Invalid Al. PtrToStringAnsi Chinese garbled characters,

Error code:

String dec = Marshal. PtrToStringAnsi (audioOutput. psz_description); // output bytes 0 bytes? (Realtek High Definition Audio)

Cause:

After checking the memory, we know that the memory encoding is UTF8, and Marshal does not support UTF conversion, so we must convert it to Unicode and then to UTF8.

Code after solution:

Byte [] bytes = System. Text. Encoding. Unicode. GetBytes (Marshal. PtrToStringUni (audioOutput. psz_description); // convert it to UNICODE Encoding

String dec = System. Text. Encoding. UTF8.GetString (bytes); // convert it to UTF8
