这行代码把Byte数组的二进制数据转换成一个合法的Visual Basic字符串。 三、 Byte数组和字符串之间的赋值 为了简化Byte数组和字符串之间的数据传递,允许你在任何动态Byte数组和任何字符串之间直接互相赋值。例如: Buffer=strA StrA=Buffer 注意: 当且仅当Byte数组是动态的,而不是固定大小时,
第一个参数的声明由一个ByVal字符串变成了一个ByRef的Byte数组,即由声明: ->ByVallpBufferAsString-> 变成了: ->ByReflpBufferAsByte-> 传递字符串时,需要一个ByVal修饰符来把字符串缓冲区传递到API函数中,因为字符串变量实际上指示了字符串内容所在的内存地址。在C语言术语中,这代表了一个指向指针的指针。
