计算一个字符并在 toolStripStatusLabel 中显示

Question

每次我将文本放入富文本框时，我想统计一下有多少个字符。

（如果我输入 'Hello there'（它应该显示“10 个字符...”而不是“2 个字符...”）

private void rtbText_TextChanged(object sender, EventArgs e)
        {
            char[] arrCharacter = new char[1] { ' ' };
            int countChar = rtbText.Text.Split(arrCharacter).Length;

            char[] arrVowels = new char[5] { 'a', 'e', 'i', 'o', 'u' };
            int countVowels = rtbText.Text.Split(arrVowels).Length;

            toolStripStatusLabel1.Text = countChar + " characters, of which " + countVowels + " are vowels.";
        }

肯定和这条线有关。事实上，它给了我字数而不是字数。

char[] arrCharacter = new char[1] { ' ' };

感谢您的帮助！

我觉得你的代码太复杂了:)

我会使用更像：

var vowels = new char[]{ 'a', 'e', 'i', 'o', 'u' };
var vowelCount = rtbText.Text.Count(c => vowels.Contains(c));
var characterCount = rtbText.Text.Length;
toolStripStatusLabel1.Text = characterCount + " characters, of which " 
    + vowelCount + " are vowels.";
