如何从CStringList中删除重复项？

Question

任何想法如何从CStringList删除重复的条目？

谢谢，

Answer 1

void RemoveDuplicates(CStringList &lst)
{
  for (POSITION pos=lst.GetHeadPosition(); pos; )
  {
    const CString &strValue = lst.GetNext(pos);

    // check next hits in the list
    for (POSITION pos2=pos; pos2; )
    {
      // Save current pointer
      POSITION posToDelete = pos2;
      const CString &strValue2 = lst.GetNext(pos2);
      if (strValue==strValue2)
      {
        // remove duplicate
        lst.RemoveAt(posToDelete);

        // There is a chance that we just deleted the follower from the outer loop
        if (posToDelete==pos)
          pos = pos2;
      }
    }
  }
}

Answer 2

下面是从CStringArray origData中删除重复值的代码，输出将存储在newData数组中：

CStringArray origData, newData;
CString csOld;
for(int i=0; i< origData.GetSize(); i++)
{
   if(i == 0 || csOld.Compare(origData[i] != 0)
   {
     csOld = origData[i];
     newData.Add(csOld);
   }
}
