如何在不使用长度函数的情况下读取字符串或字符数组的字符

Question

I want to read all the characters from the string without using the built in functions.I tried the below.

        char[] str ={ 'k','r','i','s'};            
        for ( int i = 0; str[i]!='\0'; i++)
        {
            Console.WriteLine(str[i]);
        }

But I get an exception because unlike in c I don't see the string here ends with a null character. Is there any other way (apart from using built functions/try catch block in case of exception) I can read all the characters of the string ?

Answer 1

In c# arrays have Length property:

char[] str ={ 'k','r','i','s'};            
for (int i = 0; i < str.Length; i++)
{
    Console.WriteLine(str[i]);
}

Otherwise you can use foreach which will enumerate all characters in an array.

If what you really want is to display the string that the characters in the char array produce:

char[] mychars = { 'k', 'r', 'i', 's' };
Console.WriteLine("Your characters form the following string: " + new string(mychars));
