Public Shared Function StringToBSTR (s As String) As IntPtr
Parameters
- s
- String
The managed string to be copied.
Returns
nativeint
An unmanaged pointer to the BSTR
, or 0 if s
is null.
- Attributes
Exceptions
There is insufficient memory available.
The length for s
is out of range.
Remarks
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.
