如何在每个唯一字母后分割字符串

我目前正在尝试将用户选择的字符串关键字拆分为每个字母。但是,我无法说要在特定字母后进行拆分,因为在程序运行之前,我无法知道它将是哪个单词。我希望每个单独的字母都以某种方式分开存储,以便以后可以参考。

到目前为止,我已经尝试使用.Split方法执行此操作,并且如我的代码所示,没有运气。

int keyLength = txtKeyword.Text.Length;  // Calculate length of keyword
string KeyCount = txtKeyword.Text;      // Count the characters 
string[] Count3 = KeyCount.Split(char, StringSplitOptions.None);

string[] keywordArray = new string[keyLength];

for (int i = 0; i < keyLength ; i++)
{
    keywordArray[i] = Count3[i];

    listBox1.Items.Add(keywordArray[i]);
}

我在说“ char”的括号中出现错误,不确定为什么。

我建议使用:

char[] charArray = KeyCount.ToCharArray();

但是您的数据类型将是char[],而不是string[]

如果您确实需要字符串,可以这样做:

string[] stringArray = charArray.Select(c => c.ToString()).ToArray();

我希望我能很好地理解您的问题,但是对我来说这似乎太容易了,因为我根本没有使用split:

char[] splittedText;
string test = "narmin";

private void Window_Loaded(object sender, RoutedEventArgs e)
{
    splittedText = new char[test.Length];
    for (int i =0 ; i<test.Length;i++)
    {
       splittedText[i] = test[i];
    }
}

您收到一个错误,因为它期望一个select 'On-Site Case Rate' Exp1, CONCAT(isnull(sum(onsite.a) * 100 / count(onsite.casecount), 0), '%') '400', CONCAT(isnull(sum(onsite.b) * 100 / count(onsite.casecount), 0), '%') '401' from onsite ,而不是类型char。 以下是char方法的示例用法。

Split

如Compufreak所指出的,您可以使用string KeyCount = "1.2.3.4.5"; string[] Count3 = KeyCount.Split('.'); // Count3 would be ["1","2","3","4","5"] now // Note how the "." were cut during the Split operation string变成char[]。 这是使用原始ToCharArray()的各个字符的更深入的方法:

string

关于创建数组后如何访问字符的几种方法:

// Get the length of the Keyword (amount of characters in the string)    
int keyLength = txtKeyword.Text.Length; 

// Store the Text of the TextBox in a variable
string keywordString = txtKeyword.Text;

// Turn the string into an array of chars
char[] charArray = keywordString.ToCharArray(); 

// Turn the array of chars into an array of strings
string[] stringArray = charArray.Select(c => c.ToString()).ToArray(); 

但是,由于您可以像遍历// 1. Iterate through the array with a foreach loop foreach (char character in charArray) { // Do stuff with the character char tempChar = character; if (character == 'a') { // Do stuff } } // 2. Iterate through the array with a for loop for (int i = 0; i < charArray.Length; i++) { char tempChar = charArray[i]; } // 3. Get the character at a specific position (read: index) in the array char tempChat = charArray[0]; // The string array works exactly the same for all three methods foreach (string singleString in stringArray) { // Do stuff with the string string tempString = singleString; if (tempString == "a") { // Do stuff } } 一样遍历char数组,因此可以执行以下操作。请注意,我是如何使用string而不是新数组的。
