How to read an exe file when it is running in C#

I am trying to read an exe file when it is running as follows:

FileStream fs = new FileStream(assemblyPath, FileMode.Open);
BinaryReader br = new BinaryReader(fs);
byte[] bin = br.ReadBytes(Convert.ToInt32(fs.Length));
fs.Close();

But an exception raises: The file cannot be accessed because it is occupied by another process.

However, I can copy this file using Windows Explorer. So it is possible to read this file. How can I read it in my program? Thanks!

Try with:

FileStream fs = 
    new FileStream(assemblyPath, FileMode.Open, FileAccess.Read, FileShare.Read);

The FileShare.Read flag is the key, it controls the kind of access other FileStream objects can have to the same file.
