo(pathfile);
long l = fi.Length;
if (Request.Headers["Range"] != null)
{
Response.StatusCode = 206;
p = long.Parse(Request.Headers["Range"].Replace("bytes=", "").Replace("-", ""));
}

Response.AddHeader("Content-Length", ((long)(l - p)).ToString());
if (p != 0)
{
Response.AddHeader("Content-Range", "bytes " + p.ToString() + "-" + ((long)(l - p)).ToString() + "/" + l.ToString());
}

Response.ContentType = "application/octet-stream";
Response.AddHeader("Content-Disposition", "attachment; filename=" + HttpUtility.UrlEncode(fi.Name));
fs.Position = p;

int i = 1;
byte[] b = new Byte[1024];
while (i > 0)
{
i = fs.Read(b, 0, b.Length);
Response.OutputStream.Write(b, 0, i);
}

fs.Close();
Response.End();

页面代码：

<script type="text/javascript">
            function download()
            {
                window.open('http://xxxxx.xxx/xxx.xxx');
            }
        </script>
        <asp:Button ID="Button1" runat="server" Text="下载" OnClientClick="download()" OnClick="Button1_Click" />

后台代码：

protected void Button1_Click(object sender, EventArgs e)
		{
			//统计代码
		}
