从CString中删除特定行

Question

如何从CString中删除特定行?这一行包含:"要删除的行"。

例如，输入为:

Remove Specific'n'
Line to remove'n'
Line From 'n'
CString C++.

输出应该是:

Remove Specific'n'
Line From 'n'
CString C++.

Answer 1

尝试CString。

将查找"要删除的行"的方法替换为NULL。

查看MSDN

Answer 2

您需要将内容逐行复制到除要删除的行外的其他新字符串中，然后再次将新字符串复制到旧字符串中

Answer 3

谢谢大家!方法就像Heena Goyal说的

CString oldString = _T("Remove Specific'n' Line to remove'n' Line From 'n' CString C++.");
    CString auxString ;
    CString newString =_T("");
    for (int i = 0; i < oldString.GetLength(); i++)
    {
        if (oldString[i] == 'n' || i == oldString.GetLength()-1)
        {
            if( i == oldString.GetLength() - 1)
                auxString += oldString[i];
            if(auxString.Find("Line to remove") == -1)
            {
                newString += auxString +'n';
            }
            auxString = _T("");
        }
        else
        {
            if (oldString[i] != 'r')
                auxString += oldString[i];
        }
    }
    newString = newString.Left(newString.GetLength() -1);
