我的C#Web应用程序驻留在C
驱动器上。
但是,应用程序会从用户接收上载的文档并将其保存在D
驱动器上。
如何在D
驱动器上的Web应用程序中的HyperLink控件的NavigateUrl属性中指定C
驱动器上的文档路径。

在服务器端,您可以将文件加载到Stream
中,并将此对象作为byte[]
public void Page_Load(object sender, System.EventArgs e)
{
// create a FileStream from a path from local (D:, C:, E:, etc...)
FileStream file = File.OpenRead(@"d:\folder\yourfile.txt");
//Convert the stream to an array of bytes.
byte[] byteArray = file.ToArray();
// Clear all content output from the buffer stream
Response.Clear();
// Add a HTTP header to the output stream that specifies the default filename
// for the browser's download dialog
Response.AddHeader("Content-Disposition", "attachment; filename=foo.txt");
// Add a HTTP header to the output stream that contains the
// content length(File Size). This lets the browser know how much data is being transfered
Response.AddHeader("Content-Length", byteArray.Length.ToString());
// Set the HTTP MIME type of the output stream
Response.ContentType = "application/octet-stream";
// Write the data out to the client.
Response.BinaryWrite(byteArray);
}
