Question

我陷入了将PHP函数转换为C＃！

有人能告诉我自己做得不好吗？

原始代码（PHP）：

function delete_all_between($beginning, $end, $string)
{
    $beginningPos = strpos($string, $beginning);
    $endPos = strpos($string, $end);
    if ($beginningPos === false || $endPos === false) {
        return $string;
    }

    $textToDelete = substr($string, $beginningPos, ($endPos + strlen($end)) - $beginningPos);

    return str_replace($textToDelete, '', $string);
}

我的代码C＃：

string delete_all_between(string beginning, string end, string html)
{
    int beginningPos = html.IndexOf(beginning);
    int endPos = html.IndexOf(end);
    if (beginningPos == -1 || endPos == -1)
    {
        return html;
    }
}

我希望有人可以帮助我，我真的被卡住了！

使用Substring和Replace屏蔽并替换不需要的字符串。另外，我会添加一项检查以确保endPos > beginningPos：

string delete_all_between(string beginningstring, string endstring, string html)
{
    int beginningPos = html.IndexOf(beginningstring);
    int endPos = html.IndexOf(endstring);
    if (beginningPos != -1 && endPos != -1 && endPos > beginningPos) 
    {
        string textToDelete = html.Substring(beginningPos, (endPos - beginningPos) + endstring.Length); //mask out
        string newHtml = html.Replace(textToDelete, ""); //replace mask with empty string
        return newHtml; //return result
    }
    else return html; 
}

使用输入进行测试

delete_all_between("hello", "bye", "Some text hello remove this byethat I wrote")
