UCHAR sample[2];
Sample[0] = 0X50 
Sample[1] = 0X43

我可以这样做吗？请通知

How can i do this? please advice me

推荐答案

您可以直接从字符串中使用 sscanf code>，如下所示：

You can scan the hex values directly from the string using sscanf(), something like below:

UCHAR sample[2];
for ( int i = 0; i < str.length() / 2 ; i++) {
    sscanf( (str.substr(i*2,2)).c_str(), "%hx", &sample[i]);
}

h

此外，假设 UCHAR <$> x / code>数组被声明为 string size的一半。

Also, this assumes that the UCHAR array is declared to be half as large as the string size.
