c＃确定文本是辅音，元音，数字还是其他字符。然后它显示每个的计数。

问题描述

我无法让代码计入输入文本框中的元音。我做错了什么？

I cannot get me code count the vowels in the entry text box. What have I done wrong?

string inputString;
inputString = this.entryTextBox.Text.ToLower();


char[] vowels = new char[] {'a', 'e', 'i', 'o', 'u'};
string vow = new string(vowels);

for (int index = 0; index < inputString.Length; index++)
{

    if (char.IsLetterOrDigit(inputString[index]))
    {
        if (inputString.Contains(vow))
                vowelCount++;

    }
    else if (char.IsDigit(inputString[index]))
       digitCount++;

}
    this.voweldisplayLabel.Text = vowelCount.ToString();
    this.digitsdisplayLabel.Text = digitCount.ToString();

推荐答案

if (System.Array.IndexOf(vowels, inputString[index]) >= 0)
   ++vowelCount;

-SA

string inputString;
inputString = this.entryTextBox.Text.ToLower();

char[] vowels = {'a', 'e', 'i', 'o', 'u'};
string vow;
int vowelCount = 0;
int digitCount = 0;


for int j = 0; j < 6; j++)
{
    vow = vow + vowels[j];
}

for (int index = 0; index < inputString.Length; index++)
{

    if (char.IsLetterOrDigit(inputString[index]))
    {
        if (inputString.Contains(vow))
                vowelCount++;

    }
    else if (char.IsDigit(inputString[index]))
       digitCount++;

}
    this.voweldisplayLabel.Text = vowelCount.ToString();
    this.digitsdisplayLabel.Text = digitCount.ToString();

所以你有，你的代码，翻新......或类似的......

So there you are, your code, refurbished ... or something like that ...
