QString 的Split使用
可以使用split()函数将QString拆分成QStringList。split()函数的用法是QString.split(separator, behavior),其中separator是要拆分的字符串,behavior是一个可选参数,用于指定是否过滤空字符串。例如,如果要将字符串str按逗号拆分成QStringList,可以使用以下代码:
```cpp
QString str = "a,,b,c";
QStringList list = str.split(",");
```
这将得到一个QStringList,其中包含拆分后的字符串元素:["a", "", "b", "c"]。如果要过滤掉空字符串,可以在split()函数中添加QString::SkipEmptyParts参数:
```cpp
QStringList list = str.split(",", QString::SkipEmptyParts);
```
这样就会得到一个过滤掉了空字符串的QStringList:["a", "b", "c"]。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
