Win32Exception 参数不正确

发布于 2024-10-16 05:06:46 字数 211 浏览 4 评论 0原文

使用 Process.Start() 运行 exe 文件,但它抛出“Win32Exception 参数不正确”。

Process p = new Process();
Process.Start("C:\Program Files\APS2PP\keyl2000.exe");

我可以通过命令提示符成功运行该文件。

exe file using Process.Start() but it throws the "Win32Exception the parameter is incorrect".

Process p = new Process();
Process.Start("C:\Program Files\APS2PP\keyl2000.exe");

I can run this file through command prompt successfully.

Process.Start("C:\Program Files\APS2PP\keyl2000.exe")

使用双反斜杠或在字符串前面放置 @。

 Process.Start(@"C:\Program Files\APS2PP\keyl2000.exe");
Process.Start("C:\Program Files\APS2PP\keyl2000.exe")

Use double backslashes or put a @ in front of the string.

 Process.Start(@"C:\Program Files\APS2PP\keyl2000.exe");

Win32Exception - 发生错误打开关联文件时。

1) 如果您要使用 Process.Start(String) 的静态方法,则实际上不需要声明 Process 对象。

//Use...
Process p = new Process();
p.StartInfo = new ProcessStartInfo(filename);
p.Start();

//Or...

Process.Start(filename);

2)异常基本上是说由于某种原因无法打开该文件。你确定路径正确吗?您是否尝试过手动打开该文件?

3) 确保在更有条理的地方定义文件路径。例如设置文件。这也有助于消除转义字符的需要。但是,如果您坚持将该字符串保留为内联,至少可以通过在其前面添加 @ 符号来消除对转义字符的需要 (@"C:\Program Files\SomeFile.exe")

Win32Exception - An error occurred when opening the associated file.

1) If you're going to use the static method of Process.Start(String) you don't really need to declare a Process object.

//Use...
Process p = new Process();
p.StartInfo = new ProcessStartInfo(filename);
p.Start();

//Or...

Process.Start(filename);

2) The exception is basically saying that it can not open that file for some reason. Are you sure the path is correct? Have you tried opening that file manually?

3) Make sure to define your file paths somewhere more organized. Such as a settings file. This also helps eliminate the need for escaping the characters. But, if you insist on leaving that string inline, at least remove the need for escape characters by preceding it with the @ symbol (@"C:\Program Files\SomeFile.exe")

当我尝试将参数放在与可执行文件名称相同的字符串中时,我遇到了同样的错误,即相当于:

Process p = new Process();
Process.Start("C:\Program Files\APS2PP\keyl2000.exe /t keyfile.dat");

我没有意识到它们需要在单独的字符串中提供。

I had the same error when I tried putting arguments in the same string as the executable name, i.e. the equivalent of:

Process p = new Process();
Process.Start("C:\Program Files\APS2PP\keyl2000.exe /t keyfile.dat");

I didn't realise they need to be supplied in separate strings.
