CountOfCodes

The count of codes is not the count of UNWINDE_CODEs in but the number of 2 byte slots. Some UNWINDW_CODEs need more than one slot, thus the number of UNWIND_CODEs can be lower than the number in CountOfCodes.

Declaration
public byte CountOfCodes { get; set; }
Property Value
Type Description
System.Byte

EvenCountOfCodes

The count of UNWINDE_CODE slots allocated in PE file. For alignment purposes, this number is always even, so the final entry is potentially unused. In that case, the number is one longer than indicated by the CountOfCodes field.

Declaration
public int EvenCountOfCodes { get; }
Property Value
Type Description
System.Int32
