我想要达到的结果

    QByteArray S7comm;
    S7comm.resize(25);
    S7comm[0] = 0x03; S7comm[1] = 0x00; S7comm[2] = 0x00;
    S7comm[3] = 0x19; S7comm[4] = 0x02; S7comm[5] = 0xf0;
    S7comm[6] = 0x80; S7comm[7] = 0x32;
    S7comm[8] = 0x01; S7comm[9] = 0x00;
    S7comm[10] = 0x00; S7comm[11] = 0x00;
    S7comm[12] = 0x00; S7comm[13] = 0x00;
    S7comm[14] = 0x08; S7comm[15] = 0x00;
    S7comm[16] = 0x00; S7comm[17] = 0xf0;
    S7comm[18] = 0x00; S7comm[19] = 0x00;
    S7comm[20] = 0x03; S7comm[21] = 0x00;
    S7comm[22] = 0x03; S7comm[23] = 0x03; S7comm[24] = 0xc0;

怎么将以上数组转换为 qstring,不是一个元素一个字符串，而是一个字符串包含全部QByteArray
