在C:\驱动器权限问题中写入文件 [英] Write file in C:\ drive permission issue

问题描述

我用c#开发了一个win应用程序，该应用程序在c:\驱动器的文件夹中生成文件.当尝试生成文件时，会出现权限问题，但是当应用程序在C:\以外的其他驱动器中生成文件时，则不会发生问题.因此，当我将我的应用程序设置分发给最终用户时，我将不会确保将要安装我的应用程序的用户确实具有在C:\驱动器中生成文件的权限.

i have developed a win application with c# which generate file in a folder in c:\ drive. when try to generate file there then problem occur for permission issue but when the application generate file in other drive than C:\ then no problem occur. so when i will distribute my apps setup to end user then i wont be sure that user who will install my apps does has the permission to generate file in C:\ drive.

所以指导我如何克服这个问题. 我应该在Win OS中使用清单来提升应用程序吗?

so guide me how can i overcome this issue. should i Using Manifests to Elevate an application in win OS?

etc......please guide me with right knowledge. thanks

推荐答案

您可以使用提升的权限再次启动您的应用程序，并在应用程序开始时进行一些检查以查看是否是这种情况.这是一个示例:(请注意不要陷入应用程序自身启动的无穷循环.)

You can start your application again with elevated permission and have some check at the application's start to see if this is the case. Here's an example: (Be careful not to get into an endless loop of the application starting itself.)

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
        string[] args = Environment.GetCommandLineArgs();
        if (args.Length > 1 && args[1] == "-e") Text = "Elevated";
    }

    private void button1_Click(object sender, EventArgs e)
    {
        Process process = new Process
        {
            StartInfo = new ProcessStartInfo
            {
                FileName = Application.ExecutablePath,
                Arguments = "-e",
                Verb = "runas",//-Admin.
            }
        };
        process.Start();
    }
}

但是，我同意将信息存储在"C:"中可能不是一个好主意.您可以尝试在类似Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData).

I agree, though, that storing information in "C:" is probably not a good idea. You can try someplace like: Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData).
