检查字符串是否包含列表中的所有输入 [英] Check if the string contains all inputs on the list

问题描述

我希望能够检查字符串是否包含列表中保存的所有值；因此，仅当您的答案列表中包含所有关键词"时，它才会为您提供正确答案".这是我很累的东西，有一半失败了((不检查所有数组，只接受一个).代码我很累:

I want to be able to check if the string contains all the values held in the list; So it will only give you a 'correct answer' if you have all the 'key words' from the list in your answer. Heres something i tired which half fails;(Doesn't check for all the arrays, will accept just one). Code i tired:

 foreach (String s in KeyWords)
        {
            if (textBox1.Text.Contains(s))
            {
                correct += 1;
                MessageBox.Show("Correct!");
                LoadUp();
            }
            else
            {
                incorrect += 1;
                MessageBox.Show("Incorrect.");
                LoadUp();
            }
        }

基本上我想做的是:

问题:心理学的定义是什么?

Question: What is the definition of Psychology?

arraylist中的关键字:研究，心理过程，行为，人类

Key words in arraylist: study,mental process,behaviour,humans

答案:心理学是心理过程的研究，是人类

现在并且仅当以上答案包含所有关键字时，我的代码才会接受答案.我希望我对此很清楚.

Now if and ONLY if the answer above contains all key words will my code accept the answer. I hope i have been clear with this.

推荐答案

使用LINQ:

// case insensitive check to eliminate user input case differences
var invariantText = textBox1.Text.ToUpperInvariant();
bool matches = KeyWords.All(kw => invariantText.Contains(kw.ToUpperInvariant()));
