C++ JsonCpp Change objectValue from an arrayValue

我想更改slotList的值。

slotList[1][1] = "1234";

我该如何解决这个问题？

以下是我尝试过的：

JSON:

{
"slotList" : [
      [ "1452", "1452", "1452", "1452", "1452" ],
      [ "1452", "1452", "1452", "1452", "1452" ],
      [ "1452", "1452", "1452", "1452", "1452" ],
      [ "1452", "1452", "1452", "1452", "1452" ],
      [ "1452", "1452", "1452", "1452", "1452" ]
   ]
}

代码：

if (bIsParsed == true)
{
    Json::Value slotList = root["slotList"];
    Json::Value slot = slotList[currentIndex];
    Json::Value value = "111"; // what is wrong? do not change anything! OMG!
    slot[selectIndex].swap(value);
}
Json::StyledWriter writer;
string jsonData = writer.write(root);
