Question

C# .net Framework 4.0
Is there a simple way to check if you have the rights to run a file?

Before i do this:

//e.g. Press a button
....
string exePath = "D:\something\something.exe";
Process.Start(exePath);

i would like to check if the user has the rights to run that file?
When i’m making the function call Process.Start, windows popsup with a messagebox and says that i’m not authorized to run this application and this application is “D:\something\something.dat” and NOT .exe?

How to check if you have permission to run a exe file?

EAFP: It is Easier to Ask Forgiveness than it is to get Permission.

So, you can surround your code with try/catch block:

try {
    Process.Start(path);
} catch (Win32Exception ex) {
    // ...
}

and you can use Win32Exception.NativeErrorCode to access the numeric representation of the error code associated with this exception.
