问题描述

你好，

当我在服务器上发布我的web应用程序后，代码没有读取文本文件值。但是当我在本地主机上运行web应用程序时，它的读取文本文件值。当我在服务器上托管我的网络应用程序时有什么问题，请给我解决方案如何从服务器上读取它？



我尝试过：

What I have tried:

string text;
var fileStream = new FileStream(@"c:\file.txt", FileMode.Open, FileAccess.Read);
using (var streamReader = new StreamReader(fileStream, Encoding.UTF8))
{
    text = streamReader.ReadToEnd();
}

推荐答案

当然不会 - 你会得到一种无效路径或安全例外。您无法访问虚拟根文件夹之外的C：\。



读取此内容： [ ^ ]

Of course it won't - you would get a form of invalid path or security exception. You can't access "C:\" outside of your virtual root folder.

Have a read of this: [^]

Quote：

readTextFile("file:///C:/MACID.txt");

JavaScript和WebApps没有直接访问权限o出于安全原因，用户文件系统。

读取本地文件的唯一方法是通过打开文件对话框和用户批准。

JavaScript and WebApps do not have direct access to user file system for security reasons.
The only way to read a local file is through 'open file' dialog and with user approval.
