Find First Specific Byte in a Byte[] Array c#

I have a byte array and wish to find the first occurance (if any) of a specific byte.

Can you guys help me with a nice, elegant and efficient way to do it?

 /// Summary
/// Finds the first occurance of a specific byte in a byte array.
/// If not found, returns -1.
public int GetFirstOccurance(byte byteToFind, byte[] byteArray)
{

}
