通过C#运行时无法识别BCDEDIT [英] BCDEDIT not recognized when running via C#

问题描述

当我尝试从C#应用程序运行BCDEDIT时，出现以下错误:

When i try to run BCDEDIT from my C# application i get the following error:

'bcdedit'不被识别为内部或外部命令，可操作的程序或批处理文件.

'bcdedit' is not recognized as an internal or external command, operable program or batch file.

当我通过提升的命令行运行它时，我得到了预期的结果.

when i run it via elevated command line i get as expected.

我使用了以下代码:

            Process p = new Process();
            p.StartInfo.UseShellExecute = false;
            p.StartInfo.RedirectStandardOutput = true;
            p.StartInfo.RedirectStandardError = true;
            p.StartInfo.FileName = @"CMD.EXE";
            p.StartInfo.Arguments = @"/C bcdedit";
            p.Start();
            string output = p.StandardOutput.ReadToEnd();
            String error = p.StandardError.ReadToEnd();
            p.WaitForExit();
            return output;

我也尝试使用

p.StartInfo.FileName = @"BCDEDIT.EXE";
p.StartInfo.Arguments = @"";

我尝试了以下操作:

1. 检查路径变量-很好.
2. 从提升的命令提示符下运行Visual Studio.
3. 放置完整路径.

我的想法不多了，关于为什么我会收到此错误的任何想法吗?

i am running out of ideas, any idea as to why i am getting this error ?

如果还有另一种方法也可以的话，我所需要的就是命令的输出.谢谢

all i need is the output of the command if there is another way that would work as well. thanks

推荐答案

有一种解释很有意义:

1. 您正在64位计算机上执行程序.
2. 您的C#程序构建为x86.
3. bcdedit.exe 文件存在于 C:\ Windows \ System32 中.
4. 尽管 C:\ Windows \ System32 位于系统路径上，但是在x86进程中，您必须遵守

1. You are executing the program on a 64 bit machine.
2. Your C# program is built as x86.
3. The bcdedit.exe file exists in C:\Windows\System32.
4. Although C:\Windows\System32 is on your system path, in an x86 process you are subject to the File System Redirector. Which means that C:\Windows\System32 actually resolves to C:\Windows\SysWOW64.
5. There is no 32 bit version of bcdedit.exe in C:\Windows\SysWOW64.

解决方案是将C#程序更改为目标 AnyCPU 或 x64 .

The solution is to change your C# program to target AnyCPU or x64.
