二进制源数据必须是一维的无符号字符数组。

Binary source data must be a single-dimensioned array of unsigned char.

例如，在将值传递给一个描述数据结构大小的方法时，应使用无符号整数而不是整数。

For example, when you pass a value to a method that describes the size of a data structure, use unsigned integer rather than integer.

无符号字符数据类型和二进制数据类型将产生错误的计算结果，会当成有符号的数据类型进行计算。

The unsigned char data type, and byte data type will yield incorrect results and act as though they are signed types i. e. type char.
