- String
The managed string to be copied.
nativeint
An unmanaged pointer to the BSTR, or 0 if s is null.
- Attributes
There is insufficient memory available.
The length for s is out of range.
StringToBSTR is useful for custom marshaling or when mixing managed and unmanaged code. Because this method allocates the unmanaged memory required for a string, always free the BSTR when finished by calling Marshal.FreeBSTR. This method provides the opposite functionality of Marshal.PtrToStringBSTR.
