如果值包含逗号，如何使用QSetting读取值 [英] How to read a value using QSetting if the value contains comma character

问题描述

在我的QT项目中，我正在使用QSettings从.ini文件读取值.如果该值包含逗号字符，则QSettings无法读取它.我应该如何读取这些值?

In my QT project I am reading values from .ini file using QSettings. If the value contains comma character QSettings is not able to read it. How should I read such values?

推荐答案

逗号被QSettings视为列表分隔符.带有逗号的INI值将解析为字符串列表.您可以将字符串列表转换回原始字符串，如下所示:

Comma character is treated as list separator by QSettings. INI values with commas are parsed as string lists. You can convert a string list back to original string as follows:

QVariant value = settings.value("key");
QString string;
if (value.type() == QVariant::StringList) {
  string = value.toStringList().join(",");    
} else {
  string = value.toString();
}
