推荐答案

本方法适用于位于一个文件夹中任何可执行文件这是在Windows路径变量定义的：

This method works for any executable located in a folder which is defined in the windows PATH variable:

private string LocateEXE(String filename)
{
    String path = Environment.GetEnvironmentVariable("path");
    String[] folders = path.Split(';');
    foreach (String folder in folders)
    {
        if (File.Exists(folder + filename))
        {
            return folder + filename;
        } 
        else if (File.Exists(folder + "\\" + filename)) 
        {
            return folder + "\\" + filename;
        }
    }

    return String.Empty;
}

然后按如下方式使用它：

Then use it as follows:

string pathToExe = LocateEXE("example.exe");

就像弗雷德里克的方法，只找到一些可执行文件

Like Fredrik's method it only finds paths for some executables
