API调用解决思路

//API 原型int  GetPeopleName(char *strTmp, int *strLen)    //PB10.5中 我声明和调用的情况public function    integer  GetPeopleName(ref string strTmp,ref integer strLen)    library "termb.dll"    ls_name =''li_name = 30    GetPeopleName(ls_name,li_name)sle_name.text = ls_name//下面是C#里调用情况，测试通过[DllImport("termb.dll", EntryPoint = "GetPeopleName", CharSet = CharSet.Ansi, SetLastError = false)] public static extern unsafe int GetPeopleName(ref byte strTmp, ref int strLen);// 声明 byte[] name = new byte[30]; int length = 30; GetPeopleName(ref name[0], ref length);lblName.Text = System.Text.Encoding.GetEncoding("GB2312").GetString(name);//现在 我在PB里调用出现的情况是，sle_name.text 出现的是乱码，我不知道声明的数据类型对不对，还请各位指点
