从内存运行exe

以下是从内存加载运行exe的方法

bt = ReadFileFromEmbeddedResourcesAsByte("Calculator.exe");
bt = ReadFileAsByte("C:\\Calculator.exe");
if (!(bt == null)) {
    RunExecutableFromMemory(bt);
}
else {
    MsgBox("Error");
}

        if ((IO.File.Exists(Filepath) == false)) {
            MsgBox("File not exists");
            return null;
        }
        
        FileStream fstream = new FileStream(Filepath, FileMode.Open, FileAccess.Read);
        BinaryReader binReader = new BinaryReader(fstream);
        byte[] fbinary = null;
        try {
            fbinary = binReader.ReadBytes(Convert.ToInt32(fstream.Length));
