首先，设置字符串 -
string str = "Website";
Console.WriteLine("String: "+str);检查字符串中的每个字符并增加一个变量来计算该字符出现的次数 -
for (int j = 0; j < str.Length; j++) {
if (str[0] == str[j]) {
cal++;
}
}Example
您可以尝试运行以下代码来计算每个字符的出现次数。
演示示例
using System;
public class Demo {
public static void Main() {
string str = "Website";
Console.WriteLine("String: "+str);
while (str.Length > 0) {
Console.Write(str[0] + " = ");
int cal = 0;
for (int j = 0; j < str.Length; j++) {
if (str[0] == str[j]) {
cal++;
}
}
Console.WriteLine(cal);
str = str.Replace(str[0].ToString(), string.Empty);
}
Console.ReadLine();
}
}输出
String: Website W = 1 e = 2 b = 1 s = 1 i = 1 t = 1
