Allocates a managed string and copies all characters up to the first null character from a string stored in unmanaged memory into it.
Syntax
Parameters
- ptr
Returns
A managed string that holds a copy of the unmanaged string if the value of the ptr parameter is not null; otherwise, this method returns null.
Remarks
If the current platform is Unicode, each ANSI character is widened to a Unicode character and this method calls Marshal.PtrToStringUni(IntPtr, int). Otherwise, this method calls Marshal.PtrToStringAnsi(IntPtr).
Marshal.PtrToStringAuto(IntPtr, int) is useful for custom marshaling or when mixing managed and unmanaged code. Because this method creates a copy of the unmanaged string's contents, you must free the original string as appropriate. Marshal.PtrToStringAuto(IntPtr) provides the opposite functionality of the Marshal.StringToCoTaskMemAuto(string) and Marshal.StringToHGlobalAuto(string) methods.
